Videos of CP-E Full Turboback Exhaust on 135i and Challenge Exhaust on M3

[SpacE82]

Hey guys, last weekend my brother, who works for Challenge USA, made a video for the Challenge M3 and my car's exhaust systems, so here are the final products. I have a full CP-E exhaust with catless downpipes. You can kinda hear a nasty exhaust leak that CP-E hasn't really been helpful about fixing, but thats a whole separate thread that I dont feel like making.

The other video is of the Challenge/GT Motoring M3 with the Challenge catback exhaust. Greg of Challenge/GT Motoring is planning on making a catback exhaust system the 135i. If the exhaust on the M3 is any indication, it is likely that the exhaust for the 1er will sound amazing and be of great quality! If we can get enough interest here on the forum, it may make him develop it sooner! So any interest!? Enjoy the vids!

Very interesting, it seems to have a resonator or a muffler???

Yeah, sorry i forgot to mention, my CP-E exhaust has the resonator and the stealth pipe and the M3 has a muffler and a catless rear x-pipe!

It is insane! The car sounds awesome, it's loud, but not TOO loud. I always had him drive in front of my so i could hear it while we were driving haha. I can't wait for him to make exhaust for the 135!
