Stainless Steel on Exhaust pipes and Peashooter silencers

Re: Stainless Steel on Exhaust pipes and Peashooter silencer

Reopening this old thread. Does anyone make quality pipes made of stainless steel now? I would lik to have a set 1 1/2" for my Roadster 750 short stroke.

38 years in the metal trades, Stainless looks far different from chrome plating.... stands out like a sore thumb. And.... these restored bikes are not likely to be left out rotting behind the shed, so, no advantage to SS. The silvery/pewter hue of SS is markedly different from bright chrome. JMWO :mrgreen:

Is not disagree with you, but these are test pipes and I will weld in sockets for lambda sensors in both pipes.

Re: Stainless Steel on Exhaust pipes and Peashooter silencer

My 2 into 1 exhaust is made out of mild steel and painted with temperature resistant paint. Rust is always a problem. Some time ago I was lurking around Moorabbin Airport in Melbourne and found a guy who is making aircraft exhausts out of Hastelloy, which is a nickel alloy and very light in the sections he uses. You guys in the US might have a lot more opportunity to explore this avenue. Might not be cheap, however a friend has a pipe made out of that alloy on his 350cc Manx. The colour is different from chrome - more whitish than slight yellow.

I've been getting some stainless mufflers and pipes from a stainless guy that lightly flash chromes them.
Adds a bit to the cost, naturally enough.
Best of both worlds....

Also got a few just stainless pipes.
If you keep them polished they look a bit yellowish,but still better than rusting,
or the chrome peeling off them at some stage (very damp/humid here sometimes).
The mounting points need to be made very strong though, or they might fracture around there.

I failed to read all posts, and the resurrection. Sorry for that. I was responding to ancient OP.
As for adding weld in bungs, no worries. Drill, buff chrome off 1/4" around your fitting, TIG weld, touch up the small heat affected zone with high temp silver. Done many repairs this way, works fine, looks good enough as well.

It is very difficult to successfully plate chrome onto chrome or onto high chrome steel alloys. It can be done, however it is likely to 'double coat' and peel off.

OK, but who is this guy? Is it possible to order pipes from him? Do you have contact info for him?

Re: Stainless Steel on Exhaust pipes and Peashooter silencer

I didn't buy Commando items, they were something else.
There were a few problems with fit, which is not so big a problem if they are close by.

So I'd be reluctant to recommend them for Commando pipes.....

You won't get the contract then to do this.

I've had a set of such pipes for 10+ years.
Not on a Commando though...
