BMW introduced a new valvetronic, single turbo version of its direct-injection engine for the later F-Chassis models beginning in 2016 and continues into the G-Chassis models - the evolution to the S58 engine continues with the twin turbo variant used in the M-series vehicles. The Active Autowerke S58 downpipes for the X3M and X4M helps unleash some of the potential that is restricted by the OEM downpipes.

Turbochargers are powered by spent exhaust gases created during the combustion process. The quicker these gases are evacuated, the better. Unfortunately, the factory down pipe in the S58 is a bit restrictive, which results in slower exhaust gases and slower turbo spool.

The Active Autowerke X3M/X4M S58 Signature down pipe utilizes 3 inch diameter stainless steel piping in order to provide more power, quicker spool, and extreme durability. We've incorporated stainless flex joints and then down to 70mm to meet the OEM exhaust system. We never drop the diameter to smaller than the stock diameter of 70mm.

This variant includes a pair of 4.5" high flow GESI catalytic converters that will NOT produce a CEL!

The GESi G-Sport Ultra High Output Catalytic Converter features full 304 stainless steel construction, including the substrate. GESi UHO-Series Catalytic Converters are EPA registered and compliant in 49 states and fully OBD2 compliant, perfect for use on 1996 and newer vehicles. GESi proprietary precious metal loading technology ensures greatly reduced emissions, eliminating most "Check Engine Lights". These high flow catalytic converters outperform stock converters and provide a reliable solution to the most common catalytic converter problems.

The GESi UHO-Series Catalytic Converters are rated for engines putting out between 500 and 850 horsepower while maintaining a high flow capacity. The reduced back-pressure from this high flow catalytic converter will allow you to maximize your engines horsepower without the harmful emissions. Say goodbye to Check Engine Lights and failed emissions tests!

Not Perfect but Nice 👋
Color: Shiny Black, Green Lenses, Size: Large
Looks like regular sunglasses. 🤙 The AI is pretty basic. The responses are basic. Battery life is fairly good and the case as a portable charger extremely cool. Why did I get these? FOR THE CAMERA. The video recording is good. Good picture quality and this is the only camera glasses with image stabilization. When manufacturers make wearables recording video image stabilization is a must. Here its good. The footage is not shaky. But this coolness is only available in 1080p even though this records 2k or 2.7k. The app works fairly good but a tiny bit finicky as videos are not always loading to your gallery on phone or app automatically. The app in general is cool in creating some videos but again basic and limited with restrictions. The thing I don't like is connecting to an app which all these companies do to grab your data. Seems to be more about the app than the product. They only things that bug me about this is the 5min recording limit and the flashing light that is a distraction to the person being filmed. There are no blinking lights on our cellphones when recording. You can turn off LED blinking lights on all cameras but here they claim some privacy issues. When in public there is no right to privacy. When in private property and you suspect anyone recording with anything and you don't want it then say so other than than that there are cameras everywhere. They can record us but we can't record them? We don't need the blinking light and we need longer record times. I would like a seperate SD slot so I don't have to connect to my phone all the time to pull footage. These aren't waterproof so... This is a quality product with good audio and video. Interested in any updates to turn off the blinking LED and recording time extensions.

She loves them!!
Color: Matte Black, Clear Lenses, Size: Standard
Bought these for my daughter that is a content creator.. she does cooking and food reviews.. She absolutely loves these glasses!!!! They aloud her to free up her hands and not have to worry about holding her phone or using a tripod as much.. the video and picture quality is great.. I've heard her both listen to music and talk on the phone with them. They also look great on her. She is going to add her prescription lenses to them.. These meta gen 2 glasses are pricey ($322 plus tax on sale).. But if you creat content even at the regular price its a no brainer..

I use them daily
Color: Matte Black, Transitions Grey Lenses, Size: Standard
Enjoying arguing with the Meta AI, which is often wrong until you point it toward a current source of info. Bought them for the headphones, which, like the Xreal AR Glasses. Have an open air implementation that allows hearing stuff around you but playing music others don't hear. And the sound while having little bass, is quite good. The 3k hand free photo and video camera is a bonus, but only shoots in vertical, a stupid idea. But meant to push Instagram and Tic-Tic use. In 3k you can blow things up to 16x9 and have ok results. It also answers calls and will do as much as you connect it to. You get the phone audio over the glasses for calls, playing YouTube videos or anything your phone plays, whether an app the AI uses or not. I have Amazon Music and Audible attached so I can voice command them while driving, but Serious radio and YouTube music are fine, but you have to start them manually. The skip to next song glasses commands work on these apps too. Overall a very entertaining device.
