Description BORLA 40057 Thumper - 2.25" Inlet Pipe - Single 4" Round Tip - Boomer Muffler
BORLA Boomers are high-tech, dyno and race-proven mufflers designed for both street and track use. These fully polished T-304 stainless steel mufflers feature integrated polished tips and utilize BORLA's patented technology for improved exhaust flow.
In addition to producing a distinctive sound, they provide a modest increase in horsepower. The mufflers use 100% welded construction for added strength and high-temperature continuous-filament fiber acoustic material for sound control. The natural mill finish can be brushed or polished before installation.
