What gaskets do I need????
 

So I'm replacing my factory header with a borla, and my factory catback with a perrin. What gaskets do I need to replace? I've found I'll need 2 exhaust manifold gaskets and maybe 3 2.5" exhaust gaskets?
Any advice is appreciated. Thanks!

Get GrimmSpeed exhaust manifold gaskets. They're just better.

Perrin catback should come with gaskets unless you're buying used. It uses v-band clamps so the only gasket you'll need is the one from the stock cat to the mid-pipe connection which comes with the exhaust from Perrin.

For the header install, I would use GrimmSpeed manifold gaskets as recommended above and you'll need 1 additional 2.5" gasket for the header to OP connection.
