I know y'all leave cats or change them because it is illegal to run without them. My question is, would you gain any hp if u ran without one, illegally? I know the mustang guys run without them, because they are always talking about gettig offroad H pipes. Some of those guys claim to gain about 20 hp when getting them removed from GT exhaust. Then again, they have 6 cats too. It looks to me like if they would gain then y'all would gain a little too. Any ideas?
