Installation Process

The Sleeper Pro Slip On Exhaust installs in under an hour with common tools. Simply remove the factory exhaust and bolt on the Sleeper Pro. Remapping is not required due to Triumphs "self-learning" ECU that can adapt to changes in the exhaust. When installing alongside our Competition Header it is highly recommended you seek professional help to re-tune the motorcycle.

Estimated Install Time - 30-60 minutes

Not Available for Sale in State of California

Each state has its own emissions and inspection requirements.  In California, this is managed by the Air Resources Board (CARB for short).  CARB has determined that certain aftermarket motorcycle parts are not legal for sale or highway use in the state of California. Items subject to this determination include certain exhausts, fuel controllers, and other parts that might affect a vehicle's emissions.

British Customs has determined to the best of its ability which items are CARB approved and which items are not - items that are not CARB approved are not able to be shipped to addresses in California or used for on-road use in California. 

Items that are not CARB approved may still be utilized in the state of California, provided that they are not used on a public road (i.e. only used on a closed course or offroad).  At this time, British Customs cannot verify if a product is used for closed circuit or off-road use and cannot ship to addresses in California.  

For more information, please refer to the CARB's information page.

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've lived with the Sleeper Pros for some three years now. Combined with the other modifications I've made to my 2010 T100, they transform the bike. Unlike others I tried, they fit. But nothing is perfect. They are significantly louder than the stock Triumph pipes I had (TORS). As I get older, I'm starting to appreciate quiet. So yesterday I returned to the stock sound. That's not a knock on the Sleeper Pros. They're great. It's a personal thing.

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??

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.
