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.

  • Fits all Porsche 981 Cayman GT4 / Boxster Spyder vehicles (2015-2016)
  • Constructed from CNC mandrel-bent T304L stainless steel
  • Impressive power and performance gains

The best meat sticks!
Flavor Name: Wagyu Beef Steak, Size: 20 Count (Pack of 1)
These are the best meat sticks I’ve found so far! They are very clean and go down well. Very tasty. If you need more protein on the go-these are a no-brainer. Slightly pricey, but worth it!

Not bad. Read the box.
Flavor Name: Wagyu Beef Steak, Size: 0.8 Ounce (Pack of 10)
First of all, this isn't really beef jerky and nowhere do they state that it is. Simply put, it is not your typical beef jerky. I don't know how these are processed because there are not nitrates, nitrites, or even celery powder - which are the ingredients used for curing meat. Yes, these are ground and formed meat strips, just as it says on the box and on each individual strip wrapper. These lack all the extra preservatives and additives that other strips and jerkys have. And although some of the other meats that they have are flavored with cranberry, apple, or bacon, these don't have much flavoring at all. Just added honey, which keeps it from being totally vile. When I first opened the package, the scent was that of old time (not ancient) jerky. The way jerky looked and tasted in the 70s. But the flavor is really meaty/bloody tasting, with little hint of honey that makes it palatable. I'm not hating on this, it's rather not really too bad... just gotta get used to that bloody raw meaty taste. I've had their beef/bacon/cranberry bars and those were not edible. They were totally disgusting. Maybe it's because these are thinner and more like jerky (you get less of a mouthful) that I find them easier to swallow. I'v had quite a bit of their "bacon" bars (note, they are bars, not strips), and really wish they'd make the bacon bars thin like these strips as well. Although I like the bacon best, sometimes it's just too much... it's like spam but not as tasty. The texture of these is much better. Bottom line, if you expect these to taste like O'berto stips, then don't get them. If you expect something that tastes like a caveman's dinner, then this is it.

Meh
Flavor Name: Wagyu Beef Steak, Size: 20 Count (Pack of 1)
This is not beef jerky but rather and "ground and formed" meat snack. Not particularly rich, not particularly flavorful, and thus not particularly Wagyu.
