Description
Unlock the full potential of your BMW M2, M240i, 340i, 440i, 540i, or 740i with our high-performance Catted Downpipe with Heat Shield. Designed for models with B58 engines, this downpipe features a 4.5" input flange and a 4" mandrel-bent tubing constructed from 304 stainless steel, TIG-welded to ensure durability and a brushed finish for a sleek look. The straight-through design eliminates the restrictive OEM catalytic converters, enhancing horsepower and torque—approximately 25 HP with a tune. The integrated heat shield directs exhaust heat away from critical components, reducing surface temperatures by up to 70% and minimizing turbo lag. Ideal for track and high-performance applications, this downpipe is a direct bolt-on replacement for OEM components.
Key Features:
- High-Performance Design: Straight-through tubing maximizes power and sound by replacing restrictive OEM catalytic converters.
- Durable Construction: Made from 304 stainless steel, TIG-welded for strength, with a brushed finish.
- Heat Shield Included: Protects surrounding parts, wires, and hoses from radiant heat with integrated thermal insulation that reduces surface temperature by up to 70%.
- Enhanced Performance: Improves horsepower and torque by approximately 25 HP with a tune. Reduces turbo lag and thermal load on the turbocharger.
- Flex Joint: Reduces engine vibration and allows for proper alignment during installation.
- Direct Replacement: Easy bolt-on installation for left-hand drive models, replacing OEM primary catalytic converters.
