If you get the obx v-band they have a lip for sealing check this out

(The v band for the turbo should be flat and fit plush with no gasket needed so if it fits perfectly on the turbo then good) but for the rest of the exhaust you want the obx v-band with the lip..

Its no problem if the welder your using can weld stainless steel....for example I have a mig welder that says "not suitable for stainless steel" and I another mig welder that welds stainless steel and will weld stainless and mild steel together easily. I have a tig welder that will weld stainless steel and mild steel together easily. So it depends on the welder but as long as it can weld stainless steel its easy

Also, for future reference Tony - yes mild steel and stainless can be welded together no problem. My muffler is stainless welded straight to my mild steel.
Of course, you have none of the rust-proof benefits of the welds when you do this via MIG welding with normal C25 gas or whatever. But that's somewhat irrelevant anyway if the rest of the system isn't stainless.

less of an issue with it's out in the exhaust tube...more of an issue when it's feeding the turbo....but that's personal preference.

a MIG welder should be able to handle mild steel or stainless steel as long as you have the proper wire loaded up into it...and if you have the correct gas.
why would one MIG have listed down not suitable for SS? it a flux core welder?

Yes flux core

But given the vast amount of mild steal options for the collector he shouldn't even be trying to bother with it regardless
I was thinking the same thing. I've never seen MIG stuff listed as "not suitable for SS", and figured it's all just subject to wire and gas requirements. Then again I've only ever messed with my Hobart MIG so I figured maybe this "not suitable for SS" bit is maybe an issue with some other MIG welders

Good point. My SS bit is at the very very back (muffler). My flex section is probably SS though. But then again can't really get away from that there.

I was talking about a flux core welder which is a gasless mig (uses self shielding gas within the wire itself) it's not suitable for stainless steel. I call it a mig because well it looks just like a mig. Here's what I have

But yes now I understand what you mean. Years and years ago when I had a crappy $100 flux core welder I tried to weld an SS tip to an exhaust and the SS stuff was just totally immune to it. I was like wtf is this black magic

Yes I know what flux core is and how it works but flux core is not MIG. The very term MIG itself implies the use of gas. So it never even occurred to me to think of flux core stuff when we're talking about MIG welding

Welding stainless to mild steel need to use 309l wire/filler. Stainless to stainless 308 wire for 304l and 316 for 316 with a tri mix gas. Same with tig except straight argon.

so basically you leave the same set up as mild steel. you CAN do it...but at that point might as well run all mild steel piping.

honestly...unless he's willing to ready to get serious with this and start welding other stuff then what you're recommending him to do is a waste of time and money.
he would need to get a mig welder, the gas+tank, regulator (if it doesn't comes with it), helmet, gloves, protective gear, wire...other BS (nozzle dip, grinder, fiberglass mat, etc etc) before a MIG gun can hit any metal. that's quite the investment for an one time set up.
let's not go into the time to learn how to weld....the materials he'll waste on welding scrap tubing. then if it's a turbo set up he'll need to get a chop saw...even an HF one is still some cash.
anyone can glob some metal on a pipe and have it stick..but someone that actually puts in the time and effort to do it well is a true crafts man.

and anything Stainless he can get welded and he'll have the satisfaction from doing it himself

you think he'll take the time to learn how to weld himself? a leak free weld? really?
go back and read my last line.

The person asked about welding because I believe that he/or she wanted to attempt to weld themselves this would be a perfect opportunity to start. For all we know he or she could be a natural at welding and be very good at it and the money shouldn't be an issue because (lets just call this person a he) he is going to have to come out of pocket regardless because he's trying to turbocharger his car ( never ending money pit) im sure most people heard the saying " if you want to play you have to pay" now im not trying to be a smart guy in any way so dont take anything im saying the wrong way but he asked would it be hard to weld stainless steel and mild steel together and the answer is no it isn't. Ever since i answered his question i feel like im being targeted here when im just trying to help and boost his confidence. I thought this was a fourm where we help one another and share our ideas

if you welded in the past and know what you doing and have the right equipment...sure it's a lot easier.
the forum is to give sound advice to people.
if tony want to buy the equipment and start welding then he should go for it...but he will need to make a significant investment (time and money) to it in order to make good/leak proof/structurally sound weld.
