iwanprice12 Posted April 16, 2015 Share Posted April 16, 2015 (edited) The Zed went for an MOT today with a couple of advisories, Front tyres worn on the inside, Rubbefrsuspension bush deteriorated but not excessive. Another advisory was that the front exhaust system has deteriorated. Having looked underneath the car & not having a chance to talk to the MOT tester, it seems there are some 'holes' to the casing of the Cats. Been doing some research to get some new CATS (money is tight this month), but it seems the OEM CATS seem to be more expensive (used) than sports/high flow CATS. Can anybody shed some light on why this is? When ££ allows, was thinking of changing from the 'Y' pipe back with a Cobra resonated system, but seems this will have to wait now. What would be thegoing rate on OEM ones compared to High flo? Don't want DECATS tbh.

a2orry Posted April 16, 2015 Share Posted April 16, 2015 Sounds like the heat shields on the cats .possible that the flexible joints are on ther way out. Quote Link to comment Share on other sites More sharing options...
KyleR Posted April 16, 2015 Share Posted April 16, 2015 a2orry appears to be correct, it'll be the heat shields. So just ignore the advisory and buy the Cobra 1 Quote Link to comment Share on other sites More sharing options...

KyleR Posted April 17, 2015 Share Posted April 17, 2015 If it was the actual shell of the cats you'd hear it. The car would sound like @*!#! lol Quote Link to comment Share on other sites More sharing options...
BulletMagnet Posted April 18, 2015 Share Posted April 18, 2015 The heatshields on my cats had deteriorated so bad they came loose and rattled. Local garage (UK) removed them for me 1 Quote Link to comment Share on other sites More sharing options...
