Hi guys, the bypass valve is making (or causing) a heck of a rattling type noise when my car idles (weird, this only really started when i upgraded the exhaust to a straight through sports system) - my local mechanic, and mate, has informed me he's identified the valve as the cause and it will need to be replaced - Ferrari apparently quoting about 500GBP for new unit!! any other suggestions or potential repairs?? Cheers Doug
