The Fabspeed Mid-Pipes are perfect for anyone who already has aftermarket headers on their M3, but are looking for an increased flow. Constructed from high quality T304 stainless steel for optimum performance and longevity. Replacing your stock secondary catalytic converters with the Fabspeed Mid-Pipe without sport cats creates gains for more midrange power, and add an aggressive sports car sound.
By adding the Fabspeed Mid-Pipes with 200-Cell Sport Cats installed, which replaces your current secondary catalytic converters with the Sport Cats, your M3 will not throw a check engine light. If you don't need the 200-Cell Sport Cats you can opt for the Cat Bypass Pipes which replace your existing secondary catalytic converters and allows for a nearly unrestricted airflow.
With the Fabspeed Mid-Pipes with Sport Cats your E46 M3 will pass emissions and inspections.Benefits
