Slip on exhausts

Nice quick service and delivery was prompt. The left slip on took a lot of persuasion to line up but once on very happy with look and love the sound they give. Had to get a stop bracket as I have a centre stand but had no instructions what so ever, so had to guess my way to fitting it. Over all love the product.

More bass sound than stock!

Gave my street twin a bit more bass sound than the stock muffler. Quite a bit of a challenge to fit with center stand. I don't know if I did it right... It changed the look of the bike, I think I'll keep it for now.

Great quality, quick delivery, good price

Loving the look and sound of the these shortys, they haven’t disappointed! Easy to fit (so the man tells me😏) . The only issue was that I have a centre stand fitted and it would have knocked on the bottom of the can- small piece of old exhaust bracket rubber fitted on the stand has sorted that. 2017 model
