slp loudmouth resonators??? so right now i have an 06 grand prix gxp. i had the u bend replaced with a peice that isnt bent so its less restrictive. i had the stock resonator removed, and cut the mufflers off. so im left with a catted straight pipe. with stock exhaust size im getting bigger pipe too go from the cat out too tips. however my question is i have wanted too order an slp loudmouth resonator... what will it do from the set up i have now?? any info or heads up will be appreciated. its loud right now at idle semi loud at wot. but its dumped.. id like too run it out the back with an slp lm, maybe midway through the exhaust.
