The inlet and outlet of the 27WON Performance downpipe are CAD designed for optimal flow, durability, and fitment. The market leading 3.125” downpipe inlet creates a large volume for the hot exhaust gases to escape, providing increased turbocharger efficiency and response.
Inlet and outlet flanges are manufactured from investment cast T304 stainless steel. Stainless steel piping and brackets are precision TIG welded for a long lasting and durable performance downpipe.
Precision TIG welding is utilized for the center section and the T304 SS heat shield brackets. The heat shield brackets are laser cut and formed with a multi-sided "foot" for a superior connection and durability.
