Long story short I have a short BBK catted high flow x-pipe and the longtubes on my car don't fit it. It turns out they aren't even for a Mustang and are melting wires left and right. So I am buying a new set of Longtubes, and looking into Flowtech ceramics because they're super cheap and have ceramic coating. My car has no O2 sensors. They guy I bought it from took them off. What do I need, as far as sensors and extenders? I have been searching and researching and can't find definite answers. I am sooo confused. Can someone help.me out? Thanks I need to order these tonight!
