Suggestion

Short of an expensive Porsche ducktail "Sport Aero" kit which would replace my existing powered up and down hardware, remove a button on my console, and leave me with original parts sitting in the basement until I sold the car..this was the most simple and elegant (not to mention cost-effective) solution I could find out of all the manufacturers.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1Original post

Tuesday at Benchmark Motoring in Seattle, we put on the Vorsteiner rear deck lid spoiler and Fabspeed Maxflo side mufflers. We left the primary Porsche muffler untouched with the factory PSE completely intact. It definitely feels like extra punch over 6000 rpm but thats my butt-dyno. Sound is tough to explain - it's like the 991 PSE before but has slightly more pronounced crackles and pops and it is more focused, if that makes any sense. It has a pleasant more-exotic (imo) resonance in normal driving that was missing before. It sounds good without the PSE activated now. PSE activated, it's a bit louder than before, not too much with just the side-mufflers..but now I really want to add the headers/cats. hehe. I don't have a good driving sound clip yet, just a few revs. I can't touch the center primary Porsche muffler if I want to keep the factory PSE intact. I can only do the side mufflers (now done) and the Fabspeed Sport headers maybe in the future. If you have PSE and order the Fabspeed side mufflers, make sure they know you have PSE because the pipe from the muffler to the exhaust tip is not the same as without PSE. We had to modify our Fabspeed pipe (cut it to proper length) to make the install work. It took all day. It was a bummer waiting for the pipe to be cut by a local muffler shop, but we got it done. Justin Karis at Benchmark Motoring in Seattle made it all work. Thanks, Justin. Factory 991 PSE + Fabspeed Maxflo side mufflers - YouTube Pics of the Vorsteiner rear deck lid spoiler:

The Vorsteiner pieces are always so tastefully done. I wish they made parts for 987s. Very nicely done.

Thanks a lot - I agree. Short of an expensive Porsche ducktail "Sport Aero" kit which would replace my existing powered up and down hardware, remove a button on my console, and leave me with original parts sitting in the basement until I sold the car..this was the most simple and elegant (not to mention cost-effective) solution I could find out of all the manufacturers. I'm sure it's not for everyone, but we are liking it!
