Turbo flange pipe size

Turbo flange pipe size
What's up guys. I'm getting close to having everything for my turbo setup. I've decided to run a low/rear mount setup for ease of installation. I will run a 2.5/2.5 - 3.0 Y pipe that will be the merge basically.
My question is what size pipe do I need to use to fit it the turbo flange. Flange is a T4 open flange.
Also where's the best place to buy my j-bends and straight pipes? Needs to all be stainless.

Columbia River has always taken forever to ship/get parts to me. I used Ace Stainless for this last project and I was super happy with shipping time and the quality of everything.
Check out page 3 of my build thread for info on what I ordered and what not: https://www.performancetrucks.net/fo...-build-509803/
If your T4 flange is the oval/rectangle one you can make a 2.75" pipe fit, but a 3" will fit perfectly.

I have a gauge for that

You dont need 3" unless you have 600+ cubes.....friend of mine did a test with a 106mm turbo and a 450" engine, did tests with 2" up to 3" pipe and only made about 15 more hp (on a 2500hp setup), but moved the powerband up and increased lag drasticly. Basically, 2.5 is fine.

Dead on with the size of pipe. On my 427 w/106 it spooled at 3500 with 2.5 crossover to 3" merge. You want the smaller pipe crossover to increase exhaust velocity for spooling the turbo, depending on the size of turbo and motor.
