Ebay's got full headers-back for like $250, but there are no cats and it might sound really loud and raspy. Otherwise check out junk yards for one that's in better shape than yours.

 

Thanks for the reply. Really what I'm looking for (if it exists) is a stock kit I could buy, then take to my mechanic for him to install.

 

You can buy one, it's just prohibitvely expensive. If it's not too bad off maybe it can be repaired? May ought to just take it to some shops and get some estimates.

 

The most expensive part will be the headers and downpipe because it has a welded in catalytic converter. I replaced a bad cat on my 3g recently and my only oem replacement option was about $375 for the cat + downpipe. I bought a $100 magnaflow weld in cat and it works just fine. My rust problem was only major near the muffler, so I replaced it with a catback.

 

Just get a used OEM exhaust that's in good condition. I bought an OEM exhaust that only had 5000 miles of use for $20.

If you're getting a C5 don't put a rice burner exhaust on your Eclipse.

 

I've seen some decent-looking ones at junk yards but it's sometimes tough to find them at junk yards that haven't had the cats cut out. Your precats should be ok, but I know the y-pipe, especially the flex pipe, like to rust out.

Maybe you can find someone on here or craigslist who's parting out a stock(ish) Eclipse that can give you a deal, or replaced their exhaust and have the stock shit laying around taking up space.
