Just a question : I would like to switch to a valve exhaust. The PSE from Porsche is in regulation with the EEC requirements with E-aproval, but it's very expensive. Therefor I would like to buy the DesignTek Valvetronic exhaust, but it comes without E-aproval. I was just wondering if I keep the stock exhaust tips, would a technical inspector actually notice the DesignTek isn't approved? Is the Original PSE system marqued somewhere with E numbers below, or is it just blank. Does it come with papers? Thanks!

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.
