These modular headers are the perfect solution for any Cayman or Boxster. Our patented RENNKRAFT™ modular design features a quick release V-band connector that allows the owner to easily swap between our German made HJS 200 cell cats and a cat bypass “straight pipes” for track use. RENNKRAFT™, translated from German is “race power”. These unique headers offer true street and racetrack functionality in an innovative precision engineered package.

SOUND:

Equipped with our 200 cell cats, you will get a louder exhaust note with a much more raw sound. Higher frequency tones are more defined, and off throttle burbles are more robust and transparent. With the cat bypass pipes installed, you're in store for a sound much more akin to a 911 CUP car than a Porsche street car. The volume isn't overbearing, but the sound is very aggressive and race bred. It totally changes the character of the car.

  • Constructed from CNC mandrel-bent T304L stainless steel
  • Impressive power and performance gains

Works as intended, but is badly designed
Style: Medium Room Air Purifier
This air purifier is great so far. I've only had it set up for about a day, but it seems to me that the air is cleaner so far. I got it for my office, mostly to make sure that there's less dust in the air because my allergies have been going crazy recently. The downside of this product is that the manual is just completely wrong. Both the manual + the box say to turn the bottom lid counterclockwise to open. However, I tried that and literally could not open it for the life of me. When I looked closer, I saw that there were pins holding the lid in place, and that the only place they could move was to the right - which meant turning the lid clockwise, not counter-clockwise. That wasted 15 minutes of my time trying to figure out, because clockwise didn't work either until I wiggled it. Likely the plastic surrounding the air filter was caught in the lid. Like another reviewer mentioned, the bottom lid where the filter goes doesn't really stay on tight, which is annoying. It took me a few tries to be able to put it down without the lid coming loose and the filter falling out. It's light in weight but very loud, at least when it comes to being on high (full blast). Medium is tolerable, low is preferable for whenever I'm meeting with a client. Sometimes I even turn it all the way off. It was maybe worth the price? We'll see if it helps my allergies.

Cable management

Used for cable management. It's really good for bundling cat5 and cat6. But I doubt it would be very good for towing a truck. Maybe use rope or a chain... I don't know I'm not a cop.
