So, my exhaust manifold has a decent sized crack in it, definitely leaks some exhaust there. I was considering getting a header and flowmaster cat, but I dunno if I really wanna bother with all that and drop that cash, since I'm not expecting my stock 7a to really gain much other than style from it. I did pick up some "thermal weld" stuff as a quick patch, haven't tried putting it on yet tho.

thermal weld wont hold. it will crack more eventually.
