MagnaFlow Sys C/B 01-05 BMW 3-series 2.5/3.0L

If you're looking to give your 2001-2005 BMW 325Ci or 325i a more engaging sound and a bit more pep, this MagnaFlow Touring Series cat-back exhaust system is a solid choice. It replaces your stock system from the catalytic converter back, aiming to improve exhaust flow for a better driving experience on long trips or weekend drives.

This system is constructed from 409 stainless steel, which helps resist corrosion and keep it looking good mile after mile. The tubing is mandrel bent to a 2.5-inch diameter, allowing exhaust gases to move more freely than a stock setup. Inside, a straight-through muffler design contributes to a moderate exterior sound level and a mild interior tone, so it sounds sportier without being overwhelming. The system exits on the driver's side rear with 3-inch polished double-wall tips.

MagnaFlow uses extensive 3D scans to ensure a direct-fit installation, meaning it should bolt up to your BMW without major modifications. The system is produced using CNC precision robotic manufacturing and comes with MagnaFlow's limited lifetime warranty on construction.
