Mark, I asked this very question awhile ago and the general consensus was Doug's or TTI's but as you know the draw back is the price. I went through a set of hedmans and a set of blackjacks both of which I squished going over speed bumps. I can't speak for the power increase as my car never had stock exhaust since I bought it. The TTI's are a pretty nice fit and access to plugs, starter motor etc is excellent. Are they worth it??? Hmmmm, that's arguable I suppose.
