I was wondering if anyone had any suggestions about what I should do with my exhaust. I was thinking 3" duals with flowmaster and no cats. Also on my 81 bronco with a 302 I ran without cats and it didn't hurt anything, but since the 90 is all computerized would running without cats hurt anything? Such as gas mileage, power, or turn on any warning lights. Any suggestions would be appreciated.
