Depends on the baffles, if they even come with any. No baffles would be close to open pipes. I baffled the bejesus out of mine to get my low end torque back, after trying them out completely unrestricted. I have Paughco s and the baffles as they come new, are a weak, tinny, thin, galvanized joke. Ask for an image or two of the baffles and a better answer will be forthcoming.
