I want to replace the original TR5T exhaust pipes and silencers with the High level exhaust pipes and silencers like the picture below;



Does anybody know what kind of exhaust pipes and silencers are used on TR5T in the picture?

It seems that the high lever exhaust assembly like the picture is for T100C models but I'm not sure which year of T100C exhaust assembly is better to use on TR5T. I mean, I think there are two types of high level exhaust pipes for T100C. Early type from 1967? to 1968(70-7020 and 70-7022) and late type 1969 to 1971(71-0017 and 71-0019). What are the differences between those two types? Do they both fit TR5T?
Also, are there any differences between early silencers and late silencers?

Is it possible to use the stay, bracket, clip and so on for T100C exhaust when using the T100C exhaust assembly to TR5T?
Are any modification needed?

Can anybody please give me advice on how to install the T100C high level exhaust assembly on TR5T? Any information would be appreciated! help

Thanks!

Great 1970s photo.
Let me guess--London UK?
BSA twin behind the TR5T? And Morris/Austin 1100/1300 car in the background?
Now to your questions. Afraid that I can't answer them all but here goes---
a) The exhausts on the TR5t in the photo look like T100C pipes to me.
b) The differences between the earlier and later T100C pipes are that with the earlier pipes the two pipes merged into one about level with the cylinder barrel and then one pipe went into one muffler and then to the rear. The later T100C pipes were as in the photo---two separate pipes from head to the rear of the two mufflers.
c) Do both fit the TR5T? Well-they will do at the cylinder head end because the TR5T and T100C used basically the same 500cc twin engine. However the T100C and TR5T used completely different frames. The T100C frame is a "dry" frame with a separate oil tank. The TR5T frame is "OIF"--oil in frame. So if the T100C pipes fit the TR5T frame at the back then you will be very lucky. To be honest--I don't know.
d) Unless someone has fitted the T100C pipes to the TR5T and can tell you what is what with it then I think if you are intent on this course of action you need to get the pipes, fit them at the cylinder head end and with the rear of the pipes/mufflers supported in the position you like, then you have to measure up and make brackets to suit.

The gleeming Triumph with the sad oily BSA C15 rat bike behind, the road outside my house resembled that in 77 wink .

And this may be the earlier T100C setup

If you have a "74 head the T100C pipes will not fit , off the shelf anyway ...

The pipes are going to be a real pain. First of all, the TR5T head uses slip in pipes - I'm not aware of anyone who makes or has made slip in high pipes as all the other 500's from before 73 or so use slip over pipes. Even if you could find a set of slip in high pipes or thread spigots into the TR5T head, they would not fit due to the BSA OIF. Even the down pipes from 74 T100R which are slip in's won't fit due to the frame. ..

Tridentman,

Thanks for your advise.
I just found the picture on internet so I don't know where it is..but your guess is inspiring! laugh

I didn't know the earlier pipes are 2 into one style. I like the later pipes though. I think I should buy them and try them but those high pipes are kind of expensive so I've been hesitating to try...

Thanks for the picture. Looks like The right side pipe is very close to the frame.

Does the frame interfere with the exhaust pipe?? confused

quinten,

Thanks for the link! I couldn't find that post. Interesting post. I'm aware that the 74 head is push in style. I was going to make spigots and fit the clamp on high pipes but according to the quote, high pipes don't fit??? I've seen many pictures of TR5T with high pipes which look like T100C high pipes but how did they do that? confused

Yes it looks like its touching the frame, you won't know until you try sadly.

I too have seen high pipes fitted to a TR5T ...these guys just say its not nearly
As simple as it would first appear .
The TR5T is built on the B50, B44 , B25 frame (all one cylinder)
so it could be clearance behind the downtube or how the
500 twin is centered/off centered in the frame , to make the drive chain line up ,
that make fitting T100c pipes more than a weekend bolt-up project
.

Kommando,

I should try but it's kind of risky attempt because those pipes and mufflers are not cheap...

quinten,

Thanks much for the info and link! I have seen the TR5T before in the picture. I didn't think the high pipes of his TR5T was stock T100C pipes because It doesn't look like the pipes are fitted over to the spigots. I'm surprised! I'm not sure how he modified them but it seems that T100C high pipes can be fitted to TR5T with modification smile

Hello machico. I got your PM but decided to answer in the thread in case someone else wants high pipes on their oil in frame. It has been some time since the TR5T build and the bike is long gone but I recall I used aftermarket T100c pipes; the silencers were a universal fit eBay score... I have no idea who manufactured them. The "outer" pipe was nearly a direct bolt on... I needed only to cut it to length and massage the return bend under the heat shield a bit to route it so my leg stayed unburnt. The "inner" pipe was trial fit repeatedly, and bent using both a bench vise (cold) and heated with a torch to make the small radius bends near the front frame tube. All fitting was done freehand, a bit at a time and test fit after each bend. It took several nights and I ended up still having to dimple the "inner" pipe a bit on final assembly as it just kissed the frame when the heat wrap was applied. If you want to run chrome pipes I suggest you start with brand new reproduction plain pipes and have them chromed after you are certain they fit as you desire. That system was a considerable amount of work but I ended up with a really unique look, and it sounded fabulous as well. I hope your pipes come out perfect.

Hello trumpetloon,

Thank you so much for your reply and your story of experience!
That's very informative! smile That solves the mystery. Your TR5T is one of my references and I'd kept thinking how he did that since I found your TR5T.Very nice bike!

I have some questions. Is the cylinder head of your TR5T "push in" exhaust pipe style? If so, how did you fit the T100C pipes to the head? Did you fit the spigots to the head like earlier T100C cylinder head?

Hello dommie90,
Thank you so much for your response.
I didn't know TR5T was produced in 1972.The frame is same as '74, right? What year of T100C pipes did you fit? Did you use reproduction pipes? Can I see the pictures of your TR5T fitted T100C pipes?

dommie90, I forgot to ask but do you remember how the head had spigots fitted? Is the head pre '72 spigotted head or did somebody fit the spigots to the push in style head?

I recall finding a set of retrofit spigots somewhere. I am sorry but I no longer remember where I got them.

PS i recall seeing another tr5t who tried to fit the same type of pipes and he had to belt the right hand pipe to clear the downtube it looked bloody ugly he told me that he thought the pipes were off a 650 triumph

It seems that the point is how well the right side pipe can be fitted to TR5T to clear the down tube. It might depend on how well the repro pipes are made but the minor error of the pipe bending might influence the fitting in positive way? Also I think the bending of 69 to 72 T100C right side pipe looks different from 67 to 68 T100C pipe so those differences might influence the fitting too.

Anyway, I decided to try T100C pipes and will see what happens.
Thank you guys for helping me smile

Were you successful in fitting T100 high pipes to your TR5T?

BSA Boy,

Yes but it was very hard to fit T100C high pipes to TR5T.
I had to cut and weld the right side pipe not to touch the down tube of the frame. Also I had to bend the left side pipe outward because the pipes were too close to the frame and rear shock. It was kind of difficult to make mountings for them too. The pipes and T100C silencers are still close to cylinder barrel, down tube of frame and left side cover but everything looks good and works good. It is kind of hard to remove them though. tired

I don't recommend to fit T100C pipes to TR5T. If you have good skills to weld and bend the pipes, it might be easy to do but Perhaps you should make the pipes. I won't do this ever again.
