FMF Powercore 4 Slip-On Exhaust - 4-Stroke

B Eazy426 - Upstate New York
4 out of 5 stars
Looks awesome on bike. What you get is not picture "I bought this thinking I was getting exactly what was in the picture on the website, it is pretty close but not exact, the most disappointing part was instead of a welded tab on the top of the canister they sent me a metal strap bracket with rubber lining, when you pay almost 400 dollars for an exhaust and it says exact fit in the description and in the picture it's a welded tab that is what you expect, also there was a small but noticeable dent in the aluminum canister, but overall it is still very nice looking compared to my stock exhaust, I paired it with the FMF Powerbomb header."
