Other than some muddled instructions (which, at least in the early version, showed the pipes mounted upside down) I am very happy indeed with these. They look more classic, and have a bit more of the traditional Triumph brap to them. Not super loud, but a bit louder, and overall a better sound I think.
After much research and watching/reading reviews I decided to purchase the Sleeper Pros. They shipped amazingly fast and the packaging was great. After fitting I cranked the T120 up and immediately smiled. A deeper more guttural note emitted at idle. Upon riding the difference really kicked in. Fantastic note especially when you hit 3000 revs and above - it turns the Bonny into a snarling beast. I am SO happy I bought these. Thank you
I have done quite a few mods to my 2015 Bonneville T100, but by far and away the single best thing I've done was to add the Sleeper Pros. Their tone is sublime! Added a few more HP to boot. What's not to like??
