Now I am getting close to having completed the rear sets on the A65, it is completely clear (although I did guess before) that I can not run a standard exhaust setup as the rear set brake pedal won't come near the silencer!
So I am faced with a Choice - but it means new exhaust system (and more money DOH!)
I could fit the clubmans type Siamese with the clubmans silencer - a nice looking setup, and if I avoid armours, then I should get some nice bends on the pipes
Or fit a set of TT pipes, I can add some kick outs and have silencers poking outwards (as its a road bike, I don't think id be popular running open pipes)
or try and some silencers that will work with the setup.
I have found in the past that lengthening the pipes seems to bring the torque peak down and doesn't rev out as well as a short pipe setup.
Allan, I have had excellent results with the Siamese just as you describe it. Much better torque/power almost everywhere with a minor sacrifice at the top. The TT pipes will be weaker in all useable rpm areas. Those are the dyno and seat of the pants facts. PRT
Allan...I just installed Siamese pipes on my bike because of interference with the left silencer and rear sets. I found a used set on eBay for a good price. Was very happy with what showed up at my door...never know what your going to end up with a used eBay item.
Don't know if they are old BSA factory made or not, thick wall pipe and old heavy chrome that was in pretty good shape.
I can tell you that I saw quite a bit of mid range performance pick up...it just goes through the RPM'S a lot faster.
Wasn't sure if I wanted to give up the sound and look of twin Brit pipes. To tell the truth I really like the new sound, still sounds like a Brit twin just a bit more mellow.
There was no crossover tie with them so I came up with this.
I used one of my old megs with a kick up so it came just under the footrest.
I even like the look, left side has more of a race bike look to it. So I say go with the Siamese pipes.
Roger, I see you have kept with the megaphone. I was thinking of sticking with one of my straight through Brituro muffler or using the proper LC style muffler.
Do you have a link from the eBay pipes? I've seen some which fit the frame nicely like the originals and the armours ones I bought once had a real ugly wide bend on the LHS pipe. Stuck out a long way! That's how I ended up fitting twin pipes.
Allan, can't reply on the siamese system, but what I found with new Brituro A65 silencers is that the fit, sound and performance is good, but after just approx. 1000 miles one of them disintegrated on the road, I lost the complete welded-on rear part with all baffles. The other side started to rattle inside as the baffle came loose. Not what I expected. What was amazing though was the increase in power and rpm's. I run pipes without balancer but with only one empty silencer with the lost end portion the bike ran like wild. I was really impressed! It was very loud though.

I have contacted one of the suppliers on ebay (Classic bike shop) They tell me these pipes (in the link) are T.J Wassel pipes and look about identical to quite a few that I have seen for sale including Brit Cycle
Has anyone used these particular pipes? can you post a photo of your bike with them on? and I would be grateful to hear your views on them: the fit, chrome, how well they keep their appearance.
Later Firebird style are good, they have a balance pipe down near the mufflers. I've experimented with bigger dia versions with a good X connector and two mufflers that gave very good top end. Maybe some closer to std dia with X connector could be nice and look good esp if made in stainless. Also earlier style high pipes one down each side can be nice, but may loose a little compared to ones with X connector which the both up the same side lend themselves to.
Rich, Fabulous looking bike! My own Hornet looked about like your bike when I was street riding it. Siamese, Goldie, Big Spitfire tank, mandarin. I have a bit of a connection to SLO. My mom grew up there where granddad was a fixture at Cal Poly for many years. He is known as the father of Poly Royal. Wish I could live in 2 places. PRT
