Fabspeed Motorsport USA's MaxfloCatback Exhaust System increases sportiness, aesthetics, and performance by replacing the rear exhaust section with a freer flowing extra light weight performance solution that saves a massive 18 lbs 8.2 kg.

SOUND:

The Maxflo exhaust coaxes out more of the characteristics of the boxer engine - a deeper rumble with a significantly more refined Porsche tone. This system is very livable with no droning, and the activation of Sport mode greatly increases cracks and pops during shifting and overrun conditions. Expect a slight increase in turbo sound as well - which can be enhanced even further at any point with the separate addition of our Sport Catalytic Converter. Finally the car can breathe and sound like a Porsche.

POWER:

Fabspeed's Maxflo Catback Exhaust added 4 whp and 11 ft-lbs of torque peak power gains when tested on our Dynojet on a stock vehicle. 8 whp and 11 ft-lbs at 3,500 RPM will make a significant difference in drivability. The increased exhaust flow helps tremendously at high RPM, unlocking 19 whp and 20 ft-lbs of torque at 5,000 RPM. To extract more power, we recommend pairing this system with our Porsche 718 XperTune handheld tuner

You won't be sorry
Size: 10.5-11.5 Women/9-10 Men, Color: Black
Great padding for comfort and terrific warmth. I bought a pair of Acorns 30 years ago and still have them. Updated to a new color and now feel the benefit of newer padding! I used the sizing listed for shoes and like the roominess for thicker sox. Well made and a joy to put on. (Wisconsin)

Extremely comfortable, leather sole. Hard to find a style.
Size: 13.5-14.5 Women/12-13 Men, Color: Navy Blue, Size: 13.5-14.5 Women/12-13 Men, Color: Navy Blue
Totally worth the price. This type of style is very hard to find, my husband had another pair a few years ago that he was never able to replace. These fit his wide feet and are very comfortable. The elastic at the ankle is not too tight. So glad I was able to find him a replacement. We bought the blue in a size 12. Love the fact that they are washable.

Very comfortable Slippers. Great buy!
Size: 12-13 Women/10.5-11.5 Men, Color: Charcoal
I bought these to replace a pair of slippers that I have had for years that are very similar to the slippers I bought, but I had worn a hole in the leather on mine, so I had to find something new and similar. These slippers are worth the money they are very comfortable, and I am sure they will last for years. They are a little tight around the ankle cuff but they are still new and I am sure they will wear in a little more when I start wearing them more.
