Probably a dumb ?, but I figured I ask first before I tear my 06 STI apart & find out Im screwed. The manuals w/the TBE say 2002+ WRX/STI. The Cobb site says 04-06 STI for TBE & DP. The Cat DP is #512202 & the CBE is 512100. I checked the Cobb site and they showed no part #s. Anyone run into this & know whats up. Did Cobb just not update the manuals or do I have the wrong set-up? If anyone knows plz post, I don't want to tear apart my car & find out then. BTW are you guys pulling out the TMIC for the DP install or getting it done w/it in place?
