Default td04h-15g downpipe flange/new DP

So i have a greddy turbo kit that ive been dinkin around with for over a year and a week ago i decided for it be my pre new years resolution to get her runnin. i got everything i need to complete on the way and just need to put in Water Injection. the stock greddy pipe is lame and the one i got has dents and weld spots al up and down the dang thing. what i want is a new downpipe that will bolt up to my stock cat ( i know i need a high flow ) or if somone can point me to where i can buy a flange and make it myself. the ones on fleabay wont fit the 15g's. and my budget is 200$

Are you after the flange by the cat and the turbo flange? I got a tdo4h Subaru turbo and I just went down to a local engineering shop with 2 pieces of cardboard with the shape of the flanges.

5-8 minutes on a plasma cutter and pack of beers for the guy and I was smiling hard!

They just grabbed an off cut of metal and the plasma cutting is cool so the metal was barely warm even after they cut it.

(Dunno if that answers what you asked though)

We sell the flange for a Greddy Turbo. Give the shop a call (905)953-9260 and ask for John.

I would make the dp 2.75 inch or 3 inch if possible.

Good luck!
