There is a lot of crap out there. I would avoid the 'OEM' Bosal stuff and that other black OEM stuff on ebay. Complete Junk.
I ended up with genuine Subaru midpipe and mufflers. Not cheap but it fit right, will last, looks right and is QUIET!. I'm a little mental about keeping the car 100% factory anyway.
The original stuff I took off went thru 15 MN winters and 217k miles. Probably could've lasted another 5 years.
