The Best Race Muffler Package In Racing
Extreme Technologies is dedicated in the development of sound control without sacrificing horsepower.
After many years of development and track testing we are able to bring you the race "mufflers that will meet local track dB requirements" without giving up the horsepower you worked so hard to develop.
As we all know, the most expensive horsepower is that last 20 to 50 hp. Why give it away by installing just any muffler. Because the box claims "high flow" or "race muffler" you may still be losing 15 to 30 horsepower with the installation of just any race muffler.
