Headers 6/1 American Racing style 3 inch from F-1 Steel 304 (ask about it and you'll know) and downpipe with it, of course, guaranteed, no leaks or previous welding. Fox muffler, double valve, meaning forget about air and sound coming out when it's closed. And when you open it, Fox is known for its melody, and of course, it's guaranteed, no welding or leaks. I bought them for 2850. Selling for a fixed price of 2000, reasonably negotiable (please only serious buyers contact).
