OK so theres 2 cats on the downpipes from the exhaust manifolds then a third cat where the pipes meet(out of the first 2 cats) and then the silencer right????i had two 40 series mufflers put on and 2 1/2 inch pipe from the tird cat back.. sound is too quiet .... ideas? im thinking of removing the third cat but will this cause a error code? check engine light etc? maybe a clogged cat? also the car kinda stumbles at idle and i just put new wires, plugs, coil packs in.
anyone have a sound clip of their flowmaster 40 series mark?
thanks........
