$13 vs $1,300 Exhaust System | CASH vs TRASH

How much power will a performance exhaust system make? And can you make your own and still get some solid gains? Today we're going to find out!
In this new series, we'll get an expensive intake system, and a home made system, then get an expert to decide. Along the way, one car will modified with loads of cash, and the other one will be modified with parts found from dumpster diving, recyclers, second hand parts or the cheapest parts we can find.
Thank you to Import Monster for importing the exhaust from Japan for us

I think the thing with backpressure is the wording. Backpressure in itself is always bad. You need exhaust velocity, Synchronized pressure pulses. If the headers are tunes standalone then what ever is behind it will not reduce performance if the size becomes bigger. If the headers are tuned with the rest of the exaust system, then it needs to carry the velocity of the exhaust through out the system. Exhaust systems and intake are extremely complex parts to make right, and you need a excellent understanding of fluid dynamics and math or simulation to get it right.

[@jckf]

This. Anyone who says an exhaust needs backpressure is just plain old fashioned wrong.

[@SvalPlays]

People talk about back-pressure, but what they really mean is flow rate. Opening up the exhaust does lower back-pressure, but that isn't what harms performance. It's the fact that the gas expands to fill the larger volume, which slows it down, which lowers performance. For every cylinder capacity there is an optimal exhaust size.

[@TheTardis157]

Yeah, It is all about velocity. Getting air in and out as quickly as possible is how you make the most power.

[@meola69420]

Pro is definitely on point with info. NA cars do make power with a good tuned header, I learned this in my old Spec Miata days when I was following a build that was done for the 2008 Targa Rally by the company Flyin Miata. When it comes down to turbo vehicles, log manifolds work just as well as a nice fancy one as the turbo itself is a huge restriction point, and also a muffler that evens out your exhaust pulses. 1.6L to 1.8L NA you don't really want to go over 2.25 or 2.5 inches in diameter.

[@Hrossey]

My wife married me cause she too refuses to go above 2.5 inches. Wait, what bro? 😂❤

yeah header design is everything. not all cars are the same though when it comes to exhaust. mostly all honda motors benefit greatly from 3in after the collector across the board over smaller sizes.

[@cademckee7276]

I’m tired of people saying turbo manifolds don’t matter, they do. Just look at any factory turbo race car, they have just as much work in the header as NA cars. It makes less a difference than NA, but it still makes a difference. If the engine can’t get rid of the air and breath properly you are loosing power

[@85gt]

[@vfxrgxttxnv1045]

[@Rippthrough]

Back pressure isn't a thing, all else being equal, lower back pressure means more power. The problem is if you go for less back pressure with a huge system you drop the exhaust velocity and that affects the scavenging. Resonance tuning is more important than either though. Back pressure is just a by-product of keeping the exhaust velocity reasonable - it's not wanted, nor needed. Any exhaust specialist that tells you otherwise doesn't do any proper tuning to time the exhaust to the cam and headflow, or other setup work bar banging on whichever aftermarket units that looked the shiniest at the time. Not that there's anything wrong with that, most paying work available is fitting rather than manufacturing bits, but it's still weird this stuff is still getting passed around in an era where you have the worlds knowledge at your fingertips. Unfortunately for the PeugBro, most of the restriction is in the manifold in those, there might be a couple of horses in the rest but you can get 8-10 horsepower out of a long-branch 4-2-1

The dude doesn't really knows what he is talking about. Engines doesn't need any backpressure, and the scavenging has nothing to do with back pressure. Its about exhaust flow speed and flow energy, and wave resonance. And btw that exhaust diameter change can be beneficial, if you place it in the correct distance after a header.

It is completely true about asking your exhaust shop about castoffs. If it's a good place, they'll have good castoffs. I got one for a truck I used to own.

