Best Full Exhaust System

DOMs335D · 03-20-2022, 06:21 PM

Hi everyone,
I was hoping I could get your help. I'm thinking of getting a full exhaust system (Downpipe + midpipe + rear pipe & box) for the M2, and I was hoping I could get a few suggestions. I've had the following three setups, and I'm not really in love with any.
- During Euro delivery it was all stock - too quiet
- Once it landed, they installed MPS - famous drone right at highway speeds, but I liked the overall volume and sound
- now VRSF catless downpipe + MPS - drone x1000, but very fun on track

What I'm hoping is something with less drone while being more efficient than the stock setup at reducing backpressure and pulling some of the heat away. This is for a pre-LCI non comp.

Appreciate any feedback!
Thanks

Have you got rid of ASD? Once I installed the ASD bypass harness all my drone disappeared. I have the M Performance exhaust.

Some people prefer just a sport cat downpipe, and nothing else. Personal preference.

VRSF catless with stock exhaust and tinkering with pops etc with BM3 is the sweet spot for me.

I’m in that camp. Catted downpipe with stock exhaust and no ASD. Deeper sound with just the right volume for me. Minimal drone. Closing the exhaust valves helps.

Hey guys thanks for the feedback. I'm going to try with the by-pass harness. I have JB4 right now, but I was going to add a backend flash to turn the coldstart sequence off, it makes it extra obnoxious.

Valves are now pretty much always closed, aside from some early morning mountain drives with windows down
