DYNO-TESTED TO MAKE THE BEST HP ON THE MARKET  
We've tested this pipe over and over—through private-label vendors, track riders, and dune riders. Hands down, it beats the big-name moto pipes and is the best choice for performance mods. We've been refining this pipe since 1997 with slight tweaks along the way finding little more. Since we are cone made pipes not stuck with stamp made pipes. Used on many personal builds, customer bikes, and still today, it continues to outperform the rest!
