I've got stock pipes on my car, and it's got some sort of header, I don't know what kind. But I'm curious if I could or should just put in my own pipes, leave the stock pipes, or buy more pipes made by some company. I live in rural WI, so emissions are not an issue, either.

 

Borla xr1 to for presilencer and cat replacement. and a catback muffler assy of your choice.

 

Racing Beat makes great exhaust kit or HKS the only way i would go.

 

Would you say I stick with a cat, or if I can keep it out, keep it out?

 

If you have the money replace the entire exhaust system and sell the header. Then you know exactly what you have and what you are working with. Keep in mind if its something like a Pacesetter header, you'd be using a stock cat to open the 5th and 6th ports. A RacingBeat presilencer and header have enough backpressure to open the ports. So the headers maker actually has an impact. Without emissions go with a RB header, race pipe to a single muffler, buy a muffler on eBay. It'd be a full exhaust for about $400 bucks. Then just wire open the 5th and 6th ports.

 

Take a picture of the header b4 you **** can it. It may be a nice older stainless steel header. If that is the case then you just need to design your system the way you want it. Free flowign cat, or no cat at all. Presilencers, duals all the way back. User option.
