PURCHASE DISCLAIMER: Fabspeed Motorsport does not condone the use of emission defeat devices for any vehicles used on public streets or roadways. Fabspeed Motorsport will not tamper, remove, disable, or bypass emissions equipment on a motor vehicle in accordance with 40 CFR Section 86.1854.12(a)(3), Clean Air Act 40 CFR 1068.101(b). This includes software, known as tunes, that reprogram a motor vehicles electronic control module to alter engine performance and enable the removal of filters, catalysts, and other critical emissions controls.

Fabspeed's SupercupTurbobackExhaust System for the 718 Boxster/Cayman is the ultimate solution for very aggressive sound and performance, with 3"/ 76mmmandrel-benttubing 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 andtrack-worthysound ensures you feel Fabspeed's difference.

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.

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.

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.

Why We Choose HJS Catalytic Converters:

HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light. If you'd like to learn more, watch our video about HJS catalytic converters.

Post-COVID Sock Hunt: Finally a Win
Size: Medium, Color: (001) Black / Black / White
Ever since COVID, I haven’t been able to find a pair of socks that hold up for more than a few months. Brands like UA, Adidas, and others seem to have cut corners—likely in response to inflation—by downgrading materials and labor rather than raising prices. The result? Socks that wear thin, rip easily, or lose shape fast. These, however, have been a pleasant surprise. I’ve been wearing them for a few weeks and so far, they’re holding strong. You can tell some cost-saving measures were still made—certain areas feel slightly thinner—but overall, the construction is solid. A key win: they stay on. These are ankle socks (not “no-shows”), and they hug the ankle securely. That’s a huge plus in a world where most post-COVID no-shows slide off halfway through the day. We may never get back to the pre-COVID quality standards without paying a premium, but for now, these are a reliable choice. Ratings: • No slipping: 10/10 • Price: 7/10 • Durability (so far): No pilling or loose threads — promising start.

Great Quality and Stylish
Size: Large, Color: (001) Black / Black / White
Exactly what I was looking for. I don’t like socks that are no-show that your ankles rub on the shoe. These are taller than that but shorter than socks that go up and over the ankle. They’re comfortable, good quality, and pretty thick. They’re form fitting m, but not compression. I dint like compression socks, and these are tight, but not too tight.
