Exhaust System for 1970 Corvette 454 AutoTrans
Its difficult to find quality hardware and even harder to find excellent Customer Service, but I did when I chose Stainless Works to build a new exhaust system for my 1970 Stock 454 Corvette. Fit and Function was beyond my expectations and as a rocket scientist mine are hard to meet, much less beat. Thank You Stainless Works for taking care of my ride!
