So a high flow cat from carsound...I heard that putting a high flow cat on can actually drop power, like on lowend. I have I/H/E, would putting one of those on actually increase horsepower or just give the exhaust more "flow"...sorry for asking so many questions but I'm new to cars so I try to get as much information as I can. Thanks in advance.
