i have a 1995 5.0 and im lookin for a loudest muffler without running straight headers. Running flowmaster 40s single chambers w/o cats. not really liking the sound. would getting a bigger diameter pipe and some headers make it louder? Or anybody got exhaust cutouts? i've been looking at the slp loudmouth any experiences with those? thanks

 

Slp loud mouths are really loud. And sounds pretty good IMO. And I put a pypes high flow cat mid pipe on my car and that helped with sound and performance. But I'm just gonna get some longtubes and some O/R x-pipe and call it a day. Makes it a Hell of a lot louder and for performance about 18+ rwhp
