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

After a few hundred miles, I transformed the bike a bit and the 1st main change was an addition of the Sleeper Pros and the Xpipe from BC. The bike WOKE UP! MAJOR seat of the pants transformation and the entire rev range became usable. No more bogging at the 2k to 2400 rpm range. The bike feels and performs 100% better. It also sounds and looks AWESOME. Best money spent in a very long time!

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.

I purchased the chrome polished sleeper pros for my Black T120 they literally took me 10minutes to change them over. I am more than pleased with the look and boy they sound good and the bikes performance feels better ,make sure you purchase new gaskets too you have to buy them separately.
[Note from BC: Due to this customer's review, we have updated the Sleeeper Pro to include factory Triumph exhaust gaskets.]
