sense i have not found to many people that go from 2.5" downpipes to 3" cats and exhaust. I will have to read that link in class as im busy doing a project now ;).
Appreciate it though man. Im not forking over more cash for exhaust right yet as already have a very costly motor build and swap right now. So the 300 degree fuel rails make the 740s a drop in right i wont need anything else?
