On the other hand besides using pipe fitting you could goto a pipe supply store and buy weldment fittings and then you dont have to worry bout grinding out the threads and having to deal with cutting threw that thick *** pipie to weld on a flange and the weldment fittings come with bevels on them for weld prep. to make welding easier.

heres my HMTurbo header made fomr weldment fittings.

 

looks good. i know thay had weld T's and 90's but they were pretty pricey. think they wanted $22 just for a T, if i was gonna pay that price i would just get the ---- from ace stainless or another site that sells that ----.

 

I did:

Slo_crx1 did it before me, for a 14b on his b16 a while back. That's where I got the idea.

You have to take some material off between the T's and die grind the threads. Bevel the edges too between the joints then fill the bevel with weld.

 

damn, almost makes me wish i still worked at a hardware store..haha

 

too much trouble for shitty flow. might aswell buy a ching chow cast manifold and get better results.

 

i tried tig welding those exact fittings together and that ---- is as bad a cast iron. the weld is cracked before you even pull the torch away. those are not weld els

 

heat with a rose bud torch till red hot then weld it

 

good idea...but i dont think its going to hold up.
