I (knowingly) bought it needing a clutch and RMS (which I've done) and replaced the IMS bearing as preventative maintenance as well.

Maybe slightly louder once broken in well or used with cat bypass and headers but I didn't want to wait.

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.

POST 1 / ORIGINAL POSTEROriginal post

Hello, I'm new to Porsche and a new member to this forum, but have searched this and rennlist for a few days and I want to see any RECENT feedback anyone has with this exhaust system. It's currently available for only $685+shipping. My 'new' car is a 2004 4S Convertible 6speed with 93k. I (knowingly) bought it needing a clutch and RMS (which I've done) and replaced the IMS bearing as preventative maintenance as well. The wheels are 19" OZ Superlegerra Thanks!

POST 2Original post

My friend as the AP exhaust on his C4S. Build quality is good, sound quality is also good. Personally, I don't think it's loud enough. Nor did my friend, so we "Gundo hacked" it to make it louder.

POST 3Original post

Since you're new, I'll explain the Gundo hack:

Ditto. If you wanna save some weight and like it on the quiter side, this exhaust would fit you. I would say it is 80% the volume of PSE. Maybe slightly louder once broken in well or used with cat bypass and headers but I didn't want to wait.

POST 5 / ORIGINAL POSTEROriginal post

Thanks for the input. I've heard the low-quality audio from the few youtube clips and it seems very tolerable. My main concern is with the specific fitment and relative build quality. One of my stock mufflers has a small piece rattling around in it that almost sounds like a whistle every once in a while...so I'm kind of using that as my excuse to replace them. Basically, I want to see if its a tried and true system that 'should' truly bolt right up with no issues. I'm sure I'll be content with the sound although I'm also sure that I MIGHT like the sound of a high-dollar $2k-$3k system a little more, they're just not in the cards right now. Also, the 996 does have aftermarket headers on it and the K&N intake as well
