I am trying to build a 3 inch exhaust for my firebird, and have decided to go with the hooker 2055, catco 9118 cat and hooker 3 in. cat back system. I have purchased the catco 9118 catalytic converter and the Hooker cat back system. If anyone has this system or something similar, and could help me out that would be great! The converter connects to the Intermediate pipe with two sliding plates that encircle each side. It appears two bolts would go through both plates to hold the two pipes together. I was not given bolts with either kit and do not know what size or grade I should buy. Also according to the picture on the website I bought the converter from, it looks like there might be a gasket or spacer that goes between the two plates. Neither my converter nor my Cat back system came with this gasket either. So if someone is using this setup and knows there is something that goes between the plates please let me know.

Thanks ahead of time

There is no gasket between them. You can just reuse the bolts that you have now. If you want or need new ones and no one on here knows you could just to to an exhaust shop and ask them.
