2009 CBR1000RR with mivv exhaust with custom made hi level link pipe, Last year at Brands it was 101 at 6000rpm with baffle in no issues Silverstone last year, failed static noise test which they wanted 105db at 9000rpm!!! it blew 108 at 9000rpm, after some moaning they let me on as long as I didn't trigger the drive by, which I didn't all day! Rockingham last year blew 102 with no baffle This year Silverstone no static but got told after first session I was 107db on drive by with the same setup baffle in, I had to make up a second baffle to put in and it was fine, I know that sound testing is a pain in the ass but this is starting to annoy me, What exhausts are people using at track days???? with two baffles I could notice a big difference in power and fuel consumption, has any one tried a decat stock exhaust?? Cheers
