Very well could be, I went from a JP-4 to a 2050 (borrowed from TKO's Peter Martin) on my V-spec, and holy cow what a difference, it gained an extra minute and also ran with alot more snap and top end. So far I am not impressed with the JP-4. I am really dissapointed in knowing that I may be looking at $125 for a pipe, but I couldn't believe the difference it made.

Chris went to a 2060 on his 5 port from the 086 and it woke it up as well, but his mileage was about the same.
