thank you for posting that. Good video with good sound!

Is the 6-8 hp increase all on top end? Any mid range increase?

Just got a truck load of Ulmer Racing Edition SR Viper mufflers & headers, made by Straightline Performance, ready to ship! Call today! 605-387-2833

Muffler + 6 hp, quietest muffler that I have tested $279

Header, true merge collector, full stainless, as close to equal length as we could get it! Great upgrade on a turbo for spool. Adds 4-5 hp over stock header! $699

Header & muffler together 11 + hp, add our intake kit and you're 18 + hp gain from 5500 rpm to red line!
