My 997 has one and I hardly ever remember to use it . . . to be honest the difference between on/off isn't that much with the standard sports exhaust. If you want noise then you'll need to go after market Have you had it checked? Mines chalk and cheese and enacts sports mode so is also noticeable through the throttle. the electronic valves in the exhaust are know to stick or fail. just a thought.

aia Posted 18July, 2018 Report Share Posted 18July, 2018 Yes, I agree, when my valves are open there is enormous difference in sound, enough for the wife to comment about boys and their toys. Sounds like stuck valves Link to comment Share on other sites More sharing options...

Definitely chalk and cheese for me too. Especially when I added high flow cats. My one of the valves failed and was quoted 2k from Porsche to replace the entire muffler!! (valves internal so the whole muffler needs to be replaced I was told). I ended up removing the value flap inside so now its just always open. it's loud always which I don't mind... for now Link to comment Share on other sites More sharing options...
Dave997S Posted 13August, 2018 Report Share Posted 13August, 2018 Did the 997.1 convertibles come standard with the hardtop, like the 996 did? Link to comment Share on other sites More sharing options...
