Fabspeed's Supercup Turboback Exhaust System for the 718 Boxster/Cayman is the ultimate solution for performance, with 3" mandrel bent tubing to reduce turbo lag and 36lbs / 16.4kg of weight while offering an invigorating increase in turbo sound and boxer rumble.

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. Worry not about drone as the volume level in the cabin is quite refined given the aggressive nature of the exhaust - this system is very livable on a daily driven car. 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.

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.

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: Fabspeed also offers 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.

Ewwwwww yuck awful
Color: Large - Obsidian Oasis
Gel moisturizer Sounds like a great idea right?? Ewwwwww! It’s so gross! They are hot feeling, sticky, and sooooo slippery. I was hoping to wear them overnight to help my dry cracked feet but you can’t walk in these! Not even to the bathroom. Honestly I wore them once, saw no difference, and threw them in the garbage.

The answer to calloused feet.
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
If you have dry callused soles, these are your answer. All my calluses left and my feet were very soft. They should not be walked in unless you are very, very careful as you will slip and fall. I stopped using them for a while and all my problem calluses are back, even when I use lotion at night. They tell you not to sleep in them, I don't know why. I do put these on at night and end up taking them off later as they're not comfortable to sleep in.

Slippery when wet!!!
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
“These moisturizing slippers are actually really comfortable and feel great on the feet. They’re soft, cozy, and do help moisturize while you wear them. I also think they’re a good value for the money. The only downside is that once your feet get moisturized, they can get slippery inside the slippers, so I wouldn’t recommend walking around too much in them. Better for relaxing and letting your feet soak up the moisture than for being up and moving around.”
