Triumph Bonneville T120/BRITISH CUSTOMS Sleeper PRO Exhaust/Awaken the Beast!

At last i have the British Customs, Sleeper Pro exhaust Silencers fitted and tested! These pipes really do make a substantial difference to the performance of the bike!

Sir Stuart. I have discovered a new financial phenomenon that is sweeping the world of Bonneville owners. I have found that my bank balance is inversely proportional to the amount of time spent watching your reviews . That being said the smile on my dial is proportional to hours spent watching . I’m the luckiest man in the world as my wife loves watching your videos and even paid for the sleeper pro’s due to arrive next week.
You are my hero .

I fitted a set of these on my 2021 Speedmaster within the first week of owning it, I absolutely love the sound and performance. 3500 miles so far and I'm still in love.

Just put the Sleeper Pro silencers on my '18 Bonne T120. It still has the cat (until I get my x-pipe) but the new pipes still gave it a whole new sound. It's a little louder both at idle and on the throttle but it doesn't have that "talking through a mouthful of cotton" sound anymore. That, and the tone is throatier between 3k & 5k RPM. My only complaint is I can no longer get the side stand down with soft-soled shoes on because the peg is mostly under the pipe now. As for adjusting the chain, the improvement over the stock silencers is marginal when the bike is on the center stand, but it's a lot better with some weight on the suspension. In fact, adjusting is no problem now, especially with 12mm & 13mm angle-head wrenches.

Four years later, and these instructions still work. Just installed mine today. Thankfully BC now includes the graphite exhaust seal when the send the set. Didn’t even have to remove the passenger peg on the left side. And yeah…they sound much better, breathe better, and without the CAT, the whole beautiful T120 is an exciting experience.

Stuart, I have always enjoyed your reviews for the Triumph T120. I have had 39 motur-psykles, and looking at your video's, I may have fallen in love with the Triumph Bonneville! Just something of a classic bike that has some old school things, modern things, and what you brought to the table is - the British method of doing things...not always right, but make the bike what it is. Thanks for taking the time to make the video's, edit them, and publish them, we appreciate that very much!

[barntonman]

I have British Custom Sleepers on my T-100 too. You are clearly a man of refined taste.

[scothunter]

Mounted the Sleeper Pros on my T100 a week ago and am quite amazed. I had previously de-cated the bike which improved both sound and performance but the Sleeper's took it all to another level. Especially love the low rumbling tone. Great product!

[pritulaag]

I won't lie, at first watch, I thought the original silencers sounded better. But, after clicking back and forth a few times between sound bites, and listening to you talk about how you felt the old silencers sounded, I totally agree with you! I can't wait to start modding my T100 this year!

2017 T120, I watched many exhaust vids. For my bike before choosing the British customs sleeper pro. They were great to work with. I had my mechanic install a power Commander and decat system. The bike sounds better with this exhaust and is just a little bit louder. The performance that I have now makes this bike so much fun to ride! It’s tough to choose an exhaust from a video. If you want performance in a little bit more sound this will be perfect. I also have a triumph 800 XRX and I watched videos to choose a pipe and ended up with the two brothers slip on pipe. For me in real life the two brothers sounded great but it is just extremely loud and gives me a headache. Yes I do ride with earplugs. Great video thank you. .

[phillippayne]

just bought the t120 and these pipes are being fitted for when I pick it up but I bought the t120 black can't wait to get it...kind regards Phil

Hi Stuart I did a track day at castle coombe back in the summer, they did a noise test on my bike at 5000 rpm, 27 dB on Triumph standard exhaust system, was told the guy in the shed talks louder than my bike! Didn’t like corners as pegs are low.
Great video as always, looking forwards to next weeks. Dave G

Mr. Fillingham, I am seriously considering the T120 as a new bike and found your channel looking for information and reviews on various Triumph models. I have to say that your videos a better marketing material than we get from Triumph Corporate here in the U.S. Thanks for the great information and well done, sir.

[iivaridark]

It looks very good and as what I can tell sounds too. Well, most important is what kind of sound comes to the rider's ears naturally in a riding situation engine working at a load. Oh, and the beginning was Real Art!

[dennisbuckley]

Nice pipes, beautiful bike and another excellent, detailed step-by-step video with plenty of top tips 👍 Might be worth adding to have somewhere or something suitable on/in which to place the Triumph pipes immediately upon removal to avoid them getting scratched.

[Kitoj]

Hi Stuart. Awesome as always. I figured that gas consumption would improve. So 12 miles more per tank on the long run is an improvement indeed. I would love to see a follow up video in the future in regards of chain adjustment. Overall the bike looks great, sounds great, but still looks very classy.

[mikepat]

I have watched 10 to 15 of your videos and like them all. a real down to earth RIDER ; no nonsense great advice and tips to cleaning your bike and maintaining them. Oh and of course your evaluations of aftermarket parts I don’t currently own a Triumph or Royal Enfield but looking into buying both brands. Thank you for your videos.

[johanneuringer]

Hello Stuart, i very much appreciate your profound expertises in your vids. I also have the T120 Diamond and i am considering to build in a new exhaust. I saw your vids about the predator pro shorty and the sleeper pro. Which one of the two would you recommend (using with an x-pipe)? I asked my Triumph dealer and he would not recommend any of those two because they seem not to have european permit, instead he recommended the Remus exhaust. Do you have any permission problems of the PROs in the UK or is there anything you could recommend in this regards. 
Any advise is greatly appreciated
hope this is ok to ask and hope you read my comment

[Dave-in-France]

As always Stu, a high quality production on an interesting topic. Those pipes sound lovely.

[PHAASM]

Hi, thanks for this nice vid. Was wondering what brand are your bar end mirrors and if your satisfied? Looking for the exact same one for my t100 with a 1" handlebar.
Thanks

Hi Stuart
i was looking around for videos on exhaust systems and came across your clips. You are doing a fantastic job. Your videos are really nice with lot of information. Its superb.
I own a Bonne T100, 2015 model, liquid cooled, EFI. I am looking at changing the stock exhaust with an exhaust which sounds better and deeper than existing stock exhausts. Would really like your expert advice on this if possible. Thanks
