Any idea why? I have had a n63 with the same setup and that actually sounded like a v8. Has a mean growl even at idle. But the m5 doesn’t 🥲

Even at a car show revving an almost straight pipe sounds like a stock corvette lol. I miss the cammed corvette sound

Can't hear it??? Maybe hearing aids are in order? Mines the same setup and it's loud af.
What tune? My car gunshots on damn near ever shift when driving conservatively and every shift if I push it even a little. BM3 stage 2 aggressive tune, downpipes, stock midpipes/resonators, muffler delete kit, aFE Momentum intakes is my setup. And turbo spool always.
