Increase your truck's horsepower and get the bold exhaust note 
you're after with Dynomax performance exhaust systems.

You can easlily pay more than double for the perhaps better
 known brands, (and we sell them) but you will not get a higher 
quality or better-sounding system than the DynoMax 
performance exaust!

DynoMax® VT™ mufflers offer a revolutionary, high-flow straight-through stainless steel performance muffler that controls irritating drone, while ensuring maximum performance. To provide Drone-Free Performance™, DynoMax® Valve Technology mufflers feature an exclusive, precisely calibrated internal valve,  that redirects exhaust flow during cruising conditions.  Floor the gas, and the valve will automatically adjust for maximum exhaust flow, delivering on-demand performance and a deep, throaty drone-free sound.

HEAR THE SOUNDS OF DYNOMAX: /sound.mp3 but read below first:

For the best results we HIGHLY recommend using a good set of headphones or better than built-in computer speakers. Muffler sound is all about BASS. Cell phones and built-in computer speakers will not give you the true experience of the Muffler sound.
