Jardine Exhaust dyno charts?

[YoTRacer158]

Anyone know where I can find some Dyno charts for Jardine exhaust? Specifically for a 2004 YZ250F? I've seen one for a YZ450F but that's it. Thanks in advance.

There was an article in one of the motocross magazines about a year or so ago that tested all the aftermarket exhaust systems on a bunch of different bikes. I was supprised to see that for the cost of the systems they sell the performance gains were very little. Most of the charts looked to give less than 1 hp gains on most bikes. I bet if you send them an email they will reply back with some information.

Yeah I sent them an email but havent heard back yet. I was planning on picking up an FMF system for my bike but I've been hearing lately that the Jardine systems are showing the biggest gains on the dyno.
