Very disappointing fit and function. The "resonator" section has no sound insulation, just see louvres that constrict the flow down to about 1.25" diameter. The rear muffler is a chamber type, which does quiet the exhaust but also restricts flow. Additionally, the rear muffler case hits the heat shield over the gas tank, and the exhaust tip is angled out of the rear muffler so that it hits the rear valence.

Some of the reviewers above may have been rewarded for their positive & negative reviews. We don't hold anything back.
