Dinan D660-4604 Free Flow Axle-Back Exhaust for BMW E46 M3 — Overview
This is Dinan's axle-back exhaust for the E46 M3, built specifically around the S54 straight-six. It replaces the section from the rear axle back, so you're keeping your stock mid-pipe and catalytic converters in place - good news if you're staying emissions-legal or just want a bolt-on weekend upgrade without touching the whole underside of the car. Dinan engineered this to flow better than the factory unit while keeping the tone tasteful rather than obnoxious, which is the right call for a car you might actually daily.
