Complete your Raptor R headers with the connections that fit
Join your Kooks long tube headers to the OEM rear exhaust with these stainless Raptor R connection pipes. Choose Competition Only, GREEN, H.O. GREEN or Ultra-GREEN catalysts, each with a 3" front connection and 3-1/2" factory-style rear outlet.
SKUs: 13723100, 13723300, 13723400, 13723500
Four choices for the front pipework
Competition Only is the uncatted choice for competition use. The three catted options let you select the catalyst specification around your supercharged build. All four require Kooks headers and include the installation hardware.
Retain the factory rear interface
The 3-1/2" rear outlet keeps the OEM exhaust connection available. For the GREEN, H.O. GREEN and Ultra-GREEN pipes, Kooks also recommends 9003A O2 spacers. Plan the sensor arrangement with your installer and tuner as part of the completed system.
