Let’s be honest—what’s the point of owning a B48-powered BMW if you can’t hear it? The factory G2X 330i/430i rear muffler assembly is oversized, heavy, and overly restrictive, muting the deep, aggressive tone that your engine was designed to produce. Our Muffler Delete System is the perfect solution for enthusiasts looking to unleash that signature turbocharged soundtrack without the cost of a full cat-back system.

Engineered and manufactured in-house, this system replaces the factory rear muffler with a free-flowing, TIG-welded 304 stainless steel setup designed to enhance tone, reduce weight, and maintain OE-level fitment and quality. At the front, 3" primary tubing mates seamlessly to your factory midpipe using a durable stainless steel sleeve clamp. At the rear axle, the primary tubing transitions to dual 3" adjustable tailpipe sections for a clean, yet aggressive look. These tailpipe sections offer compatibility with our suite of 4" exhaust tips, allowing you to tailor the system's appearance to your liking. Accuseal-style, slip-fit joints allow for easy adjustment, ensuring perfect tip placement inside the factory rear diffuser. The result? A more engaging exhaust note and a clean, motorsport-inspired appearance that transforms your BMW’s personality both visually and acoustically.

At Active Autowerke, it's not ONLY about making as much power as possible but to maximize the enjoyment of the drive. For 40 years, power has been the end result of improved performance due to our relentless desire to develop a refined, quality product. This philosophy behind our performance parts is best represented by one of the newest additions to our G2X/G3X BMW M340i and M440i collection. The Active Autowerke M340i/M440i rear exhaust was carefully engineered to eliminate the overly quiet sound of the factory M340i and M440i exhaust, while also allowing for optimum flow and resonance by reusing the actuator from the BMW valve. Every effort was made in addressing the not so appeasing sound of the stock OEM exhaust, but in designing an exhaust worthy for the BMW 'M' badge. We believe our rear exhaust offers the best combination of sound and performance versus other systems on the market today. Available for both models, this axle-back exhaust gives your BMW the deep, throaty, growl a car of its caliber should have had from the factory! Features: Made in the USA 304 Stainless Steel Low, Deep Sound with stock Valve Control Each exhaust test-fit on the M340i/M440i Exhaust Fixture Guaranteed to fit all G-series M340i and M440i Includes all necessary installation hardware

FITMENT NOTE: For G-Chassis models (G20, G22), the cutoff build date of 08/2020 is important as cars produced after that date have a downpipe with different bracket locations. Cars with a build date of 08/2020 and earlier have the brackets in a V configuration and will need Active Autowerke p/n 11-065. Cars with a build date of 09/2020 and later have the brackets in a straight line and require Active Autowerke p/n 11-065G. If your car was built in the cutover months 08/2020 and 09/2020, please call in or email us your VIN so we can ensure you get the correct downpipe.

Want to install a downpipe on your B58 equipped BMW, but still need to pass emissions? Evolution Racewerks has the answer for you with their B58 Catted downpipe. The Evolution Racewerks Competition Series Catless Downpipes is constructed from 304 stainless steel, featuring mandrel bent piping.  These are 100% TIG welded by in house fabricators and built in the USA! 

The factory turbocharger turbine housing utilizes a V-Band flange which has been duplicated and CNC machined cut out of billet 304 stainless steel. Stainless Steel CNC machined O2 sensor and laser cut brackets are TIG welded using stainless steel rods. The O2 sensor remains positioned at the factory location. Also, since Evolution Racewerks uses a larger 4.5" pipe right after the turbocharger, turbo backpressure is significantly reduced, resulting in less exhaust turbulence and backpressure which again improves throttle response and decreasing turbo lag.

The Dinan G20 330i / G22 430i exhaust grants the B46/B48 4-cylinder improved exhaust flow by reducing back pressure, and also creates a deeper and fuller note, without any added drone or other negative side effects.. The goal of OEM+ and then some. Utilizing factory cut points and mounting mechanics this Dinan exhaust system is a straightforward install with fitment like you would expect from the manufacturer. Going from the plebeian stock dual slash cut 90mm (3.5") tips to the massive Dinan straight cut 102mm (4") ones leaves no doubt that something above and beyond is present. This is solidified by the Dinan logo laser engraved on the tips and the deep growl of the exhaust that is indisputably different than anything one would expect to hear from a base 4-cylinder turbo platform. For those that wish to have options to limit the soundtrack for late night or early morning arrivals/departures, factory valve control is retained. No matter the situation the Dinan valved axle back exhaust system is the answer for the discerning enthusiast looking for performance without sacrifice. Max HP Gain4 @ 6600 RPM - Max Torque (lb-ft) Gain3 @ 6600 RPM Features: Enjoyably louder, sportier sound Drone abatement technologies used to reduce cabin resonance Dual 4" (102mm) double-walled, black ceramic coated clamp-on tips with laser engraved Dinan logo Larger diameter piping for increased flow (85mm to dual 60mm vs. 85mm to dual 83mm) 100% 304 Stainless Steel construction Retains factory valve control Factory-like fitment with included mounting hardware
