    Perfect sound and weight reduction

    I was sick of my bike sounding like a high powered sewing machine at idle or a high powered lawn mower while riding. Yoshi gave my bike that perfect deep WOMP noise perfect for riding on the freeway so you are heard before you are seen. Yoshi doesnt make their exhaust completely ear bleeding awful its literally that perfect blend of "im in you blindspot right now and I know you can hear me but im not a douchebag trying to destroy your ears or mine."

    Great Exhaust

    Great sounding exhaust, looks sick too. My only problem is that it makes doing oil changes a lot more annoying (headers wrap around the oil filter, so it's difficult to take out/put in a new one). Besides that, I love the exhaust
