Default F22b2 turbo downpipe

So I picked up a little 94 Accord for a beater turbo project. I figured it would be similar to a civic. Did nooot realize the clearance for the downpipe was going to be so tight going past the AC compressor on the driver side.AJP distributors used to make a good one but no longer caries it. Looks like I'm gonna have to fab one up. Anyone mind posting some pictures of what they have put together for a t3 flange turbo setup?
Thanks in advance

You need a very tight radius to clear it with the turbo exhaust outlet pointed that way. Multiple pie cuts are generally used. If it's a small frame turbo you can flip it and still have hood clearance to make downpipe fabrication easier since it's pointed in the other direction. This requires moving the wastegate though.

I recently built my own downpipe it took 17 different pieces cut and welded. But now I have tons of clearance for ac and alt. Also I used a ac compressor manifold & line from 98/02 for extra clearance. I've got a f22b1 in a 97 accord wagon.

I picked one up from ajp distributor. Gotta say the fitment was pretty much on point. Although I would like to get a bit more ground clearance. I'm thinking of trying to fab some brackets up like hasport, so I can adjust the engine grind clearance, but for right now, I just raised my car up half a inch or I might even go higher. I'm getting a bit older, so I tend to shoot for more comfort and reliability and function. I street tuned it myself on honda tuning suite. Its up to 10-11 lbs on the stock map sensor. But I love the power gain, definitely enough for me. It breaks the tires loose at the top of third gear yesterday.. I'm also on a completely stock exhaust besides the 2.5 down pipe..

I'm using a flex pipe dump tube adapter, its really useful. You can bolt it up straight to the wastegate flange and there's another adapter piece you weld to whatever spot on you down pipe and just screw on the flex pipe to it. Or just route it somewhere to open atmosphere.

yup, I'm just about to start on other parts of the car, like upgrade my coilovers for some tein fully adjustables, and work on fixing small things here and there.. need to raise the car up a bit,, the ground clearance is horrible with a 2.5 downpipe. Thats why I want to get stiffer suspension and longer shock travel. But she's running good on 10 lbs. Ill be trying to raise it up once I get another map sensor. Goal would be 15 lbs on a daily driven setup. My guess would be 300-350 whp on that psi.. since drivenfilms on youtube has a f23a on 15 lbs and it made 350 fully stock.
