2.25 vs 2.5

I have heard the arguments of going with 2.25" piping over 2.5" piping on a n/a application. But is there really a drastic amount of low end power loss?

if it made ANY DIFFERENCE it would be completely minimal.

Actually, you are talking about a section area of 3.397sq.in for the 2.25" tubing compares to 4.906sq.in. for the 2.5" tubing. That 1.509 sq.in difference is actually quite a big difference for just a @!#$ 1/4 of an inch. This is a great difference in the velocity of gas flowon a N/A car. Note also, that the smaller the engine the greater the change in tourque peak.
