does anybody know how good our muffler systems are. I just got done reading the article on the steeda system on a 01 gt...and they got 10 hp to the wheels and 10 ft/lbs. that was with the whole cat back system, 2 1/2 inch mandrel bent tubes etc. I think their mufflers are borlas right? Think there is that much improvement in our systems? how much of that hp increase do you think is due to the muffler efficiency of borla and how much is due to the better tubing?

Our Exhaust is built for Ford by Arvin. Its 2.5" stainless steel. The only advantage discernable advantage to replacing the system is to get a different sound. I doubt that there is much power being lost in the cat-back. (In other words, save your money for some LTHs).

Stangnet.com got an additional 8hp by replacing the stock h-pipe with a Mac Pro Chamber on their project Bullitt. :smile:
