[@nickmorano6640]

I have an s280 fiesta st (just like the big turbo one reviewed on this Channel) and it’s straight piped currently just because I got a good deal on the exhaust and it’s a side exit so that’s bad ass too. I’m currently in the market for a valved muffler to put on it though because I’m turbo back 3in right now but at my current power level I’d be ok at 2.75in so I might as well add the ability to be halfway quiet when I wanna be even if when the valve is closed it does add some restriction

[@nickmorano6640]

No I don’t have the pop and bang tune like all of the other st’s……. I’m an adult

[@TwoDollarGararge]

The issue is most people who run a straight pipe are broke or cheap and don't set it up right. One lesson, my dad taught me with project cars. Just keep it stock until you can get a quality part.

[@monikhushalpuri]

I disagree, best exhaust set up for a 1994-2004 mustang gt is 2 high flow cats, stock or upgraded shorty headers, H pipe or no crossover at all and NO mufflers...as long as you got high flow cats it doesn't drone, sounds great, isn't too loud unless you're going WOT. So depends on the car tbh I've heard aftermarket systems that just don't sound as good as much simpler mods. Main problem is most of these guys are putting bigger diameter piping on cars they will never take to a track

[@aluminumfalcon552]

Been keeping my Golf stock for 7 years, except for the tune, upgraded brakes and better tires. My car will NEVER be hacked.

[@monikhushalpuri]

@aluminumfalcon552 if your golf is turbo it would actually benefit from a more free flowing exhaust to help keep exhaust temps down especially if tuned, 3 inch or bigger downpipe will actually benefit it longevity wise for the turbo and help keep EGT's down, it'll help keep your oil from breaking down too fast, some mods are actually good especially if exhaust related for turbos

[@IraqVet0608]

[@damascus-ut1ee]

The problem with Borla, Flowmaster and Magnaflow historically is they have never addressed drone until pretty recently. It’s good to see them address it. In the past, Corsa has really only been the one to directly solve drone while giving you increased volume. Sometimes even modifying the stock systems have a better outcome than older Borla/FM/MF systems as far as brain-rattling drone.

[@damascus-ut1ee]

I’d also argue on his point about perforations in the pipe. It’s not quite that simple. On a golf ball you might have some speed to the air but nothing like exhaust gas or sound wave speeds exiting the combustion chamber. It really has to do more so with the system as whole though, and individual pieces like that can’t be singled out. You can absolutely have some straight pipe that flows better than some mufflers, and vice versa. It depends on how the gasses are being evacuated, and how the resonance and tuning is to extract said pressure waves/pulses (and at what RPM.)

[@Fall2Caine]

Saying corsa exhaust systems are anything but loud and raspy is insane. Every s550 or camaro owner I've ever known to have a Corsa system, has said the same thing about it

[@ryurc3033]

Dual 2.5 pipes with magnaflows didn't drone at all on my 76 Silverado with a mild 454. 3 inch pipes would drone like crazy...2 1/2 not at all. Tailpipes also make a huge difference compared to turn downs(that echo off the ground and rattle the cab) or side exit.

[@hatch450sx3]

Steeda and AWE have no drone either. Stop being cheap with exhaust.

[@damascus-ut1ee]

That’s way too generalized. Sure Corsa used to offer touring and sport systems and seem to only offer the extreme variants on some of their cars now. However: some cars don’t sound raspy at all with the “extreme” versions and some do.

[@justinmurphy7173]

1. Nobody straight piping thier car becuse it's better. It's becuse it's cheaper. 2. The dyno says otherwise.

[@rightwingsafetysquad9872]

[@Sr1l_kr1l]

An exhaust doesnt do much for performance

[@Lofi.z34]

My straight-pipe setup was nearly $4000 and it was worth every penny, for the sound and the power output. My parts are used on actual track cars though, not some cheap street exhaust

[@kshepthedrummer]

The "muffler flows more than a straight pipe" argument is basically a moot point. The muffler may flow 700cfm, but the rest of the 3inch tubing in the exhaust is still only flowing the 660cfm like the "straight pipe" section, less with bends and flange disruptions. So adding ~18" of 700cfm muffler doesn't mean your whole exhaust now flows 700cfm. You can put a 4" muffler on a 2.5" exhaust, that doesn't mean your exhaust now flows what a full 4" exhaust can flow. As long as the muffler/straight pipe isn't MORE restrictive than the rest of the exhaust, it basically doesn't matter what it can flow.

