it is only about 2% luder thatn stock
it is only about 2% luder thatn stock And only at higher RPM. Virtually none noticable.
I got in only because I was looking for little more rumble when idling, just like Z4 I test drove (stock), the sound that Z4 is putting out is perfect for me.
Remus on the other hand is.. well ... like I never changed the muffler at all.
Maybe it is the exhaust part that is just before the muffler is surpressing the sound that I am looking for. It looks like tha car exhaust is prepared for dual exhaust of 540 but one part of it is just blocked out and there is only one pipe going to muffler. what if I remove the "Y" looking part. will that make it little louder? Plese help me, since I do feel like I spent $400 for nothing.
