Custom G8x M3/M4 exhaust system by some guys in the UK
This video clearly shows the exhaust system from below and he does a great job explaining what they are doing and trying to achieve. I am gonna work with a local guy who does a lot of custom titanium exhausts and see if we would be willing to create a mid pipe section with an X or H pipe at an affordable price. |

The s55 m4 sounded like shit when people would put x pipes. The m performance exhaust had an h pipe that I was a fan of.
I know they're different as the s58 sounds better I think it has EL pipes out of the factory, but in general these motors sound better with H pipes than X pipes. They're too naturally high pitched to benefit from a x pipe, the h pipe helps it sound deeper Car in the vid sounds good |

Good video thanks for sharing. I deleted the primary resonator on my G82 today. Not much louder. Going back to delete the secondary cats.

Don't understand why they would put all this effort into building a new exhaust for this car "from the OPF back". If you want the car to sound good, you first gotta remove the OPFs. While there's more volume to this aftermarket setup, you can still hear how muffled the tone is as a result of the OPFs. Not to mention they decided to edit in background music during the initial startup with the new exhaust .

But on the G80, I find there's minimal sound difference between the NA and EU spec cars. Burble tune is pretty much non-existent in both region cars, and they both sound pretty muffled. That's definitely a let-down on the G8X given the engine has a naturally lovely intake sound and revs high, so it has the potential to sound very good. Definitely need to fit a proper aftermarket exhaust to do the car some justice. |
