I noticed on Gibson's web site that they had Gibson Superflow mufflers available in different configurations. Are these the same mufflers that come with their cat-back systems? Do they flow more freely etc.? Anyone know about this? The site had no email for questions. Thanks -- Martin

I have the Super Truck System and from what I can tell and have read, the muffler that came with it is a Superflow muffler. I'd say that they're the same.
