ok I took out all my resonators, put in two high flow cats and left the stock mufflers, and put straight pipes to the muffler,car sounds like well, i would say between a vette and a viper , i lost a bit of low end but holy crap did i gain at 30mph plus. I have always been getting around 275 miles to the tank, Now after the apr 25th meet, and the new muffler setup my TRAC OFF/CHECK ENGINE light went on thats usually the first sign of a o2 sensor i will be checking that out car has 130k+ and is a 92 , can my new muffler setup be the cause of this? Any Brainstorming

aside from the subject its a VIS, mufflers are custom straight pipes
