uuhhh...what?
UHHH, you know, a down pipe that works with atr headers, w/t4 flange, w/4 bolt exhaust housing, one to fit something like this uhhhh

I got the email, thanks I will get back to you.
that was my point, I wan't trying to be a smart a**, 4 bolt or 3 bolt headers are the exact same except one has one more bolt hole with a rectangular flange instead of a triangular flange, neither of which effects what down pipe you run, only what turbo you bolt to it..... Its the exhaust housing on the turbo that determines what dp you are able to use. Maybe I misunderstood your origional question.?
Bump for more info. I need one too. The one pictured in the link is a dinosaur on center housing. Those dont flow much better if at all better than a 3 bolt. You want the tangential 4 bolt like in Terry's pic.

generally, with 4 bolt headers, you run a 4 bolt ex housing, which requires a v-band downpipe....unless u have an ancient on center
You mean you need a 3.5" DP like this one? I wish i could help you , but for the 20 hours labour its not really worth the hassle to build without a jig setup.
No.So all 4 bolt exhaust housing have v-band set up?
A mess!what have I started?![]()
