I demoed one of those Thunder Alley or Valley exhaust systems on my 2000 426 on Saturday (11-3) out at Elsinore. Holy crap what a pipe! I want one, wish I woulda had my check book!! But I lost the guys card! Did anybody else out there try one? If ya did, did you get a phone number for the guy? That pipe was so much better than my T-4 white bros. pipe I couldnt hardly believe it. I just about looped it out in 3rd gear! Awesome just awesome. If you can help me with a number for that guy Id buy ya a beer.
