ssviper - I don't have and never will have pipes on my viper. THere are ways to get as good of performance with much wider powerband, without the jetting hassles, and stock sound. My mtn viper looks and sounds stock and will run with any shorttrack nonboosted machine. NOt my doing though, the genius work was done by a pro. Not any cheaper than pipes, but much more consistent and I unless all conditions are PEFECT for their setup, I can beat virtually any triple piped viper. No its not turbo or nitrous or any of that. Pm me if interested. have a great weekend.
