Will this fit if my headers are both lead and connect to the passengers? And is it also doesn’t to connect by three bolts?Christopher M.Oct 10, 2024
Best Answer:Hi Christopher, I am pleased to assist you. This system is made for vehicles with a dual exhaust setup, meaning it expects the headers to connect to both sides. If your headers both lead and connect to the passenger side, you may need custom modifications to make this system fit. The Flowmaster system may not be directly compatible if you have a Y-pipe or a non-traditional setup connecting both headers to the passenger side. I suggest calling our parts specialists at 1-866-529-0412 to provide the vehicle information so we can help you look for the right part. Have a nice day!
