I have a 2004 Tahoe 4.8L V8 I want a good mean sounding exhuast, but not to loud to where Im always hearing it inside the ride. Im debating between a Flowmaster 70 or 50, I heard the 40 wich sounds hella sick to me, but would I get in trouble with that? Also wondering about the magnaflow ones. Whats a good one out there? Thanks.
