Forgive the lack of technical knowledge but here goes. Recently been getting a rattle when putting the power down at low revs, usually about 2k, at first I thought it was the manifold bracket as normal but everything seems okay. Took it to my local exhaust guys and turns out one of the cats has gone, there's ceramic in the exhaust ratlling around. Now for the question, there are 2 cats?? at the front then there is a section which has 2 boxes in it (the faulty cat so i'm told), then there is the nice rusty pipe section leading to my back box, can I make do without the section with the 2 boxes or does that count as decat and bang goes my MOT.
If not then i'm in need of that section of pipe with the 2 box bits (aren't I technical) so does anyone know how much a complete system like that should cost, garage quoted 670!!!! at me, if I can do without the box section that would be great and I could just get a custom pipe made up but my gut tells me that will fail an MOT.
Exhausts aren't my thing as you can probably tell
, also if anyone has that section and don't need it then I would gladly take it off your hands.
670 GBP is excessive, here you can get them much cheaper for about 350 - 400. Fitting is just a few bolts:
It should be even cheaper from a breaker.
You can live without the 2 "boxes" (pre-cats) and you will not fail the MOT as the main cat that is under the car and you cant see it will be enough. Precat funcion is to keep the emisions down only in the first moments after startup till the main cat is not hot enough.
Buying downpipes without precats or complete manifold is the same money (or much more) than geting original ones. You can get some more power with this as well...
I would go the breaker option....
