Yes, about $2500 for PSE, including the dash switch, and $895 for a Sharkwerks center muffler bypass. Do that, and you're there. You can also have the side mufflers converted by Fister.

 

10 year old thread brought back to life but I'll bite since the question is still valid although a bit confusing and may remain unanswered or the answer unclear to some. The center muffler has nothing to do with PSE on the 997.2 cars. The side mufflers are what makes the difference between a PSE and a non PSE 997.2. You get that center muffler with or without PSE side mufflers.

With a PSE car the easiest, least expensive and one of the best (imo) solutions is to simply replace the center muffler with any of a number of center bypass options available. I have the Sharkwerks pipes and love the sound in combination with the PSE side mufflers. Of course you can replace all of it but the PSE mufflers sound really good with the center muffler gone and you retain the loud/quiet option with the PSE button on the center console. Remove the PSE mufflers and you lose that option.

For a 997.2 car with non PSE side mufflers and the center muffler still in place I'd be tempted to buy a Tubi system. Had that on my -09 C4S and it was killer. Replaces both the side mufflers and the center muffler.
