I don't plan on getting a header, since I have a turbo. Right now I just need a cheap cat back.not a bad exhaust, especially for the $$. good flow, all mandrel bent.
the SS ones seem to be more popular and I believe that someone does make them, but i don't know who. However, they're 3X the $ for 2X the lifespan of the piping. Only issue is that the down pipe for the PS exhaust hangs a bit low if you get the headers, and some people have had issues trying to hook up the EGR pipe to the headers. The muffler IMO is wonderful, i grew up with the Monza exhausts on older British sports cars and some Italian ones. Personally i dislike the spud cannons that seem to be so popular. Unfortunately, the guts to the PS muffler are also made out of mild steel and will be gone in about 5 years, and they don't sell the mufflers as a separate unit. Either you'll have to buy the whole cat back system again, or source another muffler to attach.
