What will my car sound like with just the installation of my OBX header cuz all i got so far got new for a pretty good deal. Will i feel any difference performance. Im gonna get the Greddy Evo2 exhaust for my car and an SRI WeaponR intake. And later on a hiboost kit.
 
The primary cat is the most restrictive part of our exhaust sytems--you should get a noticeable gain replacing it with the header. I don't know what it will sound like, maybe just a little louder? Let us know when you get it on! :)
 
Well hiboost kit will get rid of the header but get an intake and exhaust too or there's no point.
 
Boost could be conceivably very far off for some people. A header is what... $250-300 or so? That's a bit of a drop in the pan when compared to the cost of going turbocharged.

I say throw the header on to tide yourself over for the time-being. Who knows how long it'll be before you can afford to go turbocharged.
 
Yea i know i got my header for 175 so i figured go for it why not its cheap and the turbo i should have this winter ready for next spring
 
Header was my first P5 mod and yes you will feel a difference. With stock exhaust it will not be loud.

I have just the header on stock exhaust - not much louder. Nice bump in performance coupled with UDP.
