AR Design 4" Hi-Flo Downpipes With 5" Race Cats - F06/12/13 F10 N55 Engine

Narrow exhaust pipes can be a major restriction to performance. If you are looking for top of the line downpipes, AR Design has you covered with their Hi-Flo Downpipes. These are perfect to add power, performance, and stunningly good looks. Made 100% in the United States of 3" 304 stainless steel tubing and expertly welded with some of the best looking welds on the market, the guys at AR Design are so confident in their material and build quality, they give you a lifetime warranty against manufacturing defects and a three year warranty against rust and corrosion.

These performance downpipes produce more power than the stock exhaust pipes and add a sporty exotic tone to your exhaust note. These downpipes also include a Race Catalytic Converter to ensure both high flow and emissions compliance for cars driven on the street in addition to the track.

These are available as stainless or with a ceramic coating rated up to 2000 degrees Fahrenheit. This helps keep the heat from radiating into the engine bay, keeping air intake temperatures much lower! Two coating options are available: Silver and Black.

Included in this kit:

  • 3" Downpipes
  • Race Cats
  • "Bomb-Proof" exhaust gaskets
  • Grade 10.9 metric hardware for high durability
