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.

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.

Half gone in the first 45 minutes...
Size: 6 Inch, Color: Bone
our medium sized dog is an aggressive chewer but we expected mire than 3/4 of an hour before the bone's demise. Half gone quickly, heavy stitching included, so threw away the second half for fear of a blockage. Not safe, not durable, disappointing. Sorry, cannot recommend this one.

Puppy loves it!
Size: 6 Inch, Color: Bone
I have a very energetic lab puppy - this chew kept her still for longer than any other toy I’ve tried (besides bully sticks and peanut butter). Highly recommend!

Good for an aggressive chewer
Size: 6 Inch, Color: Bone
My dog loves it. These last a long time. My dog is a Rottweiler/American Bulldog mix, she goes through a lot of toys. So, I try to buy her something that has no stuffing, but will keep her from getting bored. This one has lasted about 6-7 months, the leather is chewed off, but it's still the shape of a bone. I did just order another though, the one she has is a little stinky from her slobber. :-)

Not as expected
Size: 6 Inch, Color: Bone
I have been looking for these ever since we got a similar one at Sierras for our 1 1/2 yo Cane Corso. She is brutal on chew toys and the first one from the box store held up well. However, this did not hold up as well and she was done with it in less than a week. Still looking for that perfect toy.

More durable than expected.
Size: 5 Inch, Color: Raccoon
I was walking through my front room the other day when I noticed a suspicious spot on the floor. It looked like something I should not touch without gloves. As I got closer, I realized what it was. It’s the ‘guts’ from this toy. My dogs (Pit Bull and German Shorthaired Pointer) were each given one. Both are aggressive chewers with their toys. They ATE the faces off these toys and now play with the felt interior. I’m still trying to figure out how they ate through leather while the felt remained intact. Regardless, they still play with them. Now they are basically semi-fuzzy throw toys we can throw in the house because they don’t leave marks on the wall if our aim is off. Sometimes things work out the way they should. :)
