So, I simply can no longer overlook the 718 CGTS PSE acoustics. Yes, I have NA flat 6 exhaust envy, and realize my 718 will never sound like the flat 6.

I have not heard them all, but have yet to hear an aftermarket exhaust system that sounds significantly better than PSE. They all appear louder, but not convinced any provide better acoustics over the PSE. At least, I am not willing to drop $3-5K (plus labor) to get what seems, at best, marginal improvement in exhaust acoustics.

So, I have come to consider my best option is to ramp up the PSE decibels. Before pulling the trigger, I am curious to know if anyone has gone with the Fabspeed Sport Cat plus Max Flow True X-pipe combo?

I am confident this approach will ramp up the PSE decibels and not be associated with any additional drone . . . that I finally attenuated by disconnecting the Sound Symposer (aka Porsche Drone Device) after pulling the 7.5 amp fuse. In addition, I will be able to retain valve control.

What I do not know is if the indicated Fabspeed options will simply ramp up the PSE decibels - as anticipated and desired - or also significantly alter the exhaust acoustics (notes and tones)?

Feedback appreciated from anyone who has pursued the Fabspeed options mentioned.

Your best start for your goal would be replacing the catalytic converter with a higher flowing unit. Instead of cutting into your factory downpipe, would you consider a full replacement with optimized flow so that you can easily return to stock without drawing any questions? We use an HJS HD 200 cell catalytic converter as well.

You will not experience any drone with a sport catalytic converter and bolt-in X-pipe solution. You could even go catless and still have a civil cabin experience. The 718 has the benefit of ample sound deadening and a turbo to keep things quiet. With the sport cat you can expect primarily more turbo sound (add a BMC air filter to enhance that further), and a slightly sharper engine note. The volume will not be overwhelming. The burbles in sport mode will also be enhanced.

The X-pipe will smooth the exhaust note slightly and add a hint of extra volume. It won't be night and day on the 718. With our bolt-in x-pipe solution you have the benefit of a cast X-pipe which will never crack and you can customize the tips as you see fit with cut, color, and logo if you desire! There are a lot of false claims out there with no data to back them up, but most X-pipes on the market will flow very similarly, not hurting flow over factory, and while flowing more will not really impact performance.

I'm always happy to go over all options and provide forum pricing to give you a superior experience!

Thank you Mike . . . greatly appreciated!

How much difference in power/response does a Soul sport-cat/downpipe add? What if I also get the sofware tweaked to maximize the difference in back-pressure? Any additional advantage to the X-pipe?

Thanks,

FYI, I ran a fabspeed supercup exhaust on my 17BS which had the 200 sport cat. Sound was ok, definitely loud but terrible build quality and was always working on it to sit properly and stay tight. I had the car tuned and dyno tested for the exhaust, also had the car remapped at the same time (stage 2 tune). Car ran well but the exhaust was a big let down (even fell off after a track meet) I then had Porsche racing custom build a muffler delete set up. They used 70% of the oem exhaust, cut off mufflers and custom welded a super neat large diameter straight pipe with custom brackets. Car has zero drone unlike the fabspeed. Sound is very personal but the for me the tones through the entire rev range is just spot on. These 4 cyl motors develop a gorgeous, aggressive and natural acoustic full of heavy bass tones when released like this. Porsche racing run dyno tests pre & post fitment & consequently there was zero performance gain between the 200 cell Fabspeed cat and oem cat despite being told by multiple advisors it would. That’s because Porsche are clever bastards and the oem cat flows real well. I like how l am using most of the oem exhaust yet have achieved a very personalised and imho a great sound response. Interestingly enough when the cars not in Sports mode (which l drive in 90% of the time) you would be hard pressed to tell there had even been a muffler delete. The difference between the mode settings is significant which l really like. Cost was under 3k.

Hi there, super sorry to hear you had this experience with our Supercup system on your car. This is one of our top selling systems month after month with many satisfied Porschephiles but we always have our ears open for any "not so good" experiences that a customer has encountered. Our rigorous research and development process usually irons out most of it but occasionally things can slip through the cracks. Feel free to email us at [email protected] with any additional thoughts...

A common problem with any multi link type exhaust set ups l suspect. Under power (which the 718 has a bit ) bolt together type systems (like the super-cup) naturally work loose. A cars chassis will also alter under heavy acceleration and deceleration consequently anything else attached to it does also. If you drive your car hard you can’t beat a complete exhaust that’s been welded and secured correctly. I understand an exhaust made by such Manufacturers like yours has to segment the exhaust for shipping. It won’t matter how good or large you make your connective links / sleeves between each component the result will be the same. It will loosen under heavy load and or on b grade road surfaces. I commented on build quality as the exhaust mounts snapped. (Under engineered). I ended up getting a local welder to make some heavy duty versions which held up well. Parts that constantly work loose and then require the rear wheel to be removed to access the sleeves to retighten them got very time consuming & annoying. This led me to sort something that works and stays rigid regardless of the work the cars doing.

A one piece exhaust design isn't always great for a multitude of reasons. Old motor mounts can allow engines to sag (mostly an issue on older 911 Turbo cars), and the exhaust with it. Not having adjustment leaves you with no room for compromise. This is also the case for cars that may have slight damage and sometimes even the most professionally crafted exhaust can have variations between cars (sold different exhausts for over a decade). A one piece design can also put excessive stress on the mounting points resulting in sheering of hanger rods and cracking of flanges and welds. A lot of companies weld hanger rods to thin muffler cans. If you go too light on that weld the hanger rod can break off. Too hot of a weld and the muffler can will crack all round the hanger and yank off. I've had that happen on my share of systems on my cars . Flex sections help but they aren't always the end all be all solution. We designed our Performance Exhaust for the track and designed stress to be channeled into a mount on the transmission to help soak up stresses. A point of failure would be in that bracket or a clamp which is quickly and easily replaced opposed to a break in the system itself which would likely end a track day. We spend a lot of engineering time trying to reduce failures as we craft exhausts with lifetime warranties.

Hardware and the clamps sometimes makes a big difference as well. Too little torque on the clamps when putting the system together can definitely yield failures from heat cycling, and leaving too much of a gap on Torca clamps can lower the overall clamping strength. Not using lock nuts or the proper hardware can exacerbate the problem as well. Glad to hear you're happy with your custom solution!
