Ken here in UTAH. I dont know what you are currently using, but I would go to Bassani Equal length ceramic coated headers with either the "off road" pipe, Or the "cat pipe", that Bassani sells. Of all the systems I've seen, I reall think they work the best for our Gen 1's. Use Flowmaster 2 chamber muff's(There will probably be someone that will disagree on that). Seriously the flomasters sound and work great. Use 2 1/2 exhaust from the muffs back. Most reputable exhaust company's in your area should be able to accomodate you. KEN |
