Description

Dinan Free Flow Axle-Back Exhaust - 2020-2024 BMW M340i/M440i

Quad exhaust tips have been a signature feature of the most powerful letter in the automotive sphere for quite some time. It is a hallmark of the brand that Dinan has long embraced, limiting its own quad tip usage to those M cars that already sported like tip quantity from the factory. That is? until now with the release of the Dinan axle back exhaust system for the G20 M340i and G2x M440i.

Features:

  • More Power: +?6 HP @ 6600 RPM, + 5 LB-FT @ 6600 RPM
  • Enjoyably louder, sportier sound
  • Quad 4" diameter clamp-on, double-walled, polished and laser engraved exhaust tips
  • 100% 304 stainless steel construction
  • Larger diameter piping for increased flow (76mm vs 70mm)
  • 4 lbs lighter than the stock system
  • Stock exhaust valve actuator reused and another valve/actuator added to the opposing side promoting even flow regardless of valve position
  • Computer controlled exhaust valves are retained and limit noise during low speed driving and open fully during high-load conditions
  • Twin exhaust valves are a whopping 76mm diameter, making them 30% less restrictive than the OE valves
  • Easy bolt-on installation with included mounting hardware
