I'm in the process of doing a BHAF on my 92, I have the 4" tubing, and the BHAF, but I can't find a shop here in the 'peg that sells a 45 degree rubber elbow coupling in 4" ID. Anyone do this, or have leads on a shop/company, something??? I found some in the states, but I'm not too keen on bringing them in from that far. Thanks in advance.

 

How about these?

Check out Home Depot or any big hardware/plumbing store

 

Yup dems da ones! Stateside though. I'm thinking shipping, then Fed Ex charges and all that, won't be worth it! Thinking on a way to cut the OEM air hose and use that, I think it'll work, one straight tube into a 45 elbow to the turbo, keeping the air filter right where the air box used to be. Cut the box and cover to support the filter. Should work. Home Depot and all them have 4", but not in the elbow! Only straight! Maybe I can use PVC pipe, and call the truck the Plumber! Paint a partial crack on the tailgate.....lol

 

I would try a distributor for heavy truck parts. Freightliner, or Gregg Distributers.

You could go to your local auto parts store and buy some 45 4in exhaust and some 4in straights. The ABS stuff will work as well. Why spendbig the $$$ when you don't have to. Gates has decent prices on 4in air hose.
