Active Autowerke BMW E9X M3 Signature X-Pipe w/ High Flow Cats

Active Autowerke is proud to release the highly anticipated Signature Track Pipe with X-Pipe and Connecting Pipes for the BMW E9X M3.

This exhaust system was designed and engineered to work with most after-market exhaust systems/mufflers on the market today without the need to cut, weld or modify anything. It is a true bolt-on that can be performed by most.

This system uses a free flowing 100 cell high flow catalytic converter.

Active Autowerke is able to improve on the factory X Pipe design by a scavenging effect that yields high horsepower gains. Dramatic weight savings are also gained when one compares the factory system at 40 lbs and the Active Autowerke Signature X Pipe weighting at a mere 25 lbs. Noticeable gains have been measured on the Active Autowerke Mustang Chassis dyno with a 12+ RWHP when adding this X Pipe to our Signature exhaust system and as much as 10+ RWHP when used to the BMW stock exhaust.

The Active Autowerke X Pipe system is constructed of 100% 304 polished stainless steel and has a industry standard warranty against rust. This latest addition to the Signature line up is a must for the true Enthusiast looking for performance increases.

FEATURES:

  • Free flowing 100 cell High Flow Catalytic Converter
  • Durable Polished 100% 304 Stainless Steel
  • Increase of 10+ RWHP
  • Completely Bolt on with Factory Style Flanges
  • Weighs 25 lbs. versus the heavy factory 40 lbs.
  • No Cutting Required
  • Weighs 40 Lbs vs. the factory of 55.1 Lbs.
  • Install to all systems that use factory style fitting
  • Two year warranty

Weird smell
Color: White-cooling Basic, Size: Queen(Pack of 2)
The pillows are great for someone looking for something cool and comfortable. We loved them so much that we bought a second pair. However, we were seriously disappointed with the odor of our last purchase. They give off a strong and indescribable chemical/burning plastic smell so nauseating that it’s difficult to sleep with. We’re hoping this issue will resolve with a couple more washes of the pillow cases, but am worried the source is the stuffing itself.

helped treat my sore neck
Color: White-cooling Basic, Size: Camping Pillow(Pack of 1)
This pillow — after dialing in the right amount of shredded foam — has greatly helped my sore neck. Initially, I had to remove some foam. Then I gradually added foam until it reached optimum comfort and support. It is also CPAP-friendly — especially when I position my head near the pillow's edge. (I am a left-side sleeper.) I like the travel size because I use a bulky hugging pillow to ease stress on my shoulder and elbow. That makes my side of the bed feel cramped if using a larger head pillow. A smaller pillow is easy to flip end-to-end in the middle of the night. I have spent lots of money on pillows over the years, but this is the best I've ever had for relieving [1] neck pain and [2] CPAP mask seal problems. Very comfortable, supportive, and affordable. I did not notice any unpleasant smell — and I am usually sensitive to that kind of thing. Would highly recommend.

Love them!
Color: White-cooling Basic, Size: Queen(Pack of 2)
Love them! After 10 years with our MyPillows, they finally lost their fluff. The reviews I read of the MyPillows of today were not good; they didn’t have as much filling as they used to. These pillows remind me of how fluffy our new MyPillows were 10 years ago!! You sink right into them and can mush them however and they stay. These are way cheaper than the Coop and it’s the same concept; add or remove the filling as needed. The cooling side is a huge plus too! You won’t be disappointed with these pillows!
