I had Kyle (KB) build me an all stainless kit with an upgraded downpipe too. Both of those requests were a little additional cash but I think it was well worth it. He took the time to answer all of my trivial questions and built me a quality kit fast! I really like that his downpipe is a two piece design because it makes the install/removal a lot easier. I can easily take it off myself which comes in handy when you need the extra space to change your plugs.

Rick makes some Trick kits as well. My brother bought one of his kits used so its probably been ran over 6 years without issue. His new cast manifolds are pretty sweet too.
