I am planning to replace all of the couplers (turbo, y pipe and intercooler) on my FD. With 80k+ miles on my car it is probably a good idea. I will use silicone hose from baker precision but I need to make sure I buy the right size. How many couplers are there total? How much hose do I need to buy to make that many? Are all of them 2.75"? I did a search on this but there did not seem to be a concensous and I want to make sure I end up with the right parts. Thanks!

I dont remember the size that I used when I did mine but 1 foot of it should be plenty long to do everything.

i think its 2.25, I've replaced mine 4 times in 2 days with some crap ones i keep getting at Home Depot.

I blew the factory one a couple weeks ago and my friend that works at Freightliner got me one. He got me a 3 inch which is a little big, so I'd say 2.75 is just right. I like it, even tho it's rubber, but it's corded so it won't blow apart. I figured if it can handle the boost on a semi, then it's cool with me.

2.75" is right, had to get another one recently. You can only use 2 straight lengths of about 4" each.
