See my sig.

I am running completely catless and have not had issues, but retaining the stock muffler would not be good. I chose to purchase an oem Eisenman built PSE and the sound is really nice. That version will fit up to MY '02.

As far as aftermarket headers, I chose Turbowerx and they deliver results. You need to find a good indy mechanic and he will know how to keep your O2 sensors from triggering a CEL. It can be done.

I have had only one CEL after having my setup for a year. I purchased the Durametric cable, downloaded 6.0 software and it was gone in seconds..

To get good results, you need to take the plunge and do all exhaust replacement from the headers to the muffler. Just don't buy junk or you will not have a good experience...

All in all, I have 800 in headers, 500 for the Fabspeed pipes, and I think around 13-1400 in the PSE. Bought it new off Ebay a long time ago. They sometimes surface...If not, they can be had close to 3k now, but other manufacturer's like Fabspeed make a good muffler.

I have not run my car on a dyno, but can tell you that additional power is being made. Sound is very nice too.
