I'm saving my money for a new tranny, 3000tc, and 3.73s. I got the RAISS, Tri-Y's, no cats, $215 Catback w/ x-pipe, Garys big 3 upgrade, and Hacks trunk kit. With the stock manifolds/cats I had some drone and I expected it to be worse with the Tri-Y's and not cats but it actually went away. The Summits sound real good, but theyre really quiet. You can't hear the nice sound they put out at all in the car.
