Man, I sure don't want to like ANY system that makes 4-strokes louder. You could say I'm Anti-Aftermarket when it comes too exhaust. I haven't gone away from stock on my last 2 thumpers, and the last exhaust I bought was a FMF Q (Quiet) pipe for the YZF250. That being said;
We installed the Big Gun "Race" pipe and can on Thump's CRF250 last weekend after turning a bunch of laps with the stock set-up. Left the jetting alone.
It pains me to say that it seriously woke that bike up. Much snapier throttle response and a lot more right off the bottom... just where the 250 needed it. The result was obvious... corners that required fanning, just rolled on. There was no significant difference at the top, although honestly I was riding hurt and didn't ring it out as much as normal. I'm sure Thump will add his impressions, I heard that 250 SCREAMING for mercy a few times per lap with him on it.
Bottom line; when the aftermarket companies learn how, or are willing to spend the R&D, to get this kind of improvement without the noise, we'll all live happily ever after. The gains were impressive.
Would I buy it? That's a tough decision. While I'd love to have the improvements, I think I'd rather not add to the noise problem. For the price of 4-stroke exhaust, I'm sure Mr. Gorr could hook me up with some head mods and a little larger piston.
