Unlock Your Turbocharged BMW’s True Potential

Introducing our Sports Series 4" High Flow Metallic Catted Downpipe, engineered specifically for the U.S.-spec B46 or B48 2.0L turbo engine. Note: This is not compatible with B48 engines found in EU/Asia models—the downpipes are not interchangeable due to design differences.

Why Upgrade?

Factory downpipes include a restrictive ceramic catalytic converter with a 900-cell core, significantly choking exhaust flow and creating turbulence, especially harmful in turbocharged applications. Exhaust gases must squeeze through these fine "honeycomb" structures, slowing velocity and increasing backpressure.

Our solution: a 200-cell metallic core that provides vastly better flow characteristics. Fewer cells per square inch = larger internal flow paths = better breathing for your turbo.

Benefits include:

Increased horsepower and torque
Faster turbo spool-up and reduced lag
Sharper throttle response
Cooler operating temps and improved durability

Performance Gains (Based on Dyno Testing)

+9 to 11 WHP (varies based on mods)
+15 WTQ average (stock ECU)
+20+ WTQ with software tuning
Broader, higher torque curve
Power comes on earlier and lasts longer across RPM range

Premium Build Quality

Every downpipe is crafted in-house using the highest quality materials and techniques for durability and reliability on both street and track.

Key Construction Features:

Mandrel-bent 4" piping for optimal exhaust flow
100% 304 stainless steel for corrosion resistance
100% TIG welded by skilled fabricators
CNC-machined 4" V-band turbo flange from billet
CNC-machined ball joint flange with a true-flow internal design
Laser-cut stainless steel mounting brackets

Smarter Transition Design

The factory downpipe reduces pipe diameter too quickly (4" to 3"), creating turbulence at both ends of the cat. Our design incorporates longer, smoother transitions from the turbo to the exhaust, resulting in less flow disruption, better throttle response, and faster turbo spool-up.

Flex Section for Real-World Durability

We retain the factory-style stainless steel flex bellow, allowing critical movement and flexibility in your exhaust system. This prevents stress cracks and premature failure—especially important for lowered cars or vehicles subjected to rough roads or aggressive driving.

Cheap aftermarket flex joints often only use stainless braid with mild steel end caps—ours are 100% stainless steel, inside and out.

Available Options

Mirror polish or brushed finish
High-temp black thermal coating (reduces underhood temps)
Additional O2 bung (for wideband sensors, includes plug)
Optional EGT sensor port (includes pre-installed plug)

Compatibility & Installation

Direct bolt-on fit for factory or aftermarket exhaust systems
Includes all necessary hardware for installation
Track-tested durability
Limited Lifetime Warranty
Proudly made in the USA

***On xDrive / all wheel drive models, there is a driveshalf running from the transfer case to the rear differential that the standard front wheel drive cars do not have. This driveshaft sits right underneath the downpipe and blocks the removal. On a typical installation, you would need to disconnect the driveshaft (requires special driveshaft tool) or lower the front subframe to give enough clearance to remove the downpipe. This add significant installation time and complication to the installation. Our solution is the 2 piece xDrive version allows you to remove and install the downpipe without removing the driveshaft or lowering the front subframe. This will save you considerable time (money) on installation and allows quicker, easier servicing.***

Testimonials

Had my 21 JCW DME cloned and tuned by Abel. excellent support throughout the entire process from beginning to completion. The car drives well with linear torque in every gear! Sure beats femto unlock.

Fred

Abel was quick to help me out and answer my questions via Email. I made an appointment with Abel to unlock and tune my 23 S. He showed up happy to help, and we got it knocked out in a few hours. It was a night and day difference, and I highly recommend this company to all mini Gen3 owners.

Modded Mini developed new upgrades for our 2021 Mini GP3 race cars. At the first race of the season, we experienced some technical difficulties related to fuel. Abel was able to figure out and fix the issue in no time “ 20 min “ over the computer at the track. He knows we will be racing over the weekend, and his dedication and standing behind his product speak for themselves. Our team achieved P1 and P2!
