Stock x5m/x6m mid pipes
compared to m5/m6 mid pipes
I've recently added down pipes and the exhaust note is a bit louder but im looking for a bit more w/out changing out the stock muffler.
I've heard a stock m5/m6 exhaust and its pretty aggressive but not too much. Upon reviewing both the x5m and m5 exhaust i realized the x5m has an additional muffler and possibly cat on the mid pipes. To compare on a E90/92 m3 the car also comes w/ 4 cats, 2 primary and 2 which are normally replaced with X pipes for 2ndary cat removal which increases exhaust note but also performance.

I may start replacing one at a time to see what a good compromise is. Anyone else mod their mid pipes ? any decent exhaust shop should be able to do it for a reasonable price
