Re: Opinions on IC piping
Well I can't answer your question but, for comparison... My cores openings are at 2.5. It is 2.5 from the IC to the TB but, the pipe from the other side of the IC is 2.5 then tapers down to 2 inches and then to the turbo. IMO I would go with 2.75 piping.

Re: Opinions on IC piping
Get a reducer coupler to go to 2.5". The only people really running 3" are running massive turbos. 2.5" is the way to go.

Re: Opinions on IC piping
Do they even make 2.75 piping? I don't think they do, I think its either 2.5 or 3. And 2.5 will do you just fine.
