2.25" is the stock size and 2.5" is the optimum size.

You'd barely notice a difference except for a bit of sound.
Most of the time, placebo effect dictates.

But without the extra 0.25 difference, how will we shave 0.001 seconds off our lap time around our block in the suburbs?Astron_Boy wrote:You'd barely notice a difference except for a bit of sound.

More air in, bigger bang (she said that, too) and more air out = more power...
Intake, compression, ignition and exhaust. Improving on any of those things = moar power, because physics and science.
(and that's what Mazda school taught me)

Don't forget the stock manifolds don't help with the air out. So I think the differences will be marginal.
