Very nice work!!

 

Wow man, they look really nice! I have the same question as jblack6527, how much coin did the project run ya?

 

Bluehayes and jblack- All the port work and smoothing I did myself, so only my labor. I have about 2 - 3 hours in each manifold. The only money I spent was the coating; about $150.00

1slow01z71- I have a few projects going on right now. These will probably have to go on a rear mount or NA set up as the coating should be different for a front mount because of the extreme heat. I will be doing a set just like these except coating them in a different coating for a road race car we are doing twin front mounts on.
I will probably put them on my truck when the motor goes in.

greentahoe- NA there will be minimal if any gains, but they do look alot better. For the rear mounts, it may help some by keeping the heat in to help in spool. My original intention was to do this to the manifolds; make custom Y pipe and coat that and everything else back to the turbo; partly for looks and partly to aid in spool.
To smooth them, I used a sanding disc on a 4" grinder. For the porting, I used a carbide bit. The porting was nothing compared to taking the bungs off.
