thanks for taking the time to vid the difference. Ive been wanting to get rid of my 40 flow for a while and this only makes it worse. I swear Ive lost hearing I have to crack the window because of the resonance sometimes I can only imagine what it sounds like behind me when I mash the gas. The plus is setting off car alarms

Is that a full exhaust without the cats?
