Its just one of the quirks with the XR5, they bang when you short shift on upchange, and they bang on downchanges
Its louder with an exhaust, but you should hear it with a turboback!
edit - hey I forgot to mention, we've lined up a night to go to WSID. 10th June, if anyone's interested.
More details can be found here, but you need to joinup, so come and say hello
