Taylor Sims at Dallas Performance just finished doing a set of pipes with Howe Racing mufflers and Howe merge collectors. Very pleased with his work, nice young guy, he did most of the header & pipe work at Keith Craft and decided to go out on his own. 972.494.5343. His shop is in Garland at 3108 Benton St., 75042.
He isn't cheap, but the best never is, he has a new in ground DynaJet dyno so you can tune your car and get before and after RWH reading. But if you want outstanding work he's the guy and also has several neat projects underway at his shop.
