Not content with the bark from his Vance & Hines silencers Dutch wanted to improve the soundtrack of his Triumph T120 'Hoxton', and hopefully release a few more ponies too.
There are a few de-cat options on the market for the latest water-cooled Triumph engine but on recommendation from Camera Dan he went for the Free Spirits X-pipe. What Dan didn't mention was that his T100 Bonneville and the Thruxton are slightly different, which caused a few headaches, grazed knuckles and swearing.
There are also plenty of other instructional how-to vids here on the YouTube but this is our have-a-go attempt at fitting. Being men, Dutch & Dan of course tried without the aid of an instruction manual.... but ended up downloading one from the Free Spirits website.
For the rest of us it was a pleasure to stand back and take the piss out of the guys and their struggles, leaning over their shoulders sucking our teeth and suggesting alternative methods.
Dutch is well chuffed with the extra decibels and crisper sound and we'll be filming a follow-up out on the road to see how the boost in performance feels.

To everyone asking about the ECU Remap, Triumph introduced the "self-learning" ECU in 2016, so no remap is required. Before that, you would need a remap if you are looking for performance. But if it's just noise you're after, no remap is required.
Rigbybigdog the T120 isn’t as trickier job as the thruxton as there is no balance pipe to mate up at the same time as the collars, header pipes and cat pipes. That’s the frustrating part. It’s way more straight forward on the Bonnies and should take 2-3 hrs if you take your time. Definitely worth it though and could save you a pretty penny in labour if you’re brave enough. [Dan]
As it happens, the warranty is not necessarily voided by doing this, unless any parts that are subsequently broken can be put down to being caused by this modification. It also depends how much of an asshole your dealer is. A good dealer will honour an unrelated warranty, as the relationship with a loyal Triumph customer is paramount.
Not sure if you noticed any of the bolts on the frame were not to spec?. One Sunday, when I was bored, I went through and checked them all on my bobber and found some not to spec. Not horrible just in need of tidying up a bit. Cheers.
Hi, I found some of the bolts not torqued down to the factory spec on the frame. Hence going through and checking them all. I would not have found this out except I was preparing to install the crash bars and was doing a dry run to ensure I had everything for a successful installation. I wanted to add the crash bars which require the removal of some of the same bolts. Btw great channel, Cheers.
Here's a question: If you wanted to put a whole system (new headers and cans) on that bike, could you simply bypass the CAT and leave it bolted in and hanging up there? Would there be enough space for the new pipes to pass right by it?
looks like you do need to shift the tank on the thruxton, but on a street twin you don't need to loosen the tank, or remove anything completely but the mufflers. I did it in under 4 hours. all about having the right tools on hand. and that was with the bike on the ground with only a paddock stand.
Just fitted the TEC X pipe to my Thruxton R.
Great piece of kit, slotted in perfectly........but as you illustrated, getting to it, what a bloody palaver!
Still watching your video meant forewarned was forearmed.
My next adventure, fitting the fairing. ..........should be fun!
The fairing will be much easier. Look out for those fiddly brackets under the tank edges... Plenty of chance to keep dropping screws. ... Also, if you're thinking about new front indies, maybe ditch the indicator bracket element, as it's fug ugly. I may hacksaw that bit off later.
It's also about reduced weight, added midrange, and no video audio can really capture the sound difference - also remember this bike started with the race end-cans. Bikes with standard pipes see and even bigger sound upgrade.
Looks like the challenge was well worth it. Does sound a lot more meaningful. I can imagine the cutting room floor being littered with Fbomb clips. Great job though. Looking fwd to hearing of the performance gains.
Really diggin this video series. Keep up the great work!
The bike would pass a normal MOT, but possibly not an SVA type approval (not that you'd ever need one unless you imported or exported the bike). The complex answer is that, no, it's not strictly "compliant" to do this, but everyone does this kind of thing in the UK. ...As soon as you start modifying any new bike you are stretching the rules of the homologation certificate against which the model has been certified in it's country of sale. An SVA test "might" expose this mod as breaking the rules. However, having been through an SVA I believe this bike would pass the drive-by noise test and be approved - as I have not seen any motorcycle test performed, model-by-model, that measures emissions - yet.
The scrambler does sound better than the Thruxton, but it has a two-into-one, super-short, straight-through, single-skin pipe with no baffles. The Thruxton has the race pipe with some baffling, but is still twin-skinned and the X-Pipe still routes gases through the "X" under the bike, and this probably mutes some sound, despite the lack of baffling.

I went to a trade school and got my welding certification and that was not enough. I found CDA technical Institute online and decided to become a Commercial Diver because of my love for the water. I had the best time going through CDA Technical Institute and I would definitely recommend this school to anyone looking for a career in Commercial Diving.
