lots of grinding to get the casting seams out but i think it was worth it . Just need to hit it with a little polish for that mirror look. What do you guys think? it would look nice with some silicone hoses i think.

 

Looks sweet!Wanna do mine?

 

I'll see how it ends up and i may offer it up to other people

 

Is this the stock piece that has been polished? Did you do any work on the inside?

 

thats stock.... why didnt u just make one with larger diameter(2.5 inches vs. 2.0 inches) and go hard piping all the way to the ICs.... no popping off of hoses....
either way, nice work

 

oh thats next for sure and in the works right now. I just want to drive the car now !

i am going to do the inside a little with light abrasive porting/polishing tools.

 

Rico; I did my "Y" pipe with a powder coating exterior but didn't polish it. The interior I did with "Extrude Hone" a company in Paramount. California. They use an abrasive slurry to polish the inner diameter of various items. The Inner Diameter came out very nicely.

 

Did the extrude honing help? I did the same to a Mustang intake many moons ago and it was a huge difference.

 

Seriously... I would consider extrude honing that YPipe and maybe having some heat reflective coating baked onto the outside if it made any difference.
