I had them install a full SW setup last week--headers and duals. they were great. I met the owner and got a tour and as a successful business owner myself I can say that they get it.
Their shop is great, they have the engineering knowledge to solve most anything, and their focus is spot on.
they do full custom and what they call mild to wild with several packages they manufacture in house.
ask for Scott or Josh. both great guys...
