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

  • 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

  • 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!

Honestly the best
Size: 8 Ounce (Pack of 1)
I have pretty sensitive skin and have keratosis pilaris on my arms. This is honestly the best lotion I’ve ever used and I’ve tried many many lotions. My skin is soft but not greasy. My arms feel soft which is a huge deal. I’ve been using it for months now and I don’t think I’ll ever use anything else.

Absolutely Love It – Deep Hydration That Lasts!
Size: 8 Ounce (Pack of 1)
The Dove Body Cream Serum with Hyaluronic + Hydration has quickly become my go-to for tackling extra dry, flaky skin — and I absolutely love it! 💧 Deep, Lasting Hydration: From the first use, my skin felt instantly hydrated — and what’s even better? That hydration actually lasts throughout the day. No more reapplying! 🧴 Lightweight & Non-Sticky: It goes on smoothly, absorbs quickly, and doesn’t leave that greasy or sticky feeling — just soft, nourished skin. 🌿 Skin-Loving Ingredients: With pro-ceramides, niacinamide, and collagen peptides, it feels more like a high-end skincare product than a typical lotion. My skin looks visibly healthier, more even-toned, and has a soft glow. ✨ Bonus: It’s gentle enough for daily use and has a clean, fresh scent that’s not overpowering. If you’re dealing with extra dry or flaky skin and want something that works and feels luxurious, this is it. Dove nailed it with this one — hydration, comfort, and glow in one bottle. #DoveBodyCare #HydrationThatLasts #SoftHealthySkin #DrySkinSolution #SkincareMustHave #GlowUpWithDove

Soft Skin All Day Without That Greasy Feel
Size: 8 Ounce (Pack of 1), Size: 8 Ounce (Pack of 1)
My skin is dry and tends to get ashy, and after showering it can look worse, especially on my hands, elbows, knees, and heels. I apply this while my skin is still slightly damp. It goes on creamy but absorbs quickly, so I don’t get that greasy or sticky feeling some lotions or body creams leave behind. I can get dressed right away without waiting. It keeps my skin looking and feeling hydrated all day without needing to reapply. The scent is light and clean, nothing strong or overpowering. If your skin is severely dry or cracked, you may need something thicker. For my dryness, this does the job. It’s the one bottle I reach for every day.

Disliked at first, ended up LOVING!
Size: 8 Ounce (Pack of 1)
UPDATE: I actually ended up loving this product once I started treating it as a first layer serum. I use a very small amount, let it soak in for a minute or two, and then layer a body lotion over it. Using it that way gives me the softest skim (even on rough dry areas like elbows) and it totally takes away any sticky/tacky feeling! I don’t quite know how to feel about this product. It is hands down one of the most hydrating body lotions around and immediately after application skin does feel silky and smooth. It causes no irritation and has almost no scent. However the longer it is on the more tacky and sticky it gets- even dabbing extra off with a towel does not help. It is particularly bad on the hands, I literally could not stand it because it felt like I had partially dried glue all over my hands. Strangely the one place this lotion works on is my feet and it really helps with any dryness (I’m an avid walker and hiker so my feet get dry). I would not purchase again because I can’t use it anywhere else. I wish it stayed feeling like it does immediately after application because I bet it would help skin look and feel smoother with continued use, but unless the formula changes to something that isn’t tacky and sticky it is basically worthless. Unless you want to purchase as a foot cream!
