Title: Exhaust maker
Post by: Clive on May 18, 2015, 07:35:02 PM
Is there anyone on the forum who could make me up a simple pair of exhaust pipes?

Would like a matching pair, very similar to these examples.

Please :)

They're both standard bike downpipes Clive, (the original bike's pipes minus the silencers). Loony fitted slash cut ends on his.
I've got a Clarkes hydraulic bender at Loony's workshop you're welcome to borrow, but it's meant for heavy walled tube & would probably crush thin walled exhaust tubing. Packing the tube with dry sand's supposed to prevent that, though I've never had much luck with it. It's there if you want to have a go.
Or you can buy pre-formed bends from somewhere like Custom Chrome. That's what my Pop exhaust's made from. About a tenner a bend in stainless.

Cheers buddy. If I end up buying bends, it'll have to be non-stainless as it's all I have the ability to weld.

I'd like to have them made out of a single piece of stainless, but I'm sure they're quite small diameter (not measured them yet properly), and that makes them harder to bend, right??

Probably. Custom Chrome, (the exhaust people, not the aftermarket motorcycle parts company), sell mild or stainless tubing in all sorts of sizes, as do lots of other suppliers. The Pop exhaust headers are made from a series of bends & straight sections butt welded together & smoothed off. Cost £300 ish to make the 8 pipes. Welded with my MIG welder fitted with a small reel of stainless wire & using the same Argonshield gas I use for mild steel. I've got a spare reel of stainless wire if you need it, (not cheap to buy).
Your bike pipes will probably have a flange at the engine end that you'll have to make -basically just a flat washer that the exhaust collar pushes against. Not too tricky & you can get creative with cross over, curly wurly pipes, (my XS ones cross over & wrap around the frame tubes).

Clive you won't bend stainless,
It's a job for the professionals,You will need to use pre-bent tube.
One other thing to get these pipes to fit properly the pipe maker would need the bike,
So that counts me out as I'm to far away,But Andy's offer sounds good.

Nope, I didn't, but am now looking for a set to be made up for the latest build.

I followed my brother's suggestion & used Torque Technique in Wilton, near Salisbury, Wiltshire for my bike pipes. I originally made my own from pre-formed mild steel bends, but they fractured because I'd sanded the welds down flush. So I had them re-made in stainless.
Nice job, very friendly service & done in 2 days. Cost 220 quid though for 2 full length pipes, (they run down the left side of the bike as far as the rear wheel spindle). Not cheap but no more than any other specialist exhaust manufacturer.

Cheers Andy, that's my plan also, or the lad whose details I'd sent you a while a go.
