Twins piping-- where to get it?

Twoms piping-- where to get it?

Is there any place where you can get 4" and 5" piping for twins fabbing? How about radiused bends, etc. ? I could handle MIGging up some parts and all, but rolling my own sheetmetal and making the tubing seems a little daunting.....



Can you just take Class 8 exhaust parts and chopsaw, weld, hotbend, and fab your way to twins heaven?



I am going to be fabbing my twins when and if the time comes, and since I am using B-series chargers, I'll need to fab some crap.



I figure I can get the local machinist to fab flanges for me from 1/2" plate and weld the hot pipes myself. I'll just give 'em a template.



So, you guys who fabbed your own twins, where did you get the parts????

I am actually in the process of doing this myself...



I am getting the cold air pipe from NAPA... (exhaust pipe)



I also had a friend who works in a machine shop make the flanges for me.



Also getting some parts from ... http://www.airflo.com/muffler.html



Still searching for intercooler hoses.

go to any big truck shop and they can order anything you will need. it's usually cheaper than going thru napa.

The flanges you'll need are pretty easy to come by if you do some shopping... no need to have a machine shop fab them up...



Turbine inlet:

The small turbo uses standard T3 flanges...

The big turbo uses standard T04 flanges...



Turbine outlet:

The small turbo uses a standard 3" V-band flange...

The big turbo usually uses a 5" 1/2 Marmon flange...

OK Matt, you have told us what we need. Now tell us where to get it.

Do a search for Grand rock pipes,( grpipes.com??/) They are a heavy truck exhaust company, They have about everything, and will custom make stuff also. There prices arent to bad either.

It might be worth a call to PDR. They have a twin kit and will sell parts to complete your set up.

That's the same story I got when I was getting parts for Deo's setup.



CHEAP T3 flanges...



That figures... I go and post about T04 flanges... and now I can't find them.

FWIW a HT3B and B2 dont use a T04 flange. It's much wider.

 

[HoleshotHolset]

What is the flange size then?



I've been calling them T04's for quite a while... (my bad!)



I'm positive that the little turbos use a T3 flange, though... (at least I got that right!)

I dont know what the flange size is called for those two turbos. I would call Columbus Diesel and ask them. I know the B2 is a more common size than the HT3B though.
