after reading a post on gasket replacement, I remembered that I installed my greddy evo 2 exhaust I got used with gaskets I got from Autozone. Its very hard to find gaskets of any large size at your local stores but check for chevy silverado truck gaskets. They only cost about 1.50 each or a little more, less than if ordered from greddy etc. They seal excellent!

Warning: You will have to drive to a couple Autozones etc. because they only stock 1-2 per store. I luckily had 4 within a 10 mile radius.

I figured I'd share this for any guys doin any DIY exhausts fixes or installes.
