Special note: Factory computer-controlled exhaust valve is eliminated.
Unlock the sound and performance your BMW G30 540i deserves with the Dinan Free Flow Stainless Axle-Back Exhaust with black tips. Designed for the B58-powered 540i, this performance exhaust reduces back pressure for improved exhaust flow, delivering increased power and a deep, sporty tone that stays civilised on the cruise and turns pleasantly aggressive under hard acceleration. Expect sharper response, intoxicating burbles and pops, and a premium finish that looks as good as it sounds.
Inside the cabin the experience remains refined thanks to an integrated Helmholtz chamber that cuts low-RPM resonance to help reduce drone. Outside, the note is purposeful and performance-led. This is exactly how a BMW 5 Series 540i should sound.
Engineered to exacting standards, the Dinan G30 540i exhaust is built from 100% 16 gauge 304 stainless steel for long-term durability and corrosion resistance. It fits perfectly on factory hangers for a precise, rattle-free installation and comes complete with mounting hardware for a straightforward bolt-on upgrade. The show-stopping finishing touch is a pair of massive quadrilateral black ceramic coated tips, each laser engraved with the Dinan logo. With over 8" of width and 4" of height per tip, the rear of the 540i takes on a more aggressive, motorsport-inspired stance that matches the tonal makeover.
We have fitted and run this system ourselves and our customers consistently praise the sound quality, fitment and finish. If you want the best BMW G30 540i axle-back exhaust for everyday drivability and weekend excitement, this Dinan system is a top choice.
