I am now looking into my next mod and was just wondering which one will give be the biggest noticable power increase. A pacsetter cat back with a test pipe, or afx underdrive pully? Also where is the best place to purchase those things? Thanks guys you've all been alot of help.

i would have to go with the udp.. my exhaust was my first mod a long while back.. it didnt give that much in performance gains, but the looks and sound was well worth it.. but the udp to me felt like a bigger gain.. get them from either howell or ptunning.

The UDP from Howell Automotive will net you the better performance gain. Truthfully, I didn't feel any hp difference with an exhaust system.

what he said

Ill jump on this bandwagon. Although I did feel a slight performance gain with the exhaust, the UDP yielded a greater gain. The is one of the cheaper mods compared to the hp gain you will receive.

Yeah what they said...lol If your going for bang for the buck then the UDP is the way to go. The exhaust is nice and makes it sound alot better, but really at most you might only get a minimal HP gain out of it. The UDP costs about the same as the Pacesetter catback so I would have to go with the UDP to if you only have money for one or the other.

haha just put on my catback and I think it gave me a good gain im happy with it plus it sounds better then just the muffler also i didnt install my udp yet tues. :D its going on so i will let you know i am expecting more from the pulley to tell you the truthbut get both if you have the money i hate stock exhaust looks plus the exhaust you can do your self its a bolt and hang on i would take the udp somewhere...

UDP. Also, I know you didn't mention it, but motor mount inserts are a good mod as well.
