Outer Limits 4x4 Board

Hey all, can anyone help me with where i can get intake duct parts from to do 4'' snorkel with rubber bends and all the pipe work to set up for a front mount? Im in east melb but are happy to pay postage.

Where do people get it all from?

Whats the best to use? (thinking stainless)?

About whats the cost of bends(rubber) ?

About hom much is it a meter?

Is all the ebay stuff as bad as everyone says it is?

Thanks for any and all help

When i did mine i think i paid about $15 for the bends from a joint in Tullamarine, Aero something.
Stainless pipe is the best to use for straights, but dont know how much it costs these days, prob like $20-30 a metre.
