Catless with mufflers
Hey I got a 2005 Acura TL with the stock exhaust. I was wondering if the car would sound raspy if I deleted all 3 catalytic converters and left all the stock mufflers and resonator on. Also would I gain any power

Mr. Detail
It won't damage anything but if you just gut the primary cats you'll have a check engine light plus you won't pass any emissions testing your state may have. You'll also have to add an additional resonator to cut down on the rasp.
A better idea would be to start with a long tube J-pipe which deletes the 3rd (non-monitored) cat. Unless your state does a visual inspection, you won't have any check engine lights. And there is almost no change in sound level so no rasp.
