I really enjoy what I did which was remove the secondary cats with some random test pipes I got for like 90 bucks and do the fister mod where you weld a tube from the inlet to the outlet of your exhaust.

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

Hi everyone, could you help me decide which upgrade is best for my 2001 Porsche 986 Boxster 2.7? I’m looking to improve the sound of my car, and I’m torn between two options: 1. Porsche Exhaust Sport part # 996-111-141-05 , I can’t copy/paste the link here but mother sierra dot com has it on their website! 2. Fabspeed Porsche 986 Boxster Maxflo Performance Exhaust System (listed here): https://www.fabspeed.com/porsche-986-boxster-maxflo-performance-exhaust-system-1997-2004/?revpage=2%20#product-reviews I understand that these are different upgrades—one is a muffler, and the other is an exhaust system. Although the price difference is significant (double), I’m leaning towards the Fabspeed exhaust system, but I’ve heard that it may not be worth it for a 2.7-liter engine. I’m also considering the Dansk Sport muffler as an alternative, as long as it provides some additional sound. However, I don’t have any specific references or opinions on this, so I was hoping you could share your thoughts. I know there might be other options available, but for now, these are the two I’m currently debating. I appreciate your help and look forward to hearing from you. Thanks in advance!

POST 2Original post

If you are looking to replace your muffler, you could try this mod first as you would have nothing to lose. Although I have to mention I did it on my 2.5L with a 2.7/3.2 muffler and I found with stock cats there was no change. Only after installing 200 cell cats could I hear the difference.

POST 3Original post

What do you mean it might not be worth it for a 2.7? Are looking for an aggressive sound or performance? There is minimal performance from an exhaust upgrade only. If it is sound, then you want a top name brand system as many of the cheaper versions will have you ending up with a drone sound that will drive you crazy in the 2500 to 3000 rpm range (final drive rpm range) but sound great in the higher revs for a short period of time. If you use your car for any longer drives, the drone will have you wishing for the stock exhaust. I ran a Borla system with catless headers on my Boxster S and had to take it off. Went back to stock and am much happier.

IMHO, it's better to invest on a good quality exhaust that you can always sell afterwards if you end selling up your car. Personally, I have fabulous experience with the SpeedArt (sound version), sold in the USA as..? (sorry brain fart..), but her name is Rhonda, she is in FL I will get back to you as soon as I remember her company name.. PS: Fabspeed has good reputation as a No drone exhaust ..(I would stay away from Borla..)

FVD Brombacher sound version? I'm very happy with mine paired with 200 cell cats, but looks like it's price has almost doubled in the last four years.

POST 7 / ORIGINAL POSTEROriginal post

Thanks for all the inputs so far! Does anyone have any information about the Dansk Sport Exhaust? Here’s the link: https://www.heritagepartscentre.com/us/pc1110076-sports-exhaust-rear-muffler-stainless-steel.html?gad_source=1&gad_campaignid=20951594081&gbraid=0AAAAACmlvQK1VCHV6OJevQyua7r4fvKKb&gclid=CjwKCAiAkbbMBhB2EiwANbxtbYfj6V4zWsKIbduZ4kxs iqWKbfmE_-cZOiA7zknkWCCqPKXyf26UQxoCwmMQAvD_BwE I can easily obtain this exhaust here in LA. I’m just trying to understand if it actually enhances the sound of my current single-pipe stock exhaust.

YES..! It was FVD Brombacher :-) That is the company that I was trying to remember, I bought from Rhonda the "sound version" for my 987CS and was Very happy with it, with literally Cero drone, and sadly, a few years later when my car got totalled (T-boned..) I sold the exhaust, coil overs, OS Giken LSD, IPD plennum, etc, If I remember correctly I sold all the components fairly quick roughly at half price of the cost when they were new. the only things that I kept was the Tarett rear toe links (assumed that they were gone but saw them the other day on the garage)

I have this one and really like it. Notably lighter weight and a more compact size. Sound is a subjective parameter, but to my ears it offers a nice improvement over stock.

POST 10 / ORIGINAL POSTEROriginal post

Thanks so much for the input, @Dave80GTSi ! I’m very close to pulling the trigger on this one, so any additional information is priceless—especially since there’s very little out there and even the vendors don’t seem to know much. This is where the community really shines Do you happen to remember if this is a straightforward swap, or if any additional parts were needed? From what I understand, it seems like a direct bolt-on, but I’d love to confirm. As for the sound, I completely agree it’s very subjective, but since you’re running it, could you share a bit more detail? Is it louder mainly on startup, at certain RPM ranges, or just overall louder without being obnoxious? And have you noticed any drone at cruising speeds? Really appreciate your help!

This Dansk muffler is often referred to as their "sausage" muffler. A search on this forum using that term will likely bring forth a series of past threads for you - many likely to be from me! (If not, feel free to search under my user name and some key words such as "exhaust", "muffler", and so on.) A very straightforward DIY installation, a direct bolt-on. Could not be easier. You will be amazed at the weight of the OEM muffler once you remove it. Just slightly louder than stock at idle, not obnoxious, very neighbor friendly. It is when you put your foot into it that it sounds at its best - a nice Porsche-y growl. No drone to worry about. You'll love it! I bought mine used. The dents that you see in my picture below were courtesy of the previous owner (cosmetic damage only, no performance effect). DM
