Active Autowerke is proud to announce the release of our Signature F8X M3/M4 Exhaust System.

This system is the result of countless hours of R&D to obtain the perfect combination of performance and sound. Constructed of 100% 304 TIG welded stainless steel, we have created a modular exhaust system that will provide enough flow to support power levels way above the stock S55.

The stock S55 Midpipe is a dual pipe system from each turbo that leads to the rear muffler. The resulting sound is far from pleasant, and without any real scavenging effect the turbo lag is fairly pronounced. By converting to a single 3.5" pipe directly after the downpipes, our system promotes exhaust scavenging along with higher exhaust velocity to produce a quicker spool, more power, and a much smoother exhaust note.
We believe that we've built the best performing exhaust on the market. With the reduced back pressure and large single-pipe design you can expect exhaust velocity to remain as high as possible throughout the entire system. Our design is also capable of handling much higher power levels than stock. It's over engineered to have no issues handling the increased exhaust volume from extensive modifications including turbo upgrades. All Active Autowerke exhausts are designed and manufactured for performance, and our S55 exhaust is no different. Instead of copying the OEM exhaust, we started with a blank canvas in order to create a system as close to perfect as possible.

This Oil Definitely Glitters!
Color: Glistening Bronze, Color: Glistening Bronze
I really wanted to love this shimmer oil, but it's unfortunately not my favorite. I love that it has SPF! That is a big win for me! The oil is also very good at hydrating my skin, which I appreciate. My problem comes with the shimmer of the product. The glitter in it is too big for my liking. With it being called a shimmer oil, I expected tiny glitter that softly shimmers like shimmer powders, lotions, and oils usually do. But this stuff glit-ters! And because it's bigger sized glitter, it's a lot easier to see when it gets all over everything like clothes, furniture, spouses and children. If the shimmering glitter in this was just smaller and softer, I would love this for summer time to use on my legs and arms. But it's unfortunately just not my favorite and I don't think I'll be using it anymore.

Helps a lot!
Color: peach+urea
This helps with dry cracked heels more than anything else I’ve tried. Will order more. I put this on, then cover with a silicone heel cup for a couple hours.
