Jamiie looks good in green.
1 question on AMA superbike configuration this year. Has there been a rule change as far as stock exhaust set-up goes? I see single sided exhaust on the GSXR and ZX. -

There is no rule. You can do whatever design you want. The only rule is sound based.

No problem. Actually the test is kinda silly. It's a SAEJ1287 based test (basically a static test, 20", 45 degree @ xx percentage of max rpm). Bottom line is that it can't be louder than 105 dbA. In many cases, that would be quieter than many aftermarket "street" exhaust systems based on those perameters. There are so many ways to get around the test and/or sound levels that it's not even funny. But then again, if you are in the pits and listen to some of the exhaust notes it can be surprising. A lot of the spectator bikes are louder than the racebikes! The Honda's are actually fairly quiet. Whereas the Ducati's last year weren't even close to 105....
