So did some searching and before I laugh and talk smack to a friend wanted to get everyones opinion, good or bad.
My friend recently bought the SAME car as me (07 BMW 335i Sedan), and he was talking bout modifying the exhaust. Tell me this will NOT work or will sound like sh#$! I have a night of drinks on it!
He wants to cut off his mufflers in the back and have a CUSTOM exhaust shop weld/mount these on. (BELOW)
1st ?, has anyone done this, 2nd ?, wont this set off the computer? 3rd ?, Is there even enough room?, and lastly, will this even sound good, or help performance?
