How is that possible when Nissan lists a SR20VE HP numbers at 187 at the crank.

For sake of ease, let's use a 15% drive line loss. That would put out ~162 wheel hp. The stock exhaust on a VE is smaller than 2.25", correct?

How is that effin' possible besides the fact that you said you did it.

So here's the real question. If I do go from my current 2.25 to a 3 inch system will I notice a difference? This is not a dyno queen I just want to drive it. If I won't really notice the difference I'm not gonna bother.

Does it mean 2.25" vs 3" exhaust is 30+whp difference?
