01 996 stock header removal


Recommended Posts

:unsure: Hi was wondering if there is any pitfalls to taking off the stock exhaust

header pipes. I am installing Fabspeed Headers and mufflers and don't want to hurt anything. I already found the DIY article for the mufflers! :jump:

Thanks in advance (Great Site!)

IMHO anytime you change the intake volume or exhaust backpressure you likely need to adjust the DME. For minor changes the DME can "re-learn" itself (after disconnecting the batttery for 5 minutes). For changes that are more extensive you really need a good shop with a dyno to get the most out of the new setup. This also usually involves a programming change in the DME.

:huh: Loren How would one go about removing the ECU to be sent in for remapping?

Well, it might be best to have the whole car there so they can dyno tune to match your mods. But here is how you remove the DME.

Remove the DME/Relay Support 2 cover.

Best to disconnect the battery first then remove the 4 bolts on the metal cover and tilt up to unbolt remove the DME.

:D Thanks I would have looked under driver's seat like my old 89 911. Most of these places I have contacted want me to send it in. Although I found a place called www.eurospeedperfomance.com that is going to sell a unit you just plug into diagnostic port and reflash the ecu without taking it out!!
