Good info guys, general consensus is port the stocker

 

I have a Megan Mani on the way and plan on porting the stock manifold, where would be a good place to have it done? Can just any shop do it?

 

good post, I just bought a megan mani, should get it in the mail soon. I still need the 02 housing, heard that the 10.5 hotside comes with some noticeable turbo lag.....anyone confirm this? But I will be porting out my stocker while the Megan is installed.

 

A header is only for non turbo cars. A turbo car replaces the header for an exhaust manifold and a turbo. I dont see any companies call the evo manifold a header.
