Ypipes and catbacks
I just purchased a head and cam Pkg from texas speed(see sig), and cant wait to get it on, but I will never realize its full potential in cali because Im restricted to stock manifolds, question is would a random tech ypipe with high flow cats(CARB legal) and a magnaflow cat back free up some flow and give better numbers? Or should I just stick to stock and my flowmaster cat back?
