Haha
When I had taken the secondary cats off, I was still on a completely stock exhaust, so the difference was small, but still there. Once I changed it all up as I expressed on a thread here, it was totally different. My closest friends (all car guys) have told me that my M3 sounds like an exotic. IDK what to think about that, but with that kind of motor we got, I'm not too surprised!
