The Viper Pipes muffler has been purpose built to increase the performance of your motorcycle powered race car. The muffler has been designed to fit over a 1-3/4” diameter header or tail pipe and features a welded tab for easy installation.
After spending time on the dyno with several different mufflers the VPR’s design won out producing more horsepower than the competition.
The Viper Pipes muffler is purpose built for racing including lightning sprints, mini sprints, dwarf cars, modified midgets, mod-lites, TQ midgets and more. Although we can’t reveal all the Viper’s secrets, the perforated core that transitions from 2 inches to 2-1/2 inches at the outlet is one of the big reasons. You will also notice that the end caps are shaped different than the competition–it’s all about creating the proper balance of airflow and scavenging to maximize performance across the entire power band. It is also designed to meet most tracks decibel (db requirements) rules.
The VPR is constructed of mild steel including a perforated core and steel packing. The core is encased in 4″ diameter 16 gauge aluminum core that is held on with high quality stainless steel rivets. The muffler comes with a stainless steel barrel clamp that is specially designed to get the job done. Standard worm gear clamps just don’t perform.
