Looking For Lightweight Sound Control Without Sacrificing Horsepower?
We Have Your Light Weight Race Mufflers That Are
Dyno and Track Tested with No Power Losses. Extreme mufflers will meet or exceed your race track or street requirements.
ARE YOUR "RACE MUFFLERS" ROBBING HORSEPOWER?
As we all know, the most expensive horsepower is that last 20 to 50 hp. Why give it away by installing just any muffler?
Just because the box claims to be a high-flow or race muffler, you may still be losing 15 to 30 horsepower with the installation of just any "race muffler".
After years of development and track testing, Extreme Mufflers brings you a lightweight race muffler built in the USA that will meet track dB requirements without giving up the horsepower you worked so hard to develop.
Check out the independently done dyno test charts on our race mufflers from well-known engine builders.
"...with your mufflers, my car went .15 faster! .10 in the 60ft. ..."
