Quiet Race Series Now available for all dirtbikes


BROOKPARK, OH, June 30, 2009 – (Motor Sports Newswire) – HMF Quiet Race Series: With sound restrictions becoming stricter, there’s been an increasing demand in quiet race exhausts.  To help out this increasing demand, HMF is now offering the famous Quiet Race Series for Dirtbikes.  The Quiet Race Series is designed for racing machines and meets most sound regulations while still delivering big horse power gains. It’s available in brushed or polished aluminum and will significantly drop the weight of your bike over stock.  When compared to the MX Series exhaust with an HMF Quiet Core installed, the QRS delivers more horse power and less dB.  See the available models below for more information about your application.

Starting MSRP: $299.95

HMF Racing was founded in 1997 by Hans Luenger in Cleveland, Ohio. Hans started the company by himself in his garage building private label aftermarket performance Ducati Motorcycle exhausts for Fast By Ferracci. After refinancing his house three times between 1999 and 2002 and selling his Corvette and FZR 1000 to keep the business alive, HMF reinvented itself once again by plunging into the ATV exhaust market in late 2002. As the industry leader in customizable parts and colors, HMF Engineering, Inc. develops the highest performance exhaust systems in a variety of different series. Each series has it’s own unique attributes that makes it different from the others.
