Description:

BORLA® Boomers are full-blown, high-tech, dyno and race-proven mufflers for the street or track. These eye-popping, fully polished, T-304 stainless steel mufflers feature integrated polished tips, and utilize BORLA®'s patented race-winning technology for improved exhaust flow. In addition to adding head-turning sound, they also add a modest boost in horsepower. They utilize 100% welded construction for strength. High-temperature continuous-filament fiber (CFF) acoustic material for sound control. Natural mill finish can be brushed or polished prior to installation. This muffler features a 4" fully polished tip. Available in a variety of universal-fit styles, BORLA® Boomers are made in the USA from aircraft-grade high-quality T-304 austenitic stainless steel and include a Million-Mile Warranty.