Back pressure is absolutely a thing. Years ago I had a Gemini I did up as a hillclimb/time trial car, quite a lot of engine work, twin webers (IDFs), big cam, all the stuff. When I was done with motorsport I returned the Gemini back into a road car, milder cam, back to a single carb (Weber DGV), some other stuff to make it a more road friendly car my wife could drive, but the 3 inch race exhaust remained, albeit with a rear muffler so it would pass a roadworthy test. A few month after it was back on the road I caught the exhaust on a servo driveway and broke part of it so I took it to a shop and had a smaller (2 inch) system made. Much to my surprise there was a noticeable power gain from the 2 inch system. I would never have believed it had you told me that would happen, but that engine was definitely more tractable with the smaller exhaust. With the big cam and big carbs revving to 8000rpm the 3 inch made sense, but for a more conservative road car set up it was actually losing power. No kidding. That 3 inch system is WAAAAY too big for that little Pug. Match your exhaust size to your engine people.

[@whitebear96]

for N/A motor, backpressure is not something you want, it is an old myth saying that you need it, even the word itself is clearly telling that something is going against the flow, thus slowing gas flushing, which is bad. Powergain you observed was caused by speeding up the exhaust gas velocity in smaller pipe. In larger pipe, the gasses can expand and slow their flow out, when you replaced it by smaller diameter, the gasses could not expand as much and increased their velocity, , thus improving gas flushing.. As you said, correct pipe diameter is important, but backpressure is undesirable. If anyone is interested, I recommend Mikes video on backpressure on MotoIQ channel.

[@michaelblacktree]

Like mentioned above, the key is exhaust velocity. Not backpressure. If the exhaust gas has more kinetic energy, that will help evacuate the cylinder, and pull in the intake charge... i.e. scavenging.

[@LathanM]

I am loving this series. So many memories of the questionable things I did to my first tuner car.

[@player-i2101]

Peugeot exhaust is overkill for your setup. For a normal stage 1 TU5J4-TU5JP4 engine (Filter, Exhaust, Remap, Sport Cam Shafts) optimal exhaust internal diameter is 54mm with a Group N muffler at the end ! This diameter is good for engines under 160bhp. We put 2.5 inch external diameter exhaust on N/A TU engines that are 180bhp and over and for extreme N/A setups 220bhp+ we use 2.5inch internal diameter exhaust

[@sacrificialrubber779]

YOU DONT NEED BACKPRESSURE!! You need exhaust gas velocity to have effective scavenging. Going too big will kill exhaust gas velocity

[@silkysixx]

Man may make great exhausts, but his understanding of back pressure is way off. Scavenging requires high exhaust velocity and reflected pressure pulses. This is not the same as back pressure. Marty’s small pipe flaring into the 3” system actually a pretty decent design because, as the gases reach the expansion point, they slow dramatically which increases the pressure but also dictates a distance for pressure pulses to reflect back up the pipe to the manifold. That being said, with the stock log manifold, this matters about as much as it would on a turbo car.

[@BrodeyDoverosx]

You don’t NEED back pressure. This is ridiculously propagated and here we are, it’s propagated on MCM. Gale Banks >> Dale.

[@arashpanahi3621]

In all honesty, we still produce and use these 206s here in iran. Even for racing. Those engines can take a beating and parts are plentyfull and cheap. There are turbo 206s here that are pushing 500hp to the wheel and although those are for racing only, i have seen them reach 440hp easily while being driven daily. Just saying

[@ShadowGoddessSuzaku]

I think backpressure is a bit of a misnomer. You want higher exhaust velocity. Basically you want the pulses to siphon out the following pulses. Too large of an exhaust will not have a good siphon effect. There isnt a one-size-fits-all answer to how big an exhaust should be. There will always be a too small or too big balance.

I've been thinking about something else in the back of my Legacy (2.0 NA, 2001). When I bought it years ago, I visited a Subaru dealer and bought a new muffler as the original was rusted to heck. When I picked it up, I immediately noticed that it's not genuine, but an aftermarket piece. When I installed it, it sounded like crap at idle, with little farty sounds, like something inside would have a restrictor that is leaking. And I think it wreaks havoc around 2000-3000 RPM. Though the car has like diesel levels of torque but even at lower RPM's. For example, It cruises really nice with at a tad over 1500 RPM, 4th gear, 40 km/h. A while ago I stumbled upon factory brochure scans that listed a performance muffler. Also the car is so silent it's actually hard to know by ear where the RPM's are...

