SuperCharged M3 Exhaust

[Vibein]

What exhaust system are you running on your SC M3?

Wondering if it is worth going for a larger supersprint system then the 63.5 diameter on offer.

The full 63.5 barely fits as is, especially at the dual pipe section 2. I'd be surprised if a larger system clears the heat shield near the FCAB, the V-brace and rear axle.

I believe the only headers ever specifically designed for SC applications were offered by RMS (Race Marque Systems) A few years back. It had oversized primaries and collectors to increase airflow. RMS never had the greatest rep, and I do recall there were some fitment issues. Good luck trying to find a set now tho, as far as I know they are no longer manufactured.

i've been wondering if there would be benefit in changing to a larger exhaust system (e.g. BW 3.5") for a supercharged car. Mine is currently stock euro everything and a rogue el diablo section 3.

Can probably be sourced by Castro motorsports. The owner use to be apart of RMS when they were first founded.

I tried many setups. I'm in LOVE with the status gruppe scorza mufflers. It's a bit louder than stock but what a sound !!!!!
