Race-Pro 4" Slip-Ons

These novel 4-inch muffler bodies feature advanced acoustical tuning technologies for a deep rumbling sounds. 

The 4-inch round muffler front expands just aft of the steel clam shell clamp to 4.5-inches diameter.

The matte black finish on the aluminum tip is matched with the satin black finish on the laser-cut steel strap that tightly encircles 

the muffler and has built-in mounting points. 

With its unique strap the Race Pro looks like a radical departure from the norm, 

when in fact, the Race Pro mounts the same way as nearly every slip-on muffler from Cobra. 

The strap clamps tightly around the muffler and bolts to the bike's hanger mounts located beneath the saddlebags. 

PEM® fasteners in the wrap make mounting a simple task of threading in 

a bolt from the upper bracket into the Cobra strap.

The mufflers come with 3-inch cores encased in proprietary Cobra sound tuning materials with specific 

acoustical dampening and thermal insulation properties. 

The basso profondo notes are made possible because of class-leading resonance absorption and prevention.

The frequency and location of the perforation patterns in the high-flo cores creates significant sound scattering

 in the mid frequencies, which helps to enhance the low frequency tones. 

The high-flo core itself is a massive 3-inches in diameter which gives the muffler an aggressive look without the objectionable sound levels.

Like all Cobra exhausts the Race Pro slip-on mufflers are made in the U.S. 

and come with a limited lifetime warranty that even covers discoloration. 

They use precision laser cut mounting brackets and stainless steel clamps 

to mount to the stock headpipes or to Cobra's PowrPort Dual headpipes.