[@armandocardona6975]

You are missing the point of the demonstration. Most believe mufflers muffle noise by slowing air down. The demo was about how you can add a muffler without hurting performance.

[@soleboy187]

[@Lofi.z34]

Straight-pipes are good if you do it correctly. On my 370z I run $2417 PPE Engineering equal-length long tube headers with $1442 Fast Intentions TDX dual exhaust, where I cut out the 10" mufflers and had a seasoned welder neatly weld in T-304 2.5" stainless pipe, so I can have a true-dual full straight pipes. It sounds like a jet fighter above 3k rpm and brings everyone who isn't a grandma excitement. People don't expect it to sound that good. Also, I wouldn't expect Magnaflow to know much about airflow, they are the cheap end of exhausts. Go talk to a racing team that builds exhaust for track cars.

[@karlkronic]

I wouldn’t ask a muffler company performance questions in regards to muffler vs. no muffler lol. You might aswell be asking the epa. Every popular ford and gm tuner would say to do straight pipe/catless/dumps… whatever the least restrictive setup your willing to run, if you want all the power. The volume is a side effect, not why they’re doing it.

Great content David! I have really liked the way Magnaflow systems sounded on my cars but it was cool to see the engineering explained behind the design and the thought process they put behind it all. Straight piping sounds too much like a desperate shreak to throw a rod and drones way too loudly even when far away on so many cars so I would never want to do it. Knowing how Magnaflow used the perforations in the full body mufflers to break up the exhausts laminar flow and actually unlock more power makes my favorite exhaust choice even more worth it.

[@Justdriv3]

The older ive got (im in my 20s) ive leaned towards quieter exhaust setups , i used to love the sound of my open downpipe 2.3 turbo but now ive grown out of that and now have a full exhaust on that car, recently 351c swapped one of my foxes and decided on just doing an h pipe with flowmasters into 2.5 inch tailpipes.

[@Scoots1994]

I don't buy that equal tube vs muffler the muffler has better flow. I hate no muffler, no resonator setups, but I've spent a LOT of time on dynos and never seen a muffler ADD power on a race car that had to add it for noise limited circuits. And believe me we were looking for every HP we could find. If your point is that straight piped street cars are a nuisance for the owner (cops) and neighbors of the owner, and the loss of performance from a muffler is minimal, while the tone can still be pleasing? Then fine. But the implication is performance is IMPROVED by adding a muffler, and that I do not buy.

[@LapoftheWorld]

Always love seeing real science on the internet. Obviously you have to apply critical thinking because they have a vested interest in selling mufflers/exhaust systems, but the comparison of perforated vs the smooth pipe does track with other examples of airflow over surfaces (e.g. golf-ball effect). Also definitely appreciate the attention to drone as someone who covers a LOT of miles in a car that I'd also like to sound good.

[@gordydexter2615]

Good video but there was zero discussion on power output. Steeda did a Dyno video and sound comparison using decibel readers and it was very informative. Throughout the history of the Gen 3 Coyote S550 Mustang we picked up more RWH with the X pipe over the H pipe. On the S550 we saw minimal 3 RWH Gain on the H pipe and deeper tone and the X pipe 10+ RWH gain and more raspy tone. But now on the S650 Gen 4 Coyote Mustang Steeda found just the opposite results. 1-2 RWH with the X pipe still being louder and raspy sound but 10+ RWH gain on the H-pipe and much improved deeper bass sound also. Hence the Pennsylvania company AWE Switchpath catback system with included H pipe puts out better deeper sound and 10+ RWH. Same results with the Borla S type switch path exhaust both companies allowing the valved exhaust option so you don’t give up the expensive option Ford AE exhaust. I have the magnaflow exhaust on my Ford F-150 but when my Dark Horse comes in I will be buying the AWE Switch-path exhaust which provides an increase of 10 rear wheel horsepower and a better H pipe deep sound with the gurgles and pops as you down shift. Still would like to hear if the magnaflow picked up any RWH!!!!!! Cheers ‼️👍👊💪🇺🇸🐎

