Pro circuit makes a platinum 2 pipe that is for low to mid range without the over-rev. that pipe coupled to a shorty silencer would problably make a nice combination that your looking for.
I think he means the Doma. :thumb:
I
don't know how much faith I would put in magazine pipe shootouts anymore, the pipe shootout said that the Doma exhaust for my bike was a low/mid pipe with a loss in overrev compared to stock. It is in reality a more mid/top end screamer pipe compared to the stock but it does give good gains in the mid/top without much loss on bottom. What it does for the CR I can not personally say.
The preffered setup around here is the OC paltinum and shorty (the altitude seems to affect the pipes rated by the mags :o ), I run this on my '02 and like it, both the guys I know with '03's ae running it. I do know a fella running the Doma on his YZ and he likes it, but he revs his a lot more than I do. Re-jet carefully the case induction seems to be really finicky about pipe changes.
