i am working on a ihi rhb5 to std manifold setup, and i need to make a downpipe. i have seen beaus downpipes, but i dont think i can convince him to sell me one, so i would like to know where to get the flange for it. i saw it on a wrx site out of australia once but i cant find one now. any hints?

 

there was a guy selling some on ebay. try some places that specialize in WRX's for the flange. or you can hit up the junkyard, getting the flange is a bitch cuz its welded to the rest of the exhaust and you cant remove just the flange you need to hacksaw it off...

 

i have the cast elbow, but i dont want to squeeze down to that before my nice 3" exhaust.

 

off a MX6/probe? thats what i used. Beau cut it off about mid way down (i dont think it cleared the crossmember) and welded a 2.5 inch downpipe onto that. worked out pretty well...

 

i've got a link for his webpage, but i am not at home, i'll hve to post it tomorrow nite when I get back. pretty reasonable prices for the flanges.

 

*2.5 downpipe 2.25 exhaust with es oval muffler
*ported cx manifold
*mazda 626 IHI turbo
*wastegate set @ 8psi
*12:1 FMU
*inline fuel pump
*boost/airfuel gauge
*conquest FMIC with mod
*saab BOV
*custom charge pipes for know
*air filter came from the Honda Bike dealer
*NGK 2 step coler plugs

how much of a pain was it to weld up like that... that was my first plan, but i thought that by the time i ported it out (need it smooth on the inside)and all it would be a real pain. i plan to run around 10-12 psi if the turbo will do it.

 

the turbo will do it it, was easy to weld i just used mig welder worked great

 

this is Dustins setup.

thanks again Beau!
