i just had my viper dynoed today so i now know how much of a difference my exhaust mod's made compared to stock. stock my car made 421 rwhp and 452 rwtq. i installed belanger headers, random tech cats and 3 inch corsa cat back. my viper now dyno's 452 rwhp and 495 rwtq. this is a 31 rwhp gain and a 43 rwtq gain. i am satisfied. my next hp mod will be high ratio t&d roller rockers.
