Ok here is my problem I bought a used off road H-pipe. Now my car sounds completely horrible. I know for sure there is a leak between the passenger side header and the H-pipe. I also seem to have one on the drivers side at the rear connection. Now all of the bolts are tight checked them and rechecked them. Just wondering what I should do it sounds like a piece of junk like this. Are there any kind of gaskets I could pick up at the parts store to put in there? Or is it time to surrender and take it to an exhaust shop?
