1. After 300 miles
So I bought this because it wasn't much more than a slip on exhaust and I really liked the look of it. This is not an exhaust you should use on the street it is just way too loud... Must use ear plugs. Your bike will definitely need a PCV or reflash if you don't want to lose power. The build quality is also not as good as I had hoped. The overall fitment just seemed a bit off. The muffler ends up way too close to the rear tire and swing arm. This could be fixed by tweaking the muffler bracket but just not something I think I should have to do. I will hopefully be selling this used and picking up a different brand for my fz09
