Cobra, 4" Race Pro slip-on mufflers

Chrome with gloss black muffler strap. Great flow & go. Internal technology is identical to the tried & proven PowrFlo and Tri-Flo mufflers. Comes with a 4" diameter body, expanding after the muffler strap, to 4 1/2". These slip-ons are an excellent choice for those that want that extra performance and a super deep sound from a traditional muffler. Destinctive styling elements, like the clamshell laser cut muffler strap, give it that little extra without becoming overkill. This one fits the traditional lines of the Harley-Davidson Touring motorcycle like a glove.
