Exhaust Note

x35250 · 12-12-2021, 03:49 PM

What options are available for a deeper and slightly louder exhaust note from inside the cabin OTHER THAN a downpipe and tune?

Currently, my 2013 F10 M5 has a custom 93 octane tune thru BM3, a Meisterschraft valvetronic catback exhaust (stock downpipe), and 2-step colder plugs. Everything else is stock. The tuner will no longer code out CELs even with a catted downpipe.

Research so far...

1. Soul Performance resonated muffler bypass
2. Fabspeed or Turner muffler deletes
3. Cut muffler out of the Meisterschraft unit and have a straight pipe welded on (hoping to keep the valvetronic function)
4.Any others?

I am considering the CTS Turbo catted downpipe with a new custom tune, but that seems a bit pricey for an improvement in sound. I'm completely happy with my current power level especially on a stock transmission. There's gotta be something I can do!

X crossover pipe seems to be popular with the V8 M3 fans.
