BMW G20 M340i M440i Full Modular Catback Exhaust | IRL

The IRL Full Modular Catback is the ultimate exhaust upgrade for the BMW M340i and M440i. Building on the IRL Modular Midpipe, it maximizes flow with a true single layout.

Why you need it

It balances power, sound and precision without sacrificing drivability, with a 13-25% increase in flow depending on your downpipe setup.
