F80 M3 / F82 M4 exhaust resonator delete and straight pipes

You want a nice smooth path for the exhaust gases to get out as fast as possible. An x-pipe would introduce turbulence and create back pressure. An x-pipe is really only useful in a NA engine because you can take advantage of the scavenging effect on the exhaust pulses. The turbine blades cancel out these pulses and what you want is to a smooth path on the way out.

Thank you, please come again!

I have actually driven 2 variants of the new Jag convertible (same engines as the new coupe) and they both sounded amazing. Problem with the rest of the car is that it's more of a GT than anything in terms of the ride, shifting, etc. It's really meant for the older driver who wants a 2-seater but isn't looking for a proper sports car (ie. Cayman/Boxster). Anyone who is seriously considering an M3/M4 won't be the right buyer for the Jag and vice-versa when you consider the sport vs GT characters and 2 seat difference between the cars.

But, in all fairness, comparing almost any car to the new Jag in terms of exhaust sounds is a losing proposition, as the exhaust is probably the BEST aspect to the new Jag from a fun to drive perspective.

All of that being said, I REALLY hope some new owners try some more mods so we can find a mod and/or aftermarket exhaust that sounds good on the new M3/M4, as my E93 M3 with the OEM Exhaust Mod (non-perforated) puts a smile on my face everytime I drive because of the exhaust sound. And I'm concerned that the new M3/M4 won't do the same based on these preliminary reviews...

OK great, didn't knew that! Thanks.

the jag is one of those cars IMO. where the engine/sound is the selling point of the car.

wait couple of years and you will have that Jag for 15K, they depreciate as quickly as britney spears

Untrue, it SMOOTHS turbulence and equals flow.

No drone at all. This mod with an AR catted DP will sound awesome! Btw that's my next mod.

F82: "Listen to how great my turbodized Sixer sounds...!"

[F82 revs and farts his ass off]

E92:

"Look kid, this is a real mens engine sound:"

Any check engine light ?

[nakata06]

Dear Members, are there any power gains from removing the resonator or purely for sound purposes? Is the resonator restrictive?

Thanks
