live2themaxuk Posted January 6, 2007 Share Posted January 6, 2007 Hey all ok , few teething problems going throughthe motions of sorting them. Betweek 2000-2500rpm, especially as i blip and let off the accelerator as the revs come down, i hear a metalically butterfly noise from under the car, ( I THINK? ) i assume the exhaust. Almost sounds like a card in a bicyle wheel, but very mettllic-y. Not really a rattle more a fluttering . . . . . . You can hear it clearly when the car is coasting at 2000-2500rpm but nearer 2500rpm. Clutch doesnt have to be in or anything, its purely rev dependant. Its an 03 with 20,000kms and a Fujitsubo exhaust. Cat. . . .? Meow!!! any ideas Jamie Quote Link to comment Share on other sites More sharing options...
