Having problems with your 1999 Isuzu Trooper ?
How many Catalyic Converter on my Trooper? I was told 2 one on the right side and one on the left side. Also how do you know when they are going bad.
You should have 2, these will either send you a code, or sometimes the baffles inside will break loose and rattle. The biggest problem, if these get clogged or stopped up this will cause back pressure to your engine and cause more damage than you would think. It's more less to check the function of them, you can have a emission test done. Aftermarket converters are fine which are about $350 but OEM are around $1000
