These Supersprint sport catalytic converters are designed to be used with their Race cat-less downpipes. These are metallic sport HJS catalytic converters that are some of the best sport cats on the market. Using these with the M3/M4 cat-less downpipes will produce more power over the stock system with less heat and less complication but will require special software, modules, or a stand-alone engine management to keep the check engine light and fault codes from appearing. Straight pipes with no cats are also available for full-race systems where no cats are required. These front cats are designed to be used only with the Supersprint section 2 H-pipe. Supersprint/HJS sport cats, combined with cat-less downpipes, are the best way for producing power and still cleansing the exhaust gas.

Active Autowerke’s Aflow Catted Downpipe offers the perfect balance for the BMW owner who demands high performance but requires daily-driver refinement. Unlike track-only "straight pipes," the Aflow system utilizes a sophisticated metallic substrate catalytic converter that significantly reduces harmful emissions and raw fuel odors. This allows you to enjoy the power of a high-flow exhaust while maintaining a clean cabin environment and remaining OBD2 compliant. Each unit is custom-made in Miami and features cast upper flanges to ensure a factory-perfect, leak-free seal every time. Key Features: Clean Performance: High-flow catalyst virtually eliminates the raw fuel smell associated with aftermarket downpipes. Precision Engineering: Features a casted stainless steel upper V-band for a surgical fit against the turbo housing. OBD2 Compliance: Engineered to satisfy factory emissions monitors, keeping the dash clear of "Efficiency" codes. Refined Acoustics: Increases the exhaust volume under wide-open throttle while remaining quiet and sophisticated during highway cruising. Heat Management: Designed to withstand the intense thermal cycles of a high-output turbocharged engine. Specifications: Catalyst Cell Density: Optimized for high-flow performance and emissions scrubbing Fabrication: Hand-made in Miami, Florida, USA Inlet Type: Casted Stainless Steel V-Band Weight: Significantly lighter than the heavy factory ceramic catalytic converter Vehicle Fitment: * 2014–2016 BMW M235i (F22) 2012–2015 BMW 335i (F30/F31/F34) 2014–2016 BMW 435i (F32/F33/F36) 2016–2018 BMW M2 (F87 - N55 Engine Only)

Get that aggressive tone fitting for the M3 and M4! The Dinan High Flow X-pipe for the F80/F82 M3/M4 elicits an aggressive sound that is sure to capture the ear of all bystanders and delivers the aural recognition that all M3/M4 owners deserve. Coupled with the associated Dinan exhaust the sound is further perfected into an aggressive growl that harkens back to the Dinan E9x M3 racing middle exhaust. Rightly so, as the same custom 'X' that was used in that application is implemented on the new F8x chassis for that perfect mix of exotic undertones and raw aggression. Unlike a stamped x-pipe that is so common in the marketplace the Dinan 'X' is thoughtfully designed for maximum flow characteristics and by itself is a work of art. The Dinan X-Pipe removes the factory center section after the secondary catalytic converters, including the large resonator. In its place Dinan introduces straight through mandrel bent 2.75" T304 stainless steel tubing and the custom 'X' for better flow, and an improved throaty sound. In addition, the kit comes complete with mounting hardware, OE quality clamps, and flanges, for simplified installation. NOTE: Since a resonator is deleted there is potential for increased cabin noise associated with the Dinan High Flow X-Pipe. Features: Deletes both resonators, between catalyst and rear muffler. Stock hydro-formed 65mm tubing is replaced by 2.75" (70mm) mandrel-bent tubing for free flow. Includes X-pipe crossover made from mandrel bent tubing for minimum restriction, unlike stamped X-pipes 100% 304 stainless steel construction. Bolt-on installation. Includes mounting hardware.
