I see a lot of these for the 997.2. Does fab speed or sharkwerks make these for the 2007 997.1?

I misspoke. I am looking for the ones that bypass the middle muffler. And then connects to the side mufflers.

 

The primary muffler bypass pipes.

 

The 997.1 does not have a center muffler like the 997.2 so there is no need for a bypass on your car.

 

Oops. Guess I should do more research. I have factory PSE. Love the sound. Would like to know what can be done to enhance the sound. Without negating the PSE.

 

PSE sound is perfect the way it is IMO. I have mine open all the time and I love the way it sounds any speed. Rumbles at lower RPM, nice deep sound above 3p RPM. Best of all, no droning sound!!!
