Port Exhaust Manifold?

[dakmon]

I have a 1st Gen. Talon Tsi and have installed a 2nd Gen. Ex. Man. Do I need to port the manifold in order to go with a 3" exhaust? I will be upgrading the turbo in the future and want to know if I risk boost creep by not porting the manifold. Thanks for any input.

Nope. If you want better flow, port it.

Ya you don't need to port it for a 3inch exhaust. But it always helps to port it.
