boondockpa Posted January 7, 2012 Share Posted January 7, 2012 I know this is probably a question that has been answered a dozen times, but I searched and could find it. Will a impreza outback header and cat fit a 01 outback Ltd. I'm sorry if its already been asked. thanks Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted January 7, 2012 Share Posted January 7, 2012 Depends on the engines involved. You mostly just have to match the ports on the heads. Dual port headers will not work on a single port engine, and vice versa. Quote Link to comment Share on other sites More sharing options...
boondockpa Posted January 7, 2012 Author Share Posted January 7, 2012 both i think are dual port 01 impreza outback onto a legacy outback Ltd, should ej25s. the main thing I'm worried about is that the header are equal length, not sure if they will fit since they are routed differently. obx doesn't list it fitting the legacy outback but was hoping it would with little or no notifications. I was thinking the outback sport should be the same sub structure as the outback sport but wasn't 100%. thank you for any help Quote Link to comment Share on other sites More sharing options...
