Current Stock:

Fabspeed's Supercup Turboback Exhaust System for the 718 Boxster/Cayman is the ultimate solution for very aggressive sound and performance, with 3"/ 76mm mandrel-bent tubing to reduce turbo lag and immediately remove 36lbs / 16.4kg of weight from all Cayman/Boxster 718 cars while offering an invigorating increase in turbo sound and boxer engine rumble. Increased throttle response and track-worthy sound ensures you feel Fabspeed's difference.                

SOUND: With Sport mode activated burbles and backfires erupt in abundance on overrun, and downshifts summon a bark that will make all eyes and ears around focus on you. The factory exhaust mutes the turbochargers, the free-flowing Supercup reveals their presence with a very pleasing increase in spooling sounds, adding more character to your driving experience. The boxer engine rumble is enhanced and refined in a distinct Porsche tone. This system is aggressive and maximizes power while also removing unnecessary weight from the LEFT side of the car. 

FINISH: Full polished T304L stainless steel, beautifully welded together and finished off with hand made T304L single-wall stainless steel tips or premium carbon fiber shrouded tips which fit the rear bumper of the 718 like a finely tailored suit.

PREMIUM HJS HD CATALYST: Fabspeed Motorsport is the largest distributor of premium HJS catalysts in North America, and second largest in the world. Based off years of engineering experience and ample testing we've selected the ideal catalyst to unlock performance from the factory exhaust system. This German imported 200 cell HJS HD catalyst is the top of the line solution to increase exhaust flow, resulting in a satisfying increase in turbo sound to match the extra horsepower gains. This specific catalyst has proven itself in numerous Ferrari and Lamborghini applications - able to withstand extreme abuse while preventing any check engine lights. The HD designation signifies the incorporation of a brazing stripe and special mantles to hold the metal matrix in place through the toughest of conditions while ensuring the overall integrity of the catalyst. The best part - increased performance without a check engine light. 

CATBYPASS PIPE: We also offer the Supercup Turboback without a catalytic converter for those looking for the most aggressive exhaust in terms of power, exhaust volume, and turbo noise. A check engine light can be expected due to eliminating the catalytic converter. The CEL occurrence can be reduced/eliminated through the use of our O2 Spacers or upcoming tuning solutions. Fabspeed Highly Recommends an ECU Tune for proper vehicle operation and to eliminate any possible engine or hesitation issues. 

POWER: The addition of Fabspeed's Supercup Turboback Exhaust System with Sport Cat added 10 whp and 13 ft-lbs at 4000 rpm as tested on our Dynojet. Expect more power and response with our Catbypass option. The Supercup Turboback is a very free flowing system and full potential will be realized with a tune. We look forward to extracting even more power with our hardware in conjunction with a Fabspeed ECU Tune at a later date as soon as possible.

    Awesome Performance Upgrade and Sound

    Posted by Bob W. on 1st Mar 2018

    FabSpeed installed the Supercup Turboback exhaust system and a BMC F1 performance filter on my 718 2.0L Cayman. From start to finish the whole experience was excellent. Alec was very knowledgeable and excellent to work with in getting the purchase and installation set up. I spent the morning at FabSpeed during the installation, which I highly recommend--it's just a very cool place to hang out. Alec gave me the full tour of their shop and manufacturing capabilities. The installation was very professional and very well done. I was able to see the car on the lift at the various stages and the technician explained everything as he went. I also received a short lesson in removing trim and access covers in order to inspect and clean the new BMC air filter. Following installation, the difference in sound quality was amazing between the stock exhaust and the Supercup Turboback. It was everything I had hoped for including the increase in power and responsiveness. The turbo spools immediately with no noticeable lag, and results are awesome. The sound quality is amazing in both normal and Sport modes. FabSpeed even boxed up my stock exhaust for me and shipped it to my house for storage in case I ever want to revert back to the stock configuration--that's not going to happen as long as I own this Porsche. Great company, and great product.

    Night & Day Difference

    Posted by Todd F on 4th Dec 2017

    As a returning customer, I had high expectations for this product. I owned the car for a few months prior to putting on this exhaust, so I was familiar with the stock exhaust system. After receiving it, and the installation was complete, I was overjoyed. The exhaust tone, and sound was completely different than stock. It opened the car up quite a bit, and it's very nice to be able to adjust the tone via the Sport and Sport Plus options. The only issue I had with the system, occurred near the tailpipes themselves. The original bracket that Fabspeed provided was not strong enough, and after contacting them, they immediately shipped me out a new and revised, and much stronger bracket. It was easy to replace, and it is completely solid now. The kit looks very professional, and actually has great fit and finish. I would recommend this to anyone that wants to upgrade their stock exhaust.

    2017 718 Boxter S Exhaust

    Posted by Anonymus on 27th Nov 2017

    I purchase Fabspeed Supercup Tuboback system two weeks ago. I install my exhaust system last week and I can tell you its the best bang for the buck. The system not only shaves 36lbs, it sounds awesome and quality looks great. It sounds much more aggressive and make my car spool faster, thanks to the 200 cells sport catalytic converter. I purchase Fabspeed valvetronic exhaust for my 2015 M4 last year and its worth it. Thank you Travis for great customer service. Happy customer =)

    Review for Fabspeed 718 Boxster S Exhaust

    Posted by Todd F. on 18th Jul 2017

    We purchased a 2017 Porsche 718 Boxster S in August 2016. We ordered several options including the Sport Chrono Plus, which allows a bit of a different exhaust sound directly from the factory. We otdered the stock exhaust, not the factory sport exhaust, as we knew we were going to get the Fabspeed exhaust installed after purchase. Fabspeed is noted for their precise engineering and high-quality. We were still pleasantly surprised by what a beautiful exhaust system this was when we received it. It looks like artwork. But.....How does it work? We are completely enthralled. My wife is not a fan of what she calls obnoxiously loud exhaust, but this one has such high-quality sound that she actually enjoys it even in the sport setting. When in normal sport Chrono mode, exhaust noise is quiet enough to come home at night without waking up the neighbors. It also seems to get a lot better gas mileage, although that may not be dependent on exhaust as much as the ECU programming. When in the sport mode on the Chrono plus setting, the exhaust is everything I had hoped it to be. I'm a fan of a much more emphatic exhaust, and this is both a masculine and throaty sound. It does not drone, nor does it vibrate at all. You will definitely know it's there, and I did post a couple of videos on this website as well both of a drive-by & and in cabin video recording. The performance of this car is quite exhilarating even stock. After the exhaust was installed, it's truly a beast. I recommend the exhaust unequivocally. If you don't like it loud, you can use the normal setting and still get great performance. Todd F.
