well hopefully with these flowmasters and down the road the borlas will help with sound. on my 200 t/a, i bought the slp loudmouth when i had stock headers and y-pipe with clogged cats and it sounded awsome. then i went to long tube headers and 3" y pipe with no cats and sounded like garbage, and was retarded loud. with my 2001 on the other hand, had long tubes but custom made true duals with x pipe, same concept with the mufflers like the slp just different brand and sounded f-ing mean and very loud. theres a fine line with exhuast and making it sound good, just gotta find it and tip toe that line.
