Axleback exhaust systems generally include what's behind your rear axle. These are among the easiest of exhaust upgrades to install, and give you an instant upgrade in sound.
True BMW performance, durability, and attractive weight advantages with innovative features place the Active Autowerke BMW F3x 335i exhaust in a class of its own. And now Active Autowerke has developed Gen 2 of this model which has been enhanced to take advantage of the OEM valve system. This system is constructed from 100% Brushed 304-stainless steel and features adjustable brushed Active Autowerke double-walled tips. And now the improved sound becomes more pronounced when the valve is opened by the ECU. Rather than creating a complete exhaust system, Active Autowerke opted for a compact design built in a smaller package to deliver more value. The Active Autowerke F3x 335i Gen 2 BMW Rear Exhaust System provides an increase in horsepower, better sound and appearance making it the choice for the avid BMW enthusiast. The system is a straight-through design providing substantial improvements to gas flow over the factory exhaust. Our innovative muffler can design provides maximum volume with the exhaust valve open for a true sport sound. This exhaust delivers a wide-open sound, a solid 15+hp boost and key gains in the midrange with the valve open while the sound comes out nonintrusive with a rich mellow tone with the valve closed. Just like replacing the BMW factory rear exhaust, the Active Autowerke BMW Performance rear exhaust does it in much the same way, if not better by using a much beefier, heavy-duty TORCA style exhaust clamp. TORCA clamps are known for their strength and sealing capabilities to make that tight seal. Other features like height-adjustable mounting tabs make this exhaust easy to install. Key Features: Large mandrel bent piping for maximum flow Uses factory valve system for maximum exhaust sound Durable, Brushed 100% 304 stainless steel for durability Double-walled signature brushed, black or carbon stainless tips Adjustable Tips with Embossed Active Autowerke Logo Improved power & torque throughout entire RPM band Gains of 12-15 HP over stock configuration Tight seal with use of TORCA style exhaust clamps Height adjustable mounting brackets make installation easy Factory curb weight 27.0 Lbs, Active 335i weighs 22.0 Lbs Fitment for Coupe, Convertible and Sedans Complete illustrated instruction manual Two-year warranty Applications: BMW F30 335i, xi (Sedan) BMW F32 435i, xi (Coupe) BMW F33 435i, xi (Convertible) BMW F36 435i (Coupe)

Dial In B58 Sound and Performance — the Turner Way Looking for a noticeable bump in sound and flow without replacing the entire exhaust system? The Active Autowerke Gen 2 Rear Exhaust for B58-powered BMW models delivers meaningful gains in a clean, well-engineered package. This rear section focuses on improving exhaust efficiency and tone while maintaining the refinement and daily usability expected from a properly sorted BMW. At the heart of the system is a straight-through muffler design that reduces backpressure versus the restrictive factory unit. The result is improved horsepower and torque, particularly through the midrange where the B58 responds best. With the factory valve open, the exhaust produces a more aggressive sport tone. Close the valve and the sound remains controlled and comfortable for everyday driving. Construction is centered on durability and proper fit. Large mandrel-bent tubing and a brushed 304 stainless steel body provide long-term corrosion resistance and consistent flow. Double-walled signature tips — available in brushed, black, or carbon stainless — finish the rear with a clean, purposeful appearance. Installation is straightforward thanks to height-adjustable mounting brackets and the inclusion of a heavy-duty TORCA-style clamp, known for its strong sealing capability and secure fitment. Independent testing shows gains of approximately 12–15 horsepower over stock while reducing overall weight compared to the factory rear exhaust. Product Highlights Straight-through muffler design for improved exhaust flow Retains factory exhaust valve functionality Large mandrel-bent piping supports increased performance Constructed from 100% brushed 304 stainless steel Double-walled tips available in brushed, black, or carbon finishes Adjustable tips with embossed Active Autowerke branding Noticeable horsepower and torque improvements across the RPM range Approximate gains of 12–15 HP over stock TORCA-style clamp provides a secure, leak-resistant connection Height-adjustable mounting brackets ease installation Weight reduction versus factory exhaust (22.0 lbs vs. 27.0 lbs) Includes illustrated installation instructions Covered by a two-year warranty Fitment BMW F30 340i / 340i xDrive (Sedan) — 2013+ BMW F32 440i / 440i xDrive (Coupe) — 2013+ BMW F33 440i / 440i xDrive (Convertible) — 2013+ A well-balanced upgrade for enthusiasts who want stronger sound, measurable performance gains, and OEM-like fit and function without unnecessary complexity.
