I want to improve my 996 C4S a bit and was planning on putting on new headers and a new exhaust and air filter.

My qustion is what brands to stick on to? Does anyone have any experience in tuning a 996?

Also planned on lowering the car with H&R springs or would the Gemballa springs be a better choice?

Let me know what you´ve done with your 996.
