Hello TurboboyHi
Looking for some good quality 1.5 inch unbalanced pipes for MK3 , nice hugging set
Can anyone surgest a supplier.
Cheers
Otherwise, Colorado norton works do sells stainless ones . Matt Rambow is the contact 1 3/8 for sure 1 1/2 check with him.Hi

Indeed. That’s what my dyno testing showed.Your bike will most likely be a little quicker machine with 1-3/8" on there vs 1 1/2".

I had a set of 1 1/2 " pipes on an otherwise standard 850 about 35 years ago. They did nothing for performance.Indeed. That’s what my dyno testing showed.
When I first built my 750 I had a 2 into 1 exhaust (1 1/2" )with a short open meggaWell, when I fitted mine and road tested them I was convinced they gave a performance boost.
Sadly it was a classic case of unreliable arse-dyno-itus !
The dyno showed a big hole in the mid range. Which made it feel strong when coming out of the hole. Even peak BHP was lower as well.
Different engine tunes may get different results though of course.
The sound from the Viking's 1 5/8 was the most exciting I've ever heard from a Norton. The roar on acceleration and the sniffing on compression were a real addiction for me. I agree that I never observed any performance increase indeed. They looked so good but were so unreliable for the price (2000$). I've always hated the look of the small dia. 70's british bikes. The 60's looked a lot better.Well, when I fitted mine and road tested them I was convinced they gave a performance boost.

Bigger looks and sounds better.I can't argue with the small pipe = better power especially if a dyno supplies the facts. But I much prefer the looks of the larger diameter pipes. My Atlas has stock 1 5/8 pipes and the original mufflers and runs REALLY WELL. The only modifications are a Boyer and a single Mikuni.
While I'm here I need another set of 1 5/8 Atlas pipes for a project. All I need is usable pipes, do not have to be gorgeous.
This is off topic, but I made a 2 into 1 exhaust work on the road on a 750 Norton. It took a while for sure. I had to lengthen it and make the motor breath considerably better. It really likes the 35mm FCR's, and was happy with the 34mm Mikuni's previously. It did not like the 30mm Amals, and neither did I. It's not all roses though. It doesn't sound like a Norton with dual peashooters on it. As configured, it has lost that nice round Norton exhaust note. I miss that sound, but it runs great.When I first built my 750 I had a 2 into 1 exhaust (1 1/2" )with a short open megga
It sounded glorious but on the road it was a disaster, despite all of my best efforts with jetting and timing it just didn't work,or I should say I'm not clever enough to make it work!!
I fitted non balanced downpipes and pea shooters and with no other changes normal service was resumed
