Mivec Point-Exhaust Noise

AMACHA · Post by **AMACHA** » Fri May 29, 2009 12:43 am

Ok two questions:
1: Does mivec changeover point need to be changed once you got mods on the car?
Hi flow cat,extractors,CAI?

2: Ever since i had the extractors fitted when it hits mivec or gets close the noise is a loud rattling noise like a zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz noise, before the extractors it was a deep bellowing scream wtf?

Question, does it actually rattle or is it more like a whine? If it is a rattle, something is loose. If it is a whine (eg like a SC whine, or Gilmour whine) then it is likely one of those funky by-products of less restriction.

Put my left nut on it that its the flex section in the collector pipe. Wrap the flex section in exhaust wrap & it'll shut it up. RPW's are notorious for it.

It will fix the problem only if the car is at operating temperature
