I crawled under the car and there are no vacuum lines or exhaust valves that I can see. I do have the sport option. I was under the impression that these valves are at the muffler. Are they visable from under the car?

 

Anyone try this with bypass pipes? My 13 GTS is LOUD on start up. Its actually too loud that im thinking about taking them off. I can't start the car without all the doors shut or else i scare the crap out of my passengers.

 

I have the Turbo with the sports button on the console. I went under and cannot find the valve at the tail pieces. No valve or tubes. Am I looking in the wrong place? Shouldn't I be able to see it from underneath? Do I even have a valve? Help!!!!!!!!!! I am gong to do the secondary CAT delete this weekend.

 

With mine that only happens when I start using the accelerator.

The engineer that made the console/door 'oh shnit' handles deserves an award for well made they are.

I agree though, and I have the PSE option, the level of noise gets old pretty quick. I tend to quiet mine down when coming home later in the evening or on long drives. The drone gets annoying. However, hitting that switch before passing... gotta love the >BLAP< the exhaust makes at shift points as you pass someone...

 

I dont mind the noise after the car is running. But is yours LOUD on start up?
