| HKS Subaru 02-07 WRX & 04-07 STi Downpipe |
|
 |
| The HKS WRX & STi Downpipe is designed as a simple, cheap solution for making power. The HKS WRX downpipe will eliminate both catalytic converters on your 2002-2007 Subaru WRX or 2004-2007 STi, and features 3" piping for optimal flow.
While the HKS downpipe will improve performance, we do not reccomend it for anything other than a stock turbo, due to the flat-plate design that does creates wastegate turbulence. Because the HKS downpipe eliminates both catalytic converters, it is not emissions legal and will
trigger an emissions Check Engine Light (CEL) -- while it is not harmful, we reccomend the Cobb Accessport to properly tune the vehicle for the downpipe and eliminate the CEL. The HKS WRX & STi downpipe does help reduce boost spiking in 2.5L Subaru cars because of the reduced wastegate flow. This
downpipe is full 3" with a flat rear flange, so we recommend an aftermarket 3" catback exhaust for proper fitment. |
