Back to it, still dragging on this but managed to get the downpipe welded up and sorted today. Never welded really before this and certainly not stainless so I thought fuck it, throw on some stainless mig wire and give it a go. It’s not laying dimes tig quality but for something that’s gonna be out of sight and heat wrapped, who cares??
So I got a reel of stainless wire off eBay and with some research it seems it works fine with co2 just not ‘as good’ as Trimix. Well, fuck it.
Stuck the trusty Clarke into settings for 2mm steel and spent two days mocking up whilst the car was on a jack stand (how does Arran Kaufman do it?) and managed to get my angles right and good clearance under the subframe. The top of the downpipe was originally off a polo conversion but was just to short.

So welded up it looked alright. Just alright, not so bad it looked like birdshit but not that good I wanted to not grind it down. And the finished product isn’t that bad. I’ve even took closeups!
So next is to fit the lambda and heat wrap it, then mate it up to the original system for now. The downpipe is 2.5” so I’d like to make it all the way through but I’m gonna have to fit a cat off something else to pass emissions.
