I have been thinking of removing the magnaflow highflow cats that I have behind the gibson shorties. Anyone think this would be a bad idea? Would I lose any low end or gain any top end? Im sure if I did I wouldnt be able to tell anyway. Would I see any losses in quality of sound? Ive got gibson shorties to a flowdisaster super 40 that has two turn downs. Would it sound raspy at all? Can Allen fix it to where the SES light wouldnt come on after removing the cats?
