The NRP Signature Valved Exhaust System for the BMW G30 540i replaces the factory exhaust from the downpipe back with a full valved catback. The B58 is one of the best-sounding inline-sixes BMW has built, and the 540i's stock exhaust was tuned for silence. With the valves open you get a clean, deep six-cylinder note with crackles on overrun; closed, the car stays as quiet as it came. Direct bolt-on using the factory mounting points, and 100% reversible.
Features:
- Full valved catback — replaces the factory system from the downpipe back
- Electronic exhaust valves — quiet with the valves closed, full volume open
- Mandrel-bent, TIG-welded construction for maximum flow
- Works with the OEM downpipe or any aftermarket downpipe built for it

- NRP Lifetime Warranty
