DSP exhaust

Does anyone have any experience w' the DSP factory series exhaust for the 426?

I'm thinking of buying one but I'm concerned about the noise. Can anyone tell me how it compares to a stock YZF pipe?


I've got their Ti full system. I have never heard a stock YZ, but mine is loud. It got much better after I repacked it, but it's still loud.


I run a DSP w/stainless steel header on my 2000 WR400. It is loud. I have considered getting a different system due to the noise. Also, you will likely need to rejet - I cannot seem to get rid of a dead spot at 1/2 throttle. Did I mention that it was loud?
