I've been looking for a light weight front section (w/ secondary cat delete) as well, but all the products available on the market are very expensive...


That's right, front end will require cutting between the 1st and 2nd cats, cutting is done 4-6 inches above the secondary cat, then welding needs to be done. The opposite end will be a bolt on and off to the stock muffler, no cutting or welding require. This x-pipe replace the secondary cat and the resonator. Hope this clear things a little, it should be a simple process, and can be done done at a good mechanic shop.
