3 days ago i saw a video of an M3 and e39M5 with the muffler delete and fell in love with the sound. This morning i woke up with nothing on my agenda and thought I'd get my mufflers chopped out just to have something to do. I was bored, it was fun, and... well... everything turned out great. The mufflers were deleted and i'm still running true dual on each side. The sound is better than i thought it would be. Sounds like E-race but a bit louder. Shifts aren't as hard either. ([tic tac commercial]) "I'd Recommend It".


Update: The answer to this mod is... don't do it. It sounds good at low RPM's but whistles up high a bit. I added resonators to the space where the pipe was and now it sounds like a vacuum at high rpm's, lol. I can't provide sound clips but here's what it looks like.

 

i will be doing this to my car in the next week. Hopefully it wont be crazy loud and raspy. Get a sound clip so we can hear it.

 

that is probably ok for sound, but what about power loss?

 

what exactly did you do? mufflers removed and replaced with pipe? did you do it yourself or have a shop cut and weld? will this affect the warranty? how loud is your car now? I want my M6 a little more aggressive, but still want to hear my stereo and use the phone. Thanks. sound clip?

 

you can get Eisenmann Sport Exhaust not that loud compared to the setup I want to run Race with no cats

 

I may just add the hks mufflers in about 2 weeks

 

hks makes mufflers for bmw? Pipes look good on the car though.

 

Nah, they don't. It'll be a custom setup. HKS carbon/ti muffler, X-PIPE, maybe some hi-flow cats if i can get around the CEL. I just love puzzles and with this, one has been created
