Having problems with your 2000 Chevrolet Silverado 1500 ?
Got a 0300 code and a 0405 code. Is there a way to straight pipe these converters?
Yes you can remove them and it will run fine but you will never get rid of the check engine lamp. You have o2 sensors behind the converters that monitor their efficiency. Jegs sells a o2 simulator that can plug in in place of the rear sensors that seems to work. The other alternative is to have aftermarket converters welded on. As for the 300 random misfire code you need to diagnose the cause of the misfire, or clear it and see if it returns.
I removed the 2 converters and straight piped them. Didnt even clear the codes. The engine light went out on its own. runs much better,next is spark plugs and I'll just drive it.
