hi all i have just bought a japspeed stainless centre pipe but its about 3-4" to long ? so after having car up and having a walk underneath the easiest way to make fit is to cut a piece out and re-weld it ? so that way all the mounts line up still . only a friend told me stainless still cannot be welded ? is this true ?

cheers all

Dave

 

Not true. It can be welded.

 

I always thought stainless was a doddle to weld........it's how they make them

Shaun

 

ok very good news that ! cheers

 

think he means it cant be welded with your normal ( mild steel ) welding gear

which in fact u can lol it just rusts where you weld it if u dont use stainless steel mig wire

piece off **** tbh

 

how else is the system mated together if not welded ?

 

yeah i know its welded i can see the welds on the pipe basically just finding out how to weld it ? so it needs to be stainless steel weld ? is this equipment standard at most garages ? i dont want mild steel to be used if it rusts ?

 

stainless steel is easy to weld, but id use a tig welder to do it. you will have a lot less chance of going through the pipe and it looks a lot neater, usually exhaust pipes are 304l Stainless Steel so you will need 308L stainless wire

 

I'm going back to my school days but don't you have to weld stainless under Argon with SS wire?

Shaun

 

yeah you use argon with t.i.g and argoshield with m.i.g also if its a butt weld you will need a backing Gas but if there just putting the flange back on you wont need a backing gas and 308L wire is SS

 

sounds like you bought a hawkeye exhaust mate...

 

nope,try a longlife or powerflow centre or failing that an engineering firm.
