My locale Corvette club met in the Bay Area last month and they had the clubs highly regarded mechanic super tuner and he made a claim that frustrated me. "Flowmasters don't make power!" I really could not argue with him because I never dynoed my LT4 after I got the Flowmasters. I can clearly feel a difference especially since I removed the resonator. But my question is who went out and tested all the major brands Corsa. Borla, Power Effects, and Flowmaster? I mean same car same dyno? That's the only way to know the difference. I find it hard to beleive I wasted my money four years ago. Scott
