Im looking at a 4 inch Mufflex exhaust from an LS1. I dont see any difference in path design, but Ive heard it won meet up exactly on my LT1.

Im going to need a new y-pipe and intermediate pipe so I guess it doesnt matter, just wondering.

 

Just go to a go muffler shop and they can bend the pipe to fit for you for under $30 bucks, why buy all the expensive off rode y-pipes???

 

I just used this y-pipe because it came with the headers. Its crushed bent instead of mandrel bent and it doesnt meet exactly parallel with the headers, causing exhaust leaks.
