i know you can MIG stainless and all that good stuff. i dont know if my friends MIG welder has a back purge or not. i also know that out of respect for him and his stuff, i dont want to toy around with his welder( cause hey **** can happen! )


if i do go the stainless route! ill prefab everything up and take the parts up to Jason at Enthuza and have him weld it up.........

 

im just trying to source parts for my build. i have been searching and i havnt found anything in the way of pre bent 3" pipes..

but after reading a few peoples post i think i have pretty much figured it out and all i have to do now i wait to see if anything pops up on ebay!

 

That's a good option, tack it and have a shop finish it. If you call around to a few weld shops, you may find a guy who will do it on the side for cheap. Find a small "back alley" shop and drop by.

Welding is welding, don't need an exhaust shop to do it. I get a local guy to do my aluminum welding (my TIG doesn't do aluminum), I buy him a coffee and give him $20 each time.

Also, remember that stainless is going to change shape a bit as it's welded (it pulls more than mild steel) so it's best to do it in pieces, don't tack them all together and finish weld at the same time, do all except the midpipe, then custom fit that and finish weld.

Good luck.

 

I wouldn't buy raw material on ebay if I could avoid it. You may end up w/ very low grade stainless.

 

thanks for your advice fluke. its much appreciated!

thats pretty much how i planned to build the exhaust! ill be starting with a bolt in metal core cat! then the mid pip will be mocked up and as far as the axle back i wanted to do a slip joint and use a v-band!

 

Why would you use a slip joint and a V-band at the same time?! Arent bolt in cats more expensive than unflanged ones?! I'm planning out my exhaust build too! But I think i'm going to go mild steel instead of stainless! Cause its cheaper!

 

im doing a bolt in so i can take it out after emissions and put in a test pipe!

my bad on the v-band clap.....ill be using a lap joint clamp.

 

I used v-band clamps before and after the cat for this reason, running a test-pipe now.
