I already work in a place like that!
Stainless holds the heat longer than mild steel, so the weld sinks in a lot more. Wasn't pretty, but a couple of hours of adding extra weld into the low spots & filing it back by hand did the trick -don't think anyone would employ me to do that, but when it's your own time, you can spend a whole evening messing about with one piece. The 8 stainless header pipes took weeks to clean up, but I'm glad I took the time to do them.
Got 2 weeks to get the Pop back on the road now for the Basingstoke transport show.

Yup, 150 MIG with 0.8 stainless wire.
Another day of rain here today, so back to the indoors job. Both pipes now cleaned up.

The 2 silencers bracketed together with a flat strap on either side, plus a pair of hanging brackets that bolt to the underside of the battery box, (stainless strap obviously). Got to clean these up as well now.

It was at this point that I realised I'd welded them the other way round to the old pipes. Doesn't actually matter, but shows I wasn't paying attention!
The new stainless set-up weighs less than the previous mild steel one, which surprised me.

Nice.
Mild steel ones tend to be made of heavier gauge material. Otherwise they don't last very long.

True. We drove the Pop for a month or 2 after they started salting the roads for the Winter & I'm amazed how quickly the corrosion set in. The mild steel system's only a year old. I'll replace the rest of the exhaust, bit by bit, over the Summer.

Trouble at mill.
The 4 mounting holes for the rubber exhaust bobbins needed slotting to fit. I started filing them by hand but soon gave up on that idea, so Loony fired up his Dad's milling machine to get the job done.

Shiny new pipes bolted in place. Now I need to hook the new silencers up to the existing system -or maybe I'll just leave them unconnected, just for show!
Exactly the same as the previous set-up, but much more noticeable now they're shiny instead of rusty black. They'll go a pale yellow colour once they get used a bit.

You can see here how tight the bend needs to be to connect to the existing pipework.

Mr Loon was primering a customer's car today, so blew a few coats over the Pop fuel tank too. A couple of small areas to fill & some more rubbing down to do, but doesn't look too bad.
