What these pipes called?
loos like my same setup that i will be running in my 65 chevelle.. looking to be around 550rwhp on 8spi or so. they are not done yet but getting there. and these came from vibrant performance. they are very thick and seem like it will be strong but well see.
i still need to have them finished and then ceramic coated

I would only do that if there is no other option. I dont like the hard T, specially that close to the head. If I were stuck using logs, I would come of the head with a soft bend before going into the T. I preffer the stock manifolds and have a plan in my head already for a modified set with vbands on Joe's car.
The tubing is 1.5nom which has a larger inside diameter than stock manifolds. I'm pretty sure it is like or 1.6875" or something like that. You can run a 45degree bend on the flange to 2.5 nom tubing to make a more efficient log setup, for real cheap to
hmmm im going to have to talk to my builder and see why he did it that way.. i think it was b/c i dont have much room with the downpipe. and im only looking to be around 550rwhp. and im also using a/c if that matters.. i'll ask him saturday
^^^ well really the size doesnt matter so much because its all being forced through a very small space in the scroll of the turbo, but the ability for gases to make hard bends produces more restriction, resulting in poorer performance.
I made my own set of log manifolds for my setup. You can see a couple pics here - http://www.syty.net/forums/showpost....6&postcount=20
I just went 10.99 @ 125 a couple weeks ago on a hot day, 3800 lb truck, 10 lbs of boost, 93 octane, and street tires. I'd say they work just fine.
