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.

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 Жыл бұрын

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.

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 Жыл бұрын

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 Жыл бұрын

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.

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

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.

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.

@jayt2038 Жыл бұрын

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
