Exhaust question???
I took my exhaust off today to get my tranny out to rebuild it and swap out my clutch and noticed that right below the headers there are a set of cats, then about a foot back theres another set of cats, and then the mufflers....Whats the point in 4 cats? can i take a pair of them off to make it louder?

get an off road h-pipe and eliminate them all, then it will sound great!
