After getting new cats fitted at a hefty cost from the dealer, they flipping things are blocked again...
My GTA is really starting to get on my nerves, just replaced cambelts, tensioner, water pump, thermostat, idlers, oil, spark plugs, intake manifold gaskets, suspension bushes,.. and now the cats are blocked and she's hobbling.
Tell me guys, if i fit the supersprint full exhaust system, what will happen re: the lamda sensors. The GTA has 2 cats on the manifolds and another cat in the exhaust later on about halfway down the under carriage.. does the supersprint header have a place to connect the lamda sensors, or can they be bypassed and the ECU fooled into taking readings from the cat in the centre of the exhaust?
