STILLEN doesn't simply take a car or truck, figure out the piping route and slap a muffler on the end.  STILLEN puts countless hours of R&D, dyno time, and trial and error to create not only one of the best looking and best fitting exhaust systems on the market, but also one that outperforms them all!  STILLEN carefully tests systems to determine the best piping diameter to make the most power through the whole RPM band, the proper muffler to bring out the awesome sound of the motor, and the best quality piping to ensure it lasts a lifetime.  

Redline360 is an authorized STILLEN dealer, so when you purchase your exhaust from us, STILLEN will honor their lifetime warranty. 

Proudly made in the USA.
