does anybody make a aftermarket turbo elbow and downpipe for the greddy 15g? I've searched but could not find anything.

You can find a flange on ebay for a 15g exhaust housing. Have fun paying for a custom welded downpipe. I just used the greddy exhaust housing that's a/c compatible and hogged it out to 2.5in(of course the manifold was ported out too), then paid a good shop to weld me a 2.5in downpipe to fit my reverse mounted greddy 15g set up that makes 189whp/179fttq on 7psi and stock d16a6 mpfi, Z6 IM, 9.6:1 compression (with boned-spec trans). I need a built block...

Even hogged out, the 4th bolt thru the elbow makes it pretty restrictive. Kteller makes 2.5" downpipes though, that will definitely help

The kteller downpipe is over priced, and you'll still have that restricted cast iron elbow. Get a ebay flange and go to a good muffler shop to have a real downpipe made. This is exactly what I did, and my turbo spools really fast pulls hard at 13 psi.

how much power are you making at 13psi? also from your sig it says u have a web stage 1 cam. do you have a before and after dyno with that cam? i have a jdm d15b myself.

I have never dynoed my car, I'm thinking it's around 225 at the wheels according to other builds and dyno sheets I've seen with the same engine/turbo combo. Bone stock block with ARP head studs lol.
