    Cobb downpipe install.

    Hey guys, I'm getting ready to install my Cobb catted downpipe on my 2011 WRX. Is thier any reason I wouldn't be able to reuse the OEM doughnut gasket and the bellmouth-to-turbo gasket. My car only has 1700 miles on it so I'm guessing I'm good but I want some other opinoins.

    Thanks

    it's probably fine. They say you're always supposed to replace gaskets no matter what... but you're probably just fine

    I would assume you are fine as well, but as i have learned, you need to change your gaskets

    OE donut gasket is fine to reuse.

    The turbo/downpipe gasket should be pretty fine; if you want to reuse it, use something to recreate the lip that's on the gasket for a good seal. Personally, I'd rather just spend the $8 or so for a new gasket so I wouldn't have to reinstall if there was a leak (not that a leak there would be that bad).

    Id spend the $8. Trust me. Nothing more irritating than doing the install and finding a leak. Oh and keep the old setup never know when you need to go back to stock

    Thanks guys. I think I'll go ahead with the oem gaskets then. I will however order new ones in the future.