My 05 gmc sierra slt 1500 with the L33 5.3 sounded sooo good with just a muffler delete. Some drone, not annoying bad, small cold start rasp but only then throughout rev range. Nice deep, deep downshift literal growling sound. Almost like a jake on a gas v8 lol. The regular magnaflow muffler 2.5" center in 2.5" offset out that I purchased for inspection uses only bc it was brand new mounted and ran for 10 mins until seller didnt lime it so i got half off lol. It does honestly sound very very good on my 5.3 with stock manifolds, cats, and tailpipe single out behind pass back tire no tip. I was actually dissapointed I didnt try it way sooner. The down shift sound is very aggressively deep and has some deep pops and that growl at certain rpm's on decel. Kinda loud from 10-50% throttle, 50-WOT IS A STRAIGHT UP RACE TRUCK SOUND. HOMEMADE COLD AIR INTAKE WITH TRUE COLD AIR DUCTING FOR NO RADIATOR COLD AIR LOL. GAVE IT A TOTALLY DIFFERENT SOUND. I LOVE A DEEP FLOWMASTER SOUND ON V8 AND THE MAGNAFLOW WILL NOT DISSAPOINT AFTER SOME DRIVING AND THINGS PACK IN A COVER UP A LITTLE MORE INSIDE THE MUFFLER. I DON'T THINK MOST PEOPLE NOT POSTING VIDEOS OF THEIR OWN CAR WITH THE MAGNAFLOW MUFFLER INSTALLED PROPERLY AND NOT LEAKING ALLOT OF THE SOUND OUT UNDER THEIR CAR OR TRUCK REALLY UNDERSTAMD OR HEAR JUST HOW ACTUALLY GOOD IT DOES SOUND.

[@bobboy5508]

The Cadillac ATS-V exhaust does what he described of the Mustang. In tour the valve is to silence sound. But in sport and track the valve goes to straight, giving the sound. But, I hear the valve closing and opening depending on throttle position. By that I don’t hear the valve but I hear the exhaust change after backing of throttle to cruise at the same speed. So I hear the exhaust noise change. So I believe it to be the same where it will open a close the exhaust based on throttle. And he said that’s a good thing. Well ok. I know it opens right up when I hit the pedal. Pretty cool tech from the factory.

[@timothybayliss6680]

The problem...thats not a piece of strait 3" tubing, its also belled the opposite way for best flow. I am assuming that its 0.065 wall, that means the internal passage of the mufflers is almost 9% larger. A piece of tubing at that size would flow 720cfm with the same pressure drop. This is dirty.

[@OJLFMU]

Yup pipe is swedged at the bottom, while the muffler inlets fit over easily… the others don’t have the expansion markings nor do they appear to have room to have been swedged before the muffler body. So what’s 3 inches the pipe or the muffler?

[@meanman6992]

Going to guess before I watch this applies to NA and maybe supercharged engines…. Turbos want max delta (differential in pressure from manifold side to post turbine for fastest spool up and least restriction. People confuse back pressure and exhaust velocity…. Higher exhaust velocity = best. The problem is that higher exhaust velocity at low rpm will restrict higher rpm performance and bigger exhaust will have low velocity at low rpm but not restrict the top end… If you could have your cake and eat it too, you’d have an expanding exhaust that would go from a small diameter at low rpm and grow larger and rpm/ flow increases to keep velocity as high as possible without choking the engine. When he starts talking about surface area, he’s talking about surface tension/drag with the gasses interacting and dragging on the sides of the pipe, same thing has to be accounted for in plumbing. A narrow pipe may be fine if it doesn’t have to go far, but if it has to go real far you’ll need a larger pipe to reduce the restriction via surface area drag which will lower water pressure over distance… main difference is the static input from a water line vs dynamic input to an exhaust from an engine going through its rev range. Highest exhaust velocity also helps maximize scavenging (if it’s being utilized, which it should be)

[@ChavaYang]

Thaank you for the video. Very informative, very demure.

[@RunningSolo]

Great information bro !!!

[@hokage_smoke]

@4:08 the same thing applies to engine building in general the biggest most smooth port and cam will not always translate to more hp smaller tubes means more velocity but bigger means lower velocity so basically the air gets lazy and doesn't flow as well its a balancing act.

[@kylebeach2316]

Heres the other factor with exchaust systems. As they age the packing inside the systems will break down over time and will slowly make them louder and louder. I know that for a fact cause im constantly at motocross tracks and you can tell who takes care of their exchaust systems by replacing the packing too make it sound good and not abnoxious while some people dont care and the packing is "blown out." The bikes that do are stupid loud just like a honda civic at 3 am with a straight pipe slapped on it.
