Thanks, I suspected that. Now I am looking for the person that has done this, I would like to try it if it works with the 2005 software.

Steve, I had the dealership add the PSE to my 2006 987S (with Sport Chrono) last Spring. I love it. We did not install the on/off switch that can be intergrated with the SC. Sounds great in Sport (loud) mode at all times.

Check pricing with Sunset Porsche. They have better pricing than Suncoast. A dealership will want to charge at least 4 hours labor.

Has anyone added the 2007-2008 987 Porsche Sport Exhaust to a 2005 or 2006 987 with Sport Chrono?

I have been told it can be done. I like the idea of the sport button adjusting the exhaust sound.

Then the last thing to figure out is if there is any ABS or PSM trobule with having the rear tires smaller than stock. I will talk to some independent techs.

Does this mean they chose 265/40 R18 instead of 265/35 R18 (which would have match the front diameter) for the stock rear tires on the 987S for ride "comfort"?

I have an 05 987S. When I look for used winter or track wheels, I always run into the problem that 987 and 987S rear tires are bigger diameter than the front tires. Example:

My car

987S Front - 8J x 18 RO 57 with 235/40 ZR18, 12.7in tire radius

987S Rear - 9J x 18 RO 43 wth 265/40 ZR18, 13.17 in tire radius

Other cars:

986S Front - 7J x 17 RO 55 with 205/50 ZR17, 12.53 in tire radius

98S Rear - 8.5J x 17 RO 48 with 255/40 ZR17, 12.51 in tire radius

911 Front - 8.5J x 18 RO 47 with 225/40 R18, 12.54 in tire radius

911 Rear - 9.5J x 18 RO 47 with 265/35 R18, 12.65 in tire radius

Tire calculators say not to use these other rear tires as the radius difference is more than 3%. Why are the rear tires bigger diameter anyway? Does this mess up the ABS and PSM?
