MagnaFlow SYS C/B 08-09 BMW 128i 3.0L

Magnaflow is well-known for making exhaust systems that sound great and perform even better. This Touring Series cat-back system is a perfect match for your 2008-2013 BMW 128i, whether you're heading out on a long trip or just enjoying a weekend drive. It's designed to give your 3.0L engine a powerful, resonant exhaust note that's noticeable without being overwhelming, and it's dyno-proven to increase horsepower and torque.

This system is built to last, using durable, corrosion-resistant 409 stainless steel. The main piping is 2.5 inches in diameter and features mandrel bends, which means the pipe's diameter stays consistent throughout the bend. This allows exhaust gases to flow more freely compared to stock systems, contributing to that performance increase. It exits on the driver's side rear with dual 3.5-inch polished, double-wall angle-cut tips. The system replaces your stock exhaust from the catalytic converter back, and Magnaflow used extensive 3D scans during development to ensure a direct-fit design that installs easily.

This cat-back system is designed for moderate exterior sound and mild interior sound levels. It's produced using CNC precision robotic manufacturing and comes with Magnaflow's limited lifetime construction warranty, giving you confidence in its build quality for years to come.
