Aftermarket Exhaust
elfresco replied to 9971830's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)
The stock headers on the 997 are designed to deliver more than 2x the air required - you will see no performance gain by changing headers. Be skeptical of anyone claiming you will see more hp on a Porsche from new headers. Many aftermarket exhaust systems sound "bumble-beeish". I have yet to hear anything better-sounding than the Porsche Sport Exhaust System. You would be well served to compare the sound in person and judge for yourself. I'm skeptical in general of any gains in hp claimed by the manufacturers of those aftermarket systems; after all, they want to sell you their products. I would insist on seeing before and after dynos from an INDEPENDENT mechanic, not the manufacturer, dealer, or installer, of those systems. I would need some assurance that the dyno was not recalibrated to bias the results towards the aftermarket equipment. -
Wiring diagram for auto-dimming rear mirror
elfresco replied to elfresco's topic in 987-1 Series (Boxster, Boxster S)
Yes I am talking about the interior anti-dazzle mirror on a 987. On the 987 the pin assignments are not labeled, and there are no striped wires on the wiring harness... just solid white, black, gray, yellow, and brown. On the aftermarket mirror for 986/996 they are at least labeled as 12V, IL, GND, RI, +0, -0. Any way for me to tell which is which? -
I'm looking for the pin assignments for the auto-dimming rear-view mirror that comes standard on a 987. There are 6 pins; 1-5 are used; 6 is blank. Here are the wire colors if this helps: 1 - White 2 - Black 3 - Gray 4 - Yellow 5 - Brown 6 - NOT USED I presume these somehow correspond to: 12 V Ground Reverse ? ? I'm not sure of which is which. Is White 12V and Black ground? Can anyone with access to a wiring diagram help?
