Active Autowerke BMW B46 Catted Downpipe

BMW introduced a new valve-tronic, single turbo version of its direct-injection engine for the later F-Chassis models beginning in 2016 and continuing into the G-chassis models. The Active Autowerke B46 downpipe for the 230i, 330i and 430 helps unleash some of the potential that is restricted by the OEM downpipe.

NOTE: the cutoff build date of 08/2020 is important as cars produced after that date have a downpipe with different bracket locations. Cars with build date of 08/2020 and earlier have the brackets in a V configuration and should order the F-series downpipe while cars with a build date of 09/2020 and later have the brackets in a straight line. 

If your car was built in the cutover months 08/2020 and 09/2020, please include your VIN in the order so we can ensure you get the correct downpipe.

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 B46 is quite restrictive, which results in slower exhaust gases and slower turbo spool.    

The Active Autowerke F-Chassis B46 Signature down pipe utilizes 3-1/2 inch diameter stainless steel piping in order to provide more power, quicker spool, and extreme durability. We've incorporated a stainless flex joint and then to the ball flare to meet the OEM exhaust system.

This variant includes a 4" high flow GESI catalytic converter that will NOT produce a CEL!

The GESi G-Sport High Output Catalytic Converter features full 304 stainless steel construction, including the substrate. GESi HO-Series Gen 2 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 HO-Series Catalytic Converters are rated for engines putting out between 300 and 500 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!

Please Note: These catalytic converters are not legal for use on vehicles registered in the state of California as a result of California Vehicle Code Section 27156 and 38391.

Features:

  • NO CEL for catalytic efficiency when using this downpipe

  • GESI EPA registered high flow and fully OBD2 compliant

  • Casted upper stainless steel V-Band for precise fitment

  • 3-1/2 inch diameter piping allows for maximum power output

  • Quicker turbo spool

  • Ultra high flow 400 cell per square inch catalyst

  • EPA compliant for use on OBD2 vehicles (1996 and newer) except in California

  • 304 stainless steel substrate in catalytic converter is furnace braised to the mantle for outstanding durability

  • GESi proprietary precious metal loading technology ensures greatly reduced emissions

  • Both passengers and drivers are safe from harmful emissions and noise

  • Precise fitment

  • Made in Miami, Florida

  • Covered by 5 Year / 50,000 Mile Warranty (on shell and tube ends) and 2 year / 25,000 Mile Warranty on the Catalytic core


NOTE: Federal law prohibits the tampering of an emissions control device. Mobile Source Enforcement Memorandum 1A, allows for aftermarket parts to be used in the repair or replacement of emissions control systems, provided the emissions aren't adversely affected. There is no mention or reference to cell density or converter volume dimension. The GESI catalytic converter will produce emissions that will meet the standards set by the EPA, not CARB.


Active Autowerke B46 Downpipe Benefits

The speed of a turbo's impeller wheel is limited by exhaust back pressure. A larger down pipe relieves some of this pressure, resulting in quicker and more efficient spool. With Active Autowerkeu's downpipe, your B46 can rev quicker, and deliver more horsepower and torque.

Minimizing back pressure while retaining daily drive-ability was the goal of our B46 downpipe. Owners can now upgrade to a product that is affordable, reliable, and easy to install.

After months of research and development, our engineers settled on a 3-1/2 inch diameter pipe which utilizes the least number of bends possible. The large volume helps the turbo spool as quickly as possible by eliminating back pressure during spool up. We are ushering in a new era in performance where we maintain air control standards without significant losses in power by using the GESI super high output catalytic converter in our signature downpipe.

Constructed entirely from 304 stainless steel with 1.5MM wall thickness, we are confident that you'll be pleased with how robust and durable this down pipe is. Trouble-free installation and a long lifespan ensure that you'll enjoy many miles of performance with your B46!

Chihuahua and Border Collie Approved
Flavor Name: Braided Stick (Chicken)
We got the iPaw Turkey Tendon Braided Sticks for our two senior pooches, and it’s safe to say they are an absolute hit in our household. Both of our dogs seem to genuinely love the flavor and the "chew" of these. They stayed engaged with the treat until the very last bit was gone. While they are hard, they aren't rock-hard. I was easily able to cut them up with scissors for our Chihuahua, who is missing several teeth. He was able to gum them down without any issues, which is a win for a pup with dental challenges. The only reason I’m giving these 4 stars instead of 5 is the price. They are definitely on the expensive side for the amount you get. Since my dogs go through them so quickly, it’s hard to justify keeping these as a "constant" staple in the pantry, but they make for an excellent occasional high-value treat.

Dogs loved them, but gone very quickly
Flavor Name: Braided Stick (Chicken)
I picked up these turkey tendon braided sticks as a chew treat for my dogs, and they had zero hesitation. Both dogs were immediately interested and happily worked through them without any convincing. They seem very tasty and easy for dogs to chew, which makes them a nice occasional reward. They seem to be of healthy, quality ingredients, which is always a plus. Similar to some other natural chews I’ve tried, they just don’t last very long with bigger or enthusiastic chewers. What looks like it might be a longer distraction turns into a fairly quick snack in our house. Still, the dogs enjoyed them and tolerated them well, so they work fine as a treat, just not a long lasting chew for large dogs.

Expensive for What You Get
Flavor Name: Braided Stick (Chicken), Flavor Name: Braided Stick (Chicken)
My dogs love chews and I like to try different kinds. I thought they would be longer lasting since they are braided and turkey tendon. These come in a small bag with just a few chews. The chews aren't very big either. They are chewy but not so much that they take a while to eat. I gave one to my 36 lb labradoodle and he finished it in a couple minutes - so it isn't a long-lasting treat at all. At this price point, I would expect more treats or something that lasts a while. My dog loved these but I expect more bang for my buck.

Great braided dog snacks, good ingredients - cost a bit much for the number you get
Flavor Name: Braided Stick (Chicken)
I ordered these Chicken flavored Turkey Tendon Braided Sticks for my three medium sized dogs. I had hoped these would last a little while so gave them one each (there was only like 6 in the pack), but they gobbled them down before I even realized it. They really loved them. I would love to get them these as a special treat every now and again, but they're just too expensive no longer than they last. I know that they're quality treats, made with good ingredients and that really matters, still for no more than you're getting I feel they should cost about a third less. At this rate they're about $3 a piece, and I could get more of some other treat for that price. But if you don't care about the pricing and want only the best for you dogs, then this would be a perfect choice.

Dog chew treat
Flavor Name: Braided Stick (Chicken), Flavor Name: Braided Stick (Chicken)
​I recently purchased these Turkey Tendon Braided Sticks for my dog, and they have been a huge hit. Here are a few reasons why we both liked them: ​High Engagement: My dog was immediately interested and stayed busy with the chew. ​Healthy Ingredients: I appreciate that they are a Turkey Tendon Recipe, which feels like a much healthier alternative to some other chews on the market. ​Quality Design: The braided texture seems to help with the chewing experience and likely helps keep teeth clean. ​I will definitely be buying these again. If you're looking for a treat that is both enticing and made from good ingredients, I highly recommend giving these a try!
