355 Exhaust Bypass valve

[Reggie20]

Just a heads up for 355 owners. I had an issue with the exhaust bypass valve not opening or only partially opening. I didn't realise but it is a common problem on these cars. I decided to purchase a Capristo bypass valve for about £450 ish. I took it to Rardley's for its annual service, mot and for them to fit the valve - no problems at all for them to fit the valve. When they took the old one of it was completely knackered - amazed it even half opened. We looked at the price of a geniune Ferrari bypass valve - £4,200😳 - could believe it and an inferior quality product. I know there is a 'Ferrari tax ' that we pay but 10 times an aftermarket price is crazy IMHO!

Yep, the stock 355 exhaust valve is known to seize or fail internally. £4,200 from Ferrari is a joke. Capristo is the smart fix better made, works properly, and a fraction of the price. You did the right thing.
