Overview:

The F8x M3/M4's are an audible treat right off the showroom. Coupled with a Dinan exhaust however they become a symphony of aural delight that even the most discerning ear will find pleasing. Dinan's Free Flow axle-back exhaust system features 100% stainless steel construction measured to exact specifications to ensure proper fit via factory hangers and mounting points. Dyno tuned for maximum exhaust flow with minimum backpressure, this system is designed to provide a more aggressive sound under acceleration, while reducing drone inside the vehicle, thanks to computer-controlled valves that limit noise during low-speed driving and open fully during high-load conditions to allow free flow. The exhaust gasses exit through larger laser engraved polished, or ceramic black, quad tips. Every Dinan product comes with our industry-exclusive factory matching new car bumper to bumper warranty and is designed and tested in Morgan Hill, California and can be purchased and installed at any Dinan Approved BMW dealership nationwide.

Features:

  • More Power: +5 HP
  • Drone abatement technologies used to reduce cabin resonance
  • Enjoyably louder, sporter sound
  • Quad 3.5" black ceramic coated, or polished stainless, laser engraved exhaust tips
  • Computer controlled valve limits noise during low speed driving; valve opens fully during high-load conditions to allow free flow
  • Stock exhaust valve actuaters are reused
  • Operation of exhaust valve is unchanged so exhaust tone can be adjusted via the M-Drive settings. 
  • Dinan exhaust is 3 lbs lighter than stock
  • Twin secondary exhaust valves with a whopping 76mm diameter, making them 45% less restrictive than the OE valves.
  • 100% 304 stainless steel construction
  • Uses the factory brackets and hangers for a factory-like fitment

Works in 2019 Subaru Outback!
If you are looking for an engine air filter to fit in your 2019 Subaru Outback then look no further -this one will fit. I tried two others that would not allow me to close the compartment door with the latches. This one slipped in like a hand in a glove.

Fits 2010 Subaru Forester with 2.5 non-turbo
Definitely looks and feels like a better than OEM air filter. Not sure of any other benefits.

Good Quality, Good Price for a Subaru Replacement Air Filter
Look like a great name brand filter. Not a bad price for a Subaru (2013) replacement. I will buy again if available.
