Factory Sport Exhaust

Recommended Posts

For '99 Boxster: Would like Porsche p/n's for the Porsche Factory Sport Exhaust and the required (I believe) adapter kit for a 2.5.

Also, anyone have the p/n for the 996 dash-mounted manual override switch kit that allows you to manually open/close the bypass valves on the sport exhaust? I believe this works on the 986 kit also. Anyone know for sure?

Here is the prior discussion on the switch. RennTech The TSB for the new 996 sport exhaust just came out in May. It does not list a switch kit, just a list of the many parts included in the sports exhaust kit. On the list of parts is 996 612 978 00 - called an electrical wiring harness - which includes a relay, switch-over valve, and some other parts. I think that is what is in Gert's picture

The TSB is clear that the actual switch is not included in the sport exhaust kit. The reason is that there are 2 different switchs, depending on where you want to mount it. If you have seen the switch in a LHD and RHD cars you would see the the tai pipe symbols are reversed. If you mount the switch to the left of the radio then the part number then it is 996 613 988 10 A05. If you were to mount the switch to the right of the radio, such as a UK car, then replace 988 with 987. Also, the switch is only available in the matt finish, not the gloss finish your 1999 has.

I am sure it can be done with a switch. One of these days I will ask Peter to look at a 2002-2003 996 wiring diagrams, 996 TSB, and figure out how to do it on a Boxster using the 996 parts.

The TSB issued in 2000 for the Boxster sport exhaust states that the installation kit for a 2.5 is included in the sport exhaust kit. The 2.5 kit is 000 044 200 09 - and include in the kit is 000 044 200 11 - the 2.5 installation kit. Check these parts with your dealer as the TSB is 3 years old and Porsche likes to change part numbers. Jeff
