thanks dude . yourll have been a lot of help .

now when i go to order my hooker . this the thing my exhuast guy duplicated my stock piping after the cat-back but with a 3 inch pipe . every bend is the same . just 3 inch . now what offset muffler will i need , the center on both sides . and i have a y pipe at the end of the 3 inch with 2 2.5's coming out of it for my tips . would it be better to get a single in and out 3 inch muffler or the 3 inch in and dual out one and cut off the y pipe thats on it . which is the better route to go any diff in power or sound with either one ?

 

i would go for a 3" single in and out muffler. pick a muffler with a straight througu design.
