4in exhaust... every thing was built by me manifold, 4in down pipe, 4in exhaust.

the turbo is a he351cw. the cold side is a t70

i still need to wrap the down pipe and make lots of heat shields.

the motor is a 12a Large street port with a good exhaust port..
i had planed on running the 38mm gates on each runner but i didn't like where they had to be mounted. so now there is dual gates at the turbo flange should be fine. well anyways rip in to me let me know what you guys think or if you have any ideas

Looks good man. Always nice to see people do their own work. Where did you get the 4" piping? I'm thinking about making a larger dp to replace the 3" i originally made.

Interesting, whats the deal with the merge at the turbo flange? Never seen one like that before. I realize that its not a fully divided setup so they need to merge, but curious why you did it in a box format and not just simply dumping them into the open turbo flange?

ebay there is a seller that sells box of 10 or 12 bends for like 35 bucks
i can look up his name if you cant find him. he will put it up if you dont see something you want he has also got SS if you want to pay for it.

the holset i have like most in the road trucks(small trucks) is a t3 flange. so it is a collector to go from the 2 round pipes to 1 sq hole. it end up being a bottle neck of the whole system. so it will have to start compressing and pick up speed b4 the turbo (i hope lol) or it will slow things down abit and my dule gates are going to have to work alot. it should be good for the car its a DD it wont have to make crazy hp numbers. but it will be spooled very fast and can make upto 30+ psi not that im going to go that high. i should have a nice power band. guess i will find out

I thought that was stainless in the pic. My current one is stainless but i know 4 inch would be very expensive for ss
