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.

The free flowing downpipe provides 6 wHP gains from 3200rpm to 5400rpm with no tuning changes. Both the 27WON Race-Catless and Street-Catted setups provided nearly identical power gains. Throw some custom tuning at it and the downpipe really starts to shine.
