Title: 3.2 exhaust question
Post by: 0795omega on 05 July 2012, 22:00:37

my omega is going back in fri for its mot work one thing is the need for an exhaust system,but have one from my power sounder destroyed 2.5 which ive been told on here will fit,he says i could do with cats aswell personally i think he doesnt fancy separating them,in my opinion the cats are a1 just rusty on there outer skin,was told even by an exhaust place when having tracking done they were fine! plus looking at prices of them they are ruiningly expensive! so hoping all goes well the 3.2 cats separate o.k. and all maries upto the 2.5 system which i see has gm centre boxes and a bosal back box+ set me back £450.00 a year or so ago.

Centre box back is the same IIRC, but the CAT section is definitely different - 2.5/3.0 has no precat, different flange and different O2 sensor setup; there's a thread here recently of the modifications required to make the earlier parts fit the later car.

don't mess around changing the cats when it's just a 'zorst problem.  that'll create even more work and problems
