As of now I have crawford headers on the way, and AAM test pipes. I'm curious if those two components alone are better than replacing the entire exhaust, would keeping the stock cat-back in place give me better performance or would adding a cat-back with the headers and tp's give me the most power? I was looking towards borla true dual.

 

Depends. TPs and headers will most deffinatly make your car louder and meaner sounding. I would keep stock cat back untill you hear what its like. A cat-back for a non-FI car won't get you much more HP if any (especially without a dyno tune) All a catback will do is change the sound, make it louder, and looks better. Up to you there, chief.

 

Get the non-resonated JIC single and just drive down your street on the rev limiter.

Seriously...i like the HKS but don't have the money, it is quiet when driving around like a normal person and opens up when you get on it.

 

im debating between the HKS knock off and the topspeed pro N1...cant make up my mind..

any other exhausts for fairly cheap?im looking for some other mods so i really dont want to pay 12-1400 for the HKS

 

Typically - you should do exhaust from the rear of the car forward, not the front back. Feeing up flow at the front, without modifying the back will hurt performance overall - in some combination. Pulse scavenging will be hampered, as the system will not handle the extra flow very well.

With that said - many people do it this way. For sound purposes, not an overall power plan for the car. The top 3 true duals are only a matter of 3-5 HP apart from each other, but have dramatically different sound between them. HKS, Stillen and Fast Intentions. The Fast Intentions and Stillen use 2 1/2" pipe - where the HKS uses 2 1/4" pipe. If your going to open flow even more, by adding headers and cats, the 2 1/2" systems are what you will want - unless you go with a 3" single with great Y-pipe.
