Well it's not a y pipe, but you know what I mean....

will this gasket from RRO fit the stock exhaust ??

'Bulletproof' header gasket.

If you're like us and you run a header, chances are you've blown a header gasket and had to replace the thing. This is because the gaskets these suppliers ship you are made from cheesy paper. Forget that! This one is made from a thick flexible aluminum. It won't burn out on you after so many thousand miles. Use it, reuse it, reuse it again.... this thing will last and last and last. Better than the Energizer Bunny! Comes with nice new shiny bolts too.
