Aye ive got a Silverline muffler on my tC right now..I can tell it helped alot on the takeoff but some ppl told me that i should get the TRD or the Injen...can any1 tell me how good the trd and injen are..

 

I dont mean to be mean but there are 103 pages in the Drivetrain and Power forum.. under the banner at the top on the left side is a red search button.. click it and type trd exhaust and look at results.. or type injen exhaust and look at those results.. there has to be a ton of posts about this already =)

 

uhh.. you can tell from a butt dyno that an exhaust gives better performance...?

and for the rest.. yeah.. search please...
