Ok I was suckered I'm pulling the POS off and maybe with some new plugs, clean maf, *throttle body , pvc valve, VVT valve it will once again run & get the mileage.

ANYBODY tell me is this a true increase in power & MPG or just sounds good and you think you got something? WHAT If I just removed the resonator? I suppose If I remove the cat I will get all kinds of ECM fail codes? But does all these brands of exhaust cat back systems or is it all for the "...

Should I remove it? is a hinderance?
