Thank you for your compliments Mr. Mike! That means a lot to me coming from a grizzled sidecar veteran like yourself.
Dauntless / DMC is local for me too, so it's nice to be able to stop by and say hello. I had them inspect mine after purchase and we found a worn swing arm bushing. Had it replaced, added windshield and soft door too. Was charged one hour labor plus parts. What a deal!
From a previous post 5-6-17;
Bought a used stock Triumph Thruxton exhaust system for my Scrambler.
As I understand it, the right silencer will need to be relieved a bit with my hydraulic press to fit under Scrambler rear master cylinder.
I believe the left silencer will fit fine, as well as the pipe which is said to be 2" longer than Bonnie pipe with a steeper angle to the bend up at end of pipe. Silencers are shorter than Bonnie silencers.
This will replace the high exhaust I now have to reduce leg heat, prevent rain pants melting, and get pipe out from under my leg for improved counter balance during sidecar cornering. I'll know more when I get into the job and see for myself. I almost got it for free so I can't lose. It's a bit of an experiment, but I think it will work and that I will like it.
Any thoughts on how this might affect the map? I am removing (and saving for later) an Arrow 2 into 1 system which came with the Scrambler so I'm sure the map is presently set up for that.

Good News, all concerns of internet nay-sayers have been dispelled! At least the ones who think it’s hard to switch Thruxton exhaust onto a Scrambler. After removing Arrow 2-into-1 high exhaust pipe and silencer from bike, which came off easily (once I employed my ¼” drive, 12mm swivel socket and 6” extension for exhaust flange removal). The Arrow is a nice quality piece, and from that perspective I had some reservations, but I just don’t want high exhaust, and I love the low dual pipes.
The only things I had to do to fit the Thruxton pipes is remove the two large allen head fasteners that hold the master cylinder mounting bracket to the frame and swing it out enough to provide clearance for the pipe to come in behind or inboard of it, along with the lower rear DMC sidecar mounting bracket, which also went right back on as soon as the pipe was in place.
On the left, it looked like my kickstand, which is unique to the scrambler, might get in the way and since it was no longer needed for sidecar tug duty I removed it. It will be kept with all other original parts of the scrambler which were passed on to me, for posterity.
I was astounded at how perfectly the right side pipe fit in behind the master cylinder. Triumph really engineered that one well, even though Scramblers always come with the high pipe. Right along with that are the excellently engineered DMC sidecar mounting brackets which, just as Jay the owner of DMC assured me it would, fit perfectly beneath the pipe.
During my research I saw a set of stock Thruxton pipes for sale on eBay and according to that listing (contrary to internet rumors) the Bonneville, and Thruxton pipes are the same with identical part number. Obviously, the silencers are of a different design than the Bonnie, and have a steeper upward angle, but it does appear that everything interchanges.
One complication for those with Fuel Injection who want to retain their o2 sensors… the Scrambler sensors are basically under your right knee (when riding) with the Bonnie - Thruxton bungs being down by your toes. This required me to cut and splice in new wire using crimp connectors and shrink tubing. Be sure to put tubing over harness before crimping, ask me how I know!
I believe also, that the wiring harness under the gas tank (two rear seat bolts must be removed, two rear tank bolts removed, tank lifts up) is different, Scrambler has one harness connector coming right out of a large diameter wrapped main harness, and one comes out with about a 10 inch long sub-harness of 4 wires. This required me to make one 02 harness about 10 inches longer than the other.
I did have to purchase the mounting hardware from Triumph including special bolts and grommets as well as two silencer clamps which were made of stainless steel and galled the threads upon installation. Long story short on that, I got two aftermarket ones ($8.00 for the pair) which were stainless clamps with plain steel bolts for tightening (anti-sieze was added to threads just to be sure).
Here's a link to my clamp adventure;
https://forum.classicmotorworks.com/index.php/topic,12246.810.html I love the way my new Thruxton exhaust looks on my Scrambler Rig! Something about it reminds me of the Nortons my older brother had when I was young. I think they really look cool and proper for a British bike.
Oh, I almost forgot to mention, the used exhaust system was purchased from some nice people off craigslist for $100.00 Thank's Starla and Rob for the great deal!
