All the parts are in! The 460 rolls out of storage this Sunday. Will be making arrangements for the headers to be installed, then doing the rest myself. I will keep you all posted, I hope to have everything done within the next two weeks. Aren't tax returns great?
Everything is done and it came out great! Headers took an extra two days at the shop, nothing bad, the place had a long line.
Had to saw out the old muffler and other restrictive pieces
Replaced with three inch pipe and a thrush welded muffler, it sounds mean as hell. Will post a picture. Thank you all so much for the help, this project was so much fun to do.
