Greddy 15G Down-Pipe - 2" only?!
I've got the Greddy 15G turbo kit and the down-pipe is only 2" internal diameter... I am doing the rest of the exaust, including the cat, in 2.5" diameter piping. How much negative effect is the 2" down-pipe going to have? I am welding in the slash-cut tube for the crankcase ventilation today and finally had it out to measure... I had assumed it was at least 2.25" or so, but that is not the case.
As an FYI this car will be running at most 8 PSI. If I decide to go higher than that the DP will be upgraded to match the 2.5" piping behind it.

I'll be okay as long as it bolts up to the Greddy kit. Now that I know where to get it, I'll have it first and have the rest made to fit with it all at once.