Alot of the boys used go cruising around their 106's and 206's and 306's (myself owned all of above at point or another), most of them lowered with body-kits and a mad big sticker on the back windows saying something crazy such as for example Drive It Like It Was Stolen or When In Doubt Go Flat Out, that was good old days until the they became cop magnets and the cops starting cracking down on them, all because alot people took their Peugeot's up the back roads going flat out and doing donuts. So when buying used check it's history because there is chance a young fellow could owned it and thrashed the life out of it.

Bigger pipe does not mean louder, that is a giant myth…. You proved it with the peugeot car . It’s much quieter than the swift. Bigger pipes are deeper sounding not louder.

[@matthewjenkins1161]

The big exhaust doesn't hurt power because of too little back pressure. An oversized system passing the same volume of gas, means the gas travels far slower, upsetting the scavenging. When sized just right, an exhaust has minimal back pressure reducing pumping losses, whilst maintaining just enough gas speed to pull the fresh charge through the inlet, on the valve overlap period.

I’m so happy y’all are still making videos. I Learned a hell of a lot of stuff from watching y’all’s videos. Started in school during welding class 2017. Love everything y’all are about, Can’t wait to see what y’all do next. much love you guys

[@claytonthorpe]

Take a drink every time Moog says “but that will require a tune”😂

[@EveryAdventure]

Watched it again to play the game and figured after a couple of sips that I needed a tune 🎶

[@Froudeybrand]

What’s the chances of anymore MCM branded high vis jumpers/jackets/vests? Would love a 6/7xl jacket or jumper already got the shirt.

[@mantravision69]

The new hoodie is sick, so to celebrate the new tune on my 5cyl turbo Ford Kuga (420Nm!!) I am splashing out on one. Love your work boys!

[@IBOO57]

Good to see Dale C*nt back!

[@fexdeth]

Martys car is so much cooler than the banana box will ever be, theres something to be said about creativity when you cant justify a thousand bucks for an exhaust

[@4krist]

in Peugeot change exhaust mainfold to 4-2-1 and gain from 109hp to around 125hp only with this mod....

[@Lvaneede]

I just had a custom exhaust put on my 53 year old Honda N360. It is much better now that is isnt leaking exhaust everywhere

[@LogiForce86]

I got the handvac (former model) but no matter which brand I ever tried in my life... they are all trash because they don't suck well enough.

[@StevenFalzon]

Perfect timing lads, just enough time to catch the Ep before work!!!

[@RandysRides]

My 74 Maverick had two connector sections of soup can and hose clamps. Problem fixed. lol

[@ningkandrawarny3761]

Bro i made a sick high performing exhaust for cheap, ZX2 (2.0 Zetec, 4 into 1 header, 2.5 inch all the way back, cat delete, 4.5 inch inlet TI rear pipe 17 inch long) just got headers n a rear pipe, had the shop do the rest. Cost around 350 total! Best exhaust amongst all my friends! Actually 5 of my buddies did what i did at my shop after that. Because a cat back was 650++, and was not near as high performing or smelly!!! 1300 for a rear section only = Waisted $! On a Swift = U figure it out... no Swif owner can afford 1300 rear section

[@puntomk1uk64]

Yes Peugeot's with cannons is a thing in the UK, these days it's more Vauxhall Corsas and Ford Fiesta's. So haven't seen one lately but in the hey day of the mid 2000's, modified 106's, 205's, 206's, and 306's were common. I like the Suzuki don't get me wrong, but I'm rooting for the 206 they're a great hatchback 👍 So c'mon Marty win this for the Europeans 😂

[@ricketyhermit2831]

Cheryl's Box is ALWAAYS worth the money. Especially if you want a bunch of stuff. I've ordered them multiple times and they always come in AWESOME. They come from the future if you live stateside (not really but timelines to e.s.t. means it's tomorrow down under). Even managed to get an item in the last box that bailed me out of a bad situation! Gotta love it... Thanks for everything guys, even though I know I'm a whisper in the crowd, always had a bit of fetish for Austrailia and that's what makes you guys perfect for my entertainment. Though I'll likely never meet or even know you personally I WILL visit your country one day!

