My old exhaust had leaks from every joint, the cats were reading bad on my scan tool, and well... I just wanted new exhaust.. It's all re-done from the manifolds back, with a short section reused for the rear o2 sensors. Cats are $40 ebay specials, mufflers are 17" Brockman mellow tone steel packs. I plan on eventually painting the mufflers with some high temp flat black and adding some chrome tips. One side was a little off but as you can tell in the last pic I got out today, adjusted the rear hangers and got it pretty well lined out.
