The Palenon Performance Valve-Controlled Cat-Back Exhaust is designed to give your B58-powered BMW M440i G22/ M340i G20 vehicle an incredible performance boost, enhanced sound, and improved airflow. Crafted for enthusiasts who demand top-notch quality and high-performance tuning, this exhaust system is engineered for optimal results and durability.

Key Features

  • Highly Tested: The exhaust has undergone rigorous testing to ensure peak performance and reliability.
  • Electronic Valve: Offers adjustable sound profiles with the convenience of electronic control for a customizable exhaust note.
  • Full-Pen Welds: Precision welding ensures maximum strength and durability of the exhaust.
  • 3 Times QC: Each exhaust undergoes three quality control checks to ensure the highest standards.
  • Great Tones: Designed to produce a deeper, more aggressive exhaust tone that enhances your driving experience.
  • Higher Flow: Optimized for better exhaust flow, which can improve performance and throttle response.

Fitment

This Cat-Back exhaust system is specifically designed for the following BMW models:

  • 2019+ BMW G20 M340i
  • 2020+ BMW G22/G23/G26  M440i

Optional Upgrade

For the ultimate performance setup, pair the Cat-Back exhaust with one of the Palenon Performance Downpipes for improved exhaust flow. The full exhaust package includes a stainless steel downpipe for maximum gains.

CEL Delete Kit (Optional)

When installing catless downpipes, a Check Engine Light (CEL) may appear due to the removal of the OEM catalytic converter. To avoid this, Palenon offers a CEL Delete Kit that includes O2 sensor spacers designed to comply with BMW's emissions parameters. These spacers install into the post-catalyst O2 sensor bungs, effectively removing the CEL without needing a tune.

  • Titanium Alloy: For even lighter weight and enhanced heat resistance, ideal for performance enthusiasts looking to reduce vehicle weight.

Good mop, bad avoidance
Size: C20 renewed, Size: C20 renewed
I have mixed feelings about this product: The good – It does in fact clean very well. The mop picks up dirt effectively and the vacuum works very well. It was also surprisingly good at swapping from carpet to wood. I have a high door mat and it ran right over that. It was also good at mapping rooms and positioning, the floor map and restricted areas worked nicely. App also works well. The bad – Obstacle avoidance, it has none. It will run into everything over and over. If the item is too light (shoes, mic items, etc), it will run up on top of them or push them. It will also get stuck if it runs over something. Cords have no chance. The lidar does not work for anything except a wall, and even there it was unable to deal with short trim (1” trim was too low for the lidar and it kept running into the trim). I was having to run around and ensure there was nothing on the floor for it to work effectively. It also had a lot of trouble with my dining table, it would spend 20 min bumping up against it trying to get everywhere. Overall – this is a great robot mop if your floors don’t have any items on them (or you can restrict any loose items to one area and make it a no-go zone). If that is true then this is a great mop for the price and I would recommend. In practice for me it turned out to be quite annoying due to its limited obstacle avoidance and was almost more of a pain then just using a Swiffer. Note – I had to return because it was making a scraping noise (refurbished version), that is not reflecting in my rating. Though I am also not re-buying due to these issues.

You do have to replace some of the moving parts
Size: C20 renewed
I love this for the price. I run it every single day, and it keeps mine floor, clean and free of hair and crumbs. I was skeptical, but pleasantly surprised. I even recommended this one to my sister. It’s nice not having to come home and sweep or vacuum the floor every single day because of the Pet hair.

Works great, easy to setup. It's my second unit for the basement level. Picks up all the fur from a large Rottweiler and a small Rat Terrier.
