RMVR53 Posted June 10, 2008 Share Posted June 10, 2008 I need to "remove" the front cat on my 87 XT (non-turbo). Will an early car (say 82 GLF) fit? Need to keep the O2 but run just the mid-pipe cat Bill Link to comment Share on other sites More sharing options...
TomRhere Posted June 10, 2008 Share Posted June 10, 2008 No. The length of the tubes from where they curve up to the heads are shorter on the EA-81s. If you still have the spacer blocks that the ASV tubes attached to, then you may be able to use it. Link to comment Share on other sites More sharing options...

TomRhere Posted June 10, 2008 Share Posted June 10, 2008 Hmmm, maybe someone has swapped it over to an EA-82 Y-pipe. You can put one of those on an EA-81, but not the other way around, without the ASV spacer blocks. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted June 11, 2008 Share Posted June 11, 2008 Really old EA81's and EA71's didn't have the spacers - the ASV's injected into the top of the cylinder head. Either way, it likely won't fit an XT due to the differeces in the size/shape of the dust sheilds and clearance with the cross-member. It's also almost certainly a smaller diameter - 87 XT is 95 HP MPFI - 82 GLF is 73 HP. GD Link to comment Share on other sites More sharing options...

RMVR53 Posted June 11, 2008 Author Share Posted June 11, 2008 well, other than removing the existing pipe, cutting it back to where I can get into the cat and clean it, any other recomendations? (other than a custom made piece from a shop) Link to comment Share on other sites More sharing options...
