Does Magnaflow make a complete cat-back system, or just sell a muffler specific to the '98-'02 Accord I4? Or, is there a cat-back manufacturer that incorporates a Magnaflow into their system? How much more hp & torque will one realize using a complete cat-back system vs just installing a Magnaflow muffler. And, lastly, any recommendations re: low restriction cat converters. (my son's 2nd gen Integra barely squeaks thru smog in NC w/ one he got from Summit. . .) Thanks.