I feel pretty confident in saying that you will lose a little power on the PugeBro with that exhaust. Making it bigger like that, on a N/A motor, will screw with your exhaust velocity, which will ultimately screw with whatever scavenging you had going on. Unless the factory exhaust was undersized in the first place, and you did some maths to determine your exhaust velocity and what the larger area of the new exhaust pipe does to it...I'm predicting less power. Edit: I just watched where the Pro talked about the exhausts. It's not backpressure that's helping with scavenging, it's exhaust velocity. Backpressure is bad. The exhaust velocity will be faster in a smaller pipe, slower in a larger pipe. There is a specific velocity, for that specific car, that will match with the engine pulses, and help draw out spent gases in the combustion chamber. I don't know what that velocity is without doing a bunch of math and knowing things I don't know about that car. So there's a window on the size of the pipe: too small is bad, too big is bad. In the case of the PugeBro, 3" exhaust is definitely on the "It's Too Big" side of the window. I'm agreeing with the Pro on Moog's muffler picking up more "power" than Marty's 3" pipe. Marty's is going to hurt power. Also, this is for a N/A car. Adding a turbo changes things entirely.

[@mikehorb9485]

Wrong, backpressure is bad all the time. Idk why nobody can explain/understand exhaust gas volume vs exhaust gas velocity. 3” pipe has volume but poor exhaust exit velocity. Nevermind “backpressure”, if your exhaust is engineered well enough, this “scavenging” effect could actually almost totally mitigate any resistance in exhaust flow. There will always be high pressure at the cylinder and valve, it’s how low can you get that number

[@zeropaloobatheuber1572]

I bought a Citroen DS3 6speed turbo with a cooked motor for $1300 Australian) and a low mileage written off Peugeot 308 for $1800. Pulled the motor and sold the rest. Now I have a fantastic little car for $2100. Obviously, with all the money I saved I could afford a set of pilot sport 5s. Very happy!

[@SpectreFTL]

when we design exhaust systems professionally, to clarify what they're on about re: "backpressure", maximizing flow (via the pipe energy equations, for you nerds) is about balancing two OPPOSING factors. flow rate is fixed and set by the heads/engine, called Q, where Q = area * flow velocity. as you change EITHER area OR flow velocity, it affects the other. if you move to a larger diameter exhaust, the flow velocity plummets; and you can constrict the exhaust to speed the flow up, but that restricts flow and increases losses from drag and fluid turbulence. at some point there is a sweet spot where their total flow is maximized. that is your ideal exhaust diameter. so no, back pressure doesn't matter. but you DO need to maintain flow velocity, so you HAVE to limit the size at some point. that's what they're getting at in a roundabout way. what boomers call back pressure is actually "head loss", a term for parasitic losses in things like curves in the pipe, catalytic converters and mufflers, marty's little contorted colon tube, etc. you want to MINIMIZE head loss as much as you possibly can as it results in direct power increase even at the same flow conditions. scavenging is about tuning the exhaust (and mostly header) length so that the individual pulses out of the cylinders arrive perfectly timed and cause a little vacuum to pull the exhaust out on the next stroke. that (and intakes!) are tuned lengths set by the frequency of the intake or exhaust valves at your target RPM. there is a reflected wave whenever you move from one diameter to another, such as at the collector of headers. you match these frequencies together to get scavenging. headers require tunes to set the timing (and therefore intake frequency) for your aftermarket header length. things that affect scavenging (such as headers, intakes, Y-pipes) or confuse the MAF sensor require a tune to make power. things that reduce head losses (ie, cat delete, intake air FILTER) will show immediate power improvement and do not necessarily need a tune, but they will make even more benefit with one. this is because head loss exists AT THE SAME FLOW RATE, it has nothing to do with "flowing better" -- remember that the Q flow rate is FIXED by the heads and applies to the ENTIRE exhaust in all locations!

Pug over the Swift every day!

[@babovicj.1939]

If you could find 106 gti cams with pulleys or c2 vts head/ cams/ intake manifold w larger throttle body (fly by wire 406 maybe, not sure), 4-2-1/ 4-1 manifold and reprogram it it would be a true rocket. Easy 150/160hp.
