It’s a type of muffler but not exactly the same thing it just reduces a different frequency. This mechanic has no idea what he’s talking about these engines.

I'd say the point he was trying to get across is quality matters. Do not to cheap out on things that aren't beneficial in value or low end performance. Considering mopars NA already get beat up on the low end where that torque needs to assist moving all the additional weight

I have a question if you could answer it. My 2014 SXT Blacktop Charger (bought last year as is) it already has Magnaflows on it and a rear muffler delete. My pipes are 2inch from cats - back end. My question is: If I get my pipes redo and bigger to 2.5’inch all the way through so I can weld on my 2.5’inch tips. Would I have to get a Dyno or re checked? Or would I be fine.

[@unccliff1]

@@Shhoooop a tune with any modification never hurts

[@Mikes05Hemi]

It's ok guys. I promise a mid muffler delete is perfectly fine and absolutely does not affect performance in any way on these cars, good nor bad. The middle muffler, is a muffler. The resonator at the tail of the exhaust is a resonator. Words have meaning use them correctly. This gentleman is correct on one issue. People have got to stop removing catalytic converters or installing headers without getting the car tuned. Keep in mind this gentleman has a job to do, and that's what he's doing.

[@2dudescamp]

Agree with you and @Mikes05Hemi. This guy does talk a lot, and not all true. Really, the only true statement is properly tuning after any header replacement. Any piping work after the cats have zero effect on engine performance. Also, like so many who don’t quite understand fluid dynamics as it relates to automotive exhausts, “back pressure” is absolutely not what you want. That hinders performance. What he struggles to explain is the importance of a properly tuned exhaust system that takes advantage of exhaust pressure pulses creating negative pressure behind them to help evacuate the cylinder of spent gases. Header diameter and length are the important players with this. That’s it. Once the exhaust flow enters the cat’s the dynamic is lost, hence the reason mod’s after the cat do nothing to performance.

[@thomaswilson8022]

Back pressure is a myth, and it's been proven many times that a motor doesn't need back pressure. I'm also a mechanic

[@SkunkieDesignsElectronics]

I worked on race cars and HiPo street cars for decades. 100% correct a motor does not need back pressure, total BS myth.

[@thomaswilson8022]

@Skunkie Designs Electronics it's videos like this that caused me to drop my sub and move on to other creators. Damn shame too since I'm in NC and would have really liked to support a local

[@NoNegotiations]

You dont need it if you properly tune it. You start removing with high end cars, you do feel less torque at low end. Again, that why you need a tune.

[@tr3ynag4ta]

I was gonna say too, if thats the case then you prolly needa get a tune for it to accommodate for the "new" exhaust system setup, since its made a certain way and programmed from the factory.

[@2dudescamp]

Okay, just to add to the back pressure understanding, it’s not a matter of need. The engine definitely does not need it. Back pressure is in fact bad for engine performance. What this guy was struggling to explain is pressure pulses from combustion being used to help evacuate burnt gases from the cylinders. That requires understanding fluid dynamics to “tune” the exhaust (correct header length and diameter). Changing headers can improve or worsen this, either way it also requires tuning the pcm to correctly adjust a/f and spark to match the changes.

[@NJ_Scat_Hemi_Orange]

I deleted mid-mufflers and rear resonators and installed two vacuum controlled valved combo muffler/resonators in the rear resonator location with 5 inch carven tips. Also recently locked actuators open with the MFER-1. So now i can fully open and close valves which you cannot do on any cat-back system.

[@CPhase2]

Good info. I've been going back and forth on a mid-muffler delete. Given that they are illegal, wouldn't pass inspection, and impact resale value, I'm more inclined to do what I did on my old HEMI - get a Magnaflow or Corsa Cat-Back system. The difference is maybe $600-$1,000.

[@erichaley6776]

I have a 2021 Mustang GT with the 5.0L Coyote V8. I’m running a Ford Performance X-pipe and Borla Mufflers! The car sounds amazing especially with the manual transmission with rev matching down shift! And yes I can tell the difference in better hp/torque! I’m not a Dodge fan but I’m sure they would benefit from an X pipe and Cat back system as well! I’m a Ford and Chevy guy so when someone tells you that you need back pressure politely laugh and go to another shop

[@ChrisJohansen-g1p]

Anything behind the converters doesn't require tuning. Do what sounds good to you.

[@christianarmoryworks]

I cut the mids off my 2020 392. Nothing any different with tq or hp. Still hits 515-520 HP at 6400 rpm

Remove resistance, (mufflers) reduce back pressure slightly. Lower end losses a bit, upper end gains. There is such a thing as back pressure. Don't let ill informed people tell you otherwise.

[@UnkRCP]

if cars needed back pressure they would be on top fuel dragsters and funnies. Boosted cars need the most, least restrictive exhaust gas pressures to maximize efficiency. N/A cars need proper pipe sizing to effectively "scavenge" exhaust gases to pull them through and through. back pressure does non of that.

[@djcopeland2090]

Chris is a genius bro!

[@h.rivera4726]

All scats need is the active exhaust to stay open. Quiet when you're not romping on it and loud when you want it. These kits are for sale and are easy to install.

[@williamrose7184]

The active exhaust does that just change your drive mode. The whole point of having active exhaust it, so it can be quiet when you want it to be. If you want it to be loud all the time just drive around in sport mode or track mode the way the cars meant to be driven.

[@TENNSUMITSUMA]

My question is why remove something that was designed, by the engineers (plural), to be there?! It's not bmw were talking about where they use 100 nuts and bolts for what could do! Unless you're going to do a full retune after adding/removing something, maybe the engineers (plural) know what they're doing more than you do!

[@crripper9770]

messing with the exhaust near the engine like the cats will change the power characteristics like mentioned lose some down low but gain power up top and such will be different with every car new or old, engine type and size, forced induction or NA, and how the ECU reacts and either pulls timing or does some other safety measure that plays a big factor and really anything past the cats is just a restriction and will make more power

[@kingtuck9274]

Did a suitcase Muffler delete on my Charger awhile back and I lost some Torque off the line. Never again.

[@trentonwitting5963]

And that’s why I went with corsa!

[@Stage2_392]

So question if i wanted to do an aftermarket exhaust it doesnt have 4 mufflers does it. Exhaust after the midpipes do absolutely nothing. But add more sound thats it. 😂.

[@jayt2038]

Bro back pressure is bad for engines, it’s called exhaust scavenging… if your exhaust pipe diameter is too big or if you have a restrictive exhaust(meaning your exhaust creates back pressure) your car can’t expel all the combusted gas when the exhaust valve opens… so that residual exhaust in the cylinder lowers your Air fuel ratio causing that lost of power in low rpm… these cars have X-Pipes to aid with scavenging so mid muffler delete does not affect the performance of these cars at all

[@Kc2Heatz]

They don’t mind a little power loss for some added sound. I thought you just had to tune it once you do the delete

[@RagingXiioo]

Only needs tune for straight pipe to either remove cel or get a simulator which is very cheap.

When I bought my 1st red 2015 Hellcat the previous owner had did this hack job on the car and I quickly put some Mufflers on it and the car ran and sounded much better. I could feel the added low end torque increase with the mufflers on the car and it wasn't making all those popping sounds and etc. This guy is definitely telling it like it is.👍
