monaco blue 172 ..
just wandering if anyone has had this problem before?
had a new zorst fitted about 2 weeks ago (standard from cat back) and when 6k is reached there is a high pitched whistling noise coming from the b/box was told this is because there hasn't been enough time for the carbon to build up yet ?????? which i think is bulls**t maybe wrong, but never had this problem with any other cars ive had.
and to top it off the middle section has developed an intermittant rattle,and all this from a 2 week old bloody exhaust ,, needless to say its goin back to reno satday for them to fix
