MagnaFlow SYS C/B 01-05 BMW 330I/CI 3.0L

With this MagnaFlow Touring Series cat-back exhaust system, you get the main exhaust piping, two straight-through mufflers, and the dual rear exit tips. It's designed to replace your stock exhaust from the catalytic converter back, giving your 2001-2006 BMW 330Ci or 330i a more resonant sound and improved performance.

This system is built from 409 stainless steel, which helps it resist corrosion and stand up to the miles. The main piping is 2.5 inches in diameter and is mandrel bent, meaning it maintains its shape throughout the bend for better exhaust flow compared to crush-bent tubing. This design, along with the straight-through mufflers, contributes to dyno-proven performance gains in horsepower and torque. You'll notice a moderate exterior sound level and a mild interior sound, making it suitable for longer drives or daily use. The system exits in a dual configuration on the rear driver's side, featuring 3-inch polished double-wall angle-cut rolled edge tips.

MagnaFlow used extensive 3D scans during development to ensure this system offers a direct-fit installation that works with your BMW's factory mounting points. It's produced using CNC precision robotic manufacturing techniques and comes with MagnaFlow's limited lifetime construction warranty, giving you confidence in its build.
