wcbjr Posted January 30, 2007 Share Posted January 30, 2007 How in the world are downpipes more expensive than exhaust manifolds? Particularly the BPM manifold. I forgot what I was supposed to remember. Link to comment Share on other sites More sharing options...
rc0032 Posted January 30, 2007 Share Posted January 30, 2007 Quantity More exhaust manifolds are built than DP's Link to comment Share on other sites More sharing options...
praedet Posted January 30, 2007 Share Posted January 30, 2007 The BPM is just a cross-pipe, not the full manifold. You use your stock elbows with their cross-pipe... Ted Link to comment Share on other sites More sharing options...
wcbjr Posted January 30, 2007 Author Share Posted January 30, 2007 Forgot about that. But still. When is the ERZ going to come into view, I wonder... I forgot what I was supposed to remember. Link to comment Share on other sites More sharing options...
jim1969 Posted January 30, 2007 Share Posted January 30, 2007 because we share the same manifold and up-pipe as the WRX/STI/FXT but our downpipe/midpipe/CBE are different. So there's a lot more manifolds available but only legacy specific stuff from the turbo back. Link to comment Share on other sites More sharing options...
