[QUOTE="BluRaySS, post: 1451598, member: 13311"] No offense to the poster, but this is a common no-no. Really bad idea! They are a part of the system for a reason. You will lose torque and MPG doing this redneck trick. The heads, exhaust, and most importantly the camshaft is designed to have the MINOR amount of back pressure a cat creates. Without it you start scavenging your A/F mixture(sucking your raw fuel right out the exhaust) during the valve overlap. No vehicle that came with a cat performs better without it unless it is failing in some way and creating a non standard restriction. Also let's throw in that it's illegal, and can get your vehicle impounded. If the day comes that OK picks up emission inspections it will be too late. It will cost you 10x as much to have it replaced. What is telling you that your cat is bad? [/QUOTE]
