Today I took the 68 down to the muffler shop to see what kind of shape the pipes and mufflers were in. Lets just say this. Rip it all out and start all over. Put the headers on it then went all new from there down. In the passenger side there was what looked like a gash 8-9 inches long, driver side muffler was toast, and the passenger side exhaust manifold had a hole in it. They put on enforcer 2s on there with 2 1/4 pipe. Has a nice basey tone to it. Ahh the fun of driving with no exhaust leaks
