Anyone know any good shops that do some custom fab? I need things like intercooler piping, downpipes, exhaust manifolds, etc made. I want good price but of course, good quality. Also, if they use materials like 321 stainless steel and 6061 aluminum is a plus. And I prefer local to Pasadena, 626 area code, but I'm willing to travel around SoCal for a good shop. Please let me know if you guys know any, thanks!
