By replacing the restrictive primary catalytic converters located in the original downpipes with specially designed high-flow sports cats, back pressure is reduced, which effectively improves the engine’s breathing by allowing it to expel gases more quickly. This in return means faster throttle response, increased power output and a more aggressive exhaust note.
Complete with replacement fitting kit, the downpipes will mate to a standard or aftermarket exhaust system and come wrapped in a heat reducing covering.
Will fit the following models:
• BMW G87 M2 (left and right-hand drive)
• BMW G80 M3 (left and right-hand drive)
• BMW G82 M4 (left and right-hand drive)
Please note:
- Sports cats are sold for motorsport and off road use only and may not pass a UK MOT test or police road side checks.
- An ECU recalibration is required in order to ensure the EML is not illuminated.
Features:
• Direct replacement part to fit both left and right-hand drive
• 200 cell sports cats reduce restriction
• Made from high quality stainless-steel
• Fits original and aftermarket exhaust systems
• AIRTEC Motorsport laser cut plaque
• Heat reducing covering included
• Comes complete with fitting kit
