I have a 2004 YZ450F with an aftermarket BigGun exhaust. It currently has a spark arrestor on it. Would removing it give me a noticeable improvement or not for when I am running Grand Prix's?

Based on my experience with my DRD systems, you wouldn't know if it was there or not in a blind trial. Makes no perceptible difference.
