I have had mine for 9 months now, both headers and cat back with NO CATS!. It sounds loud, tough and aggressive. There is borla, Belanger, corsa and B&B in our driving group, and B&B gets all the comments. Makes a stock car sound like it has a built motor!
I have and like the older style setup with the oval tips, not the new corsa like one's that comes with x pipe setup. If you look in the vipermag B&B advertisement, that is my car, and they offered me a free or at cost of materials upgrade to new X pipe/Round tip version for using my car in add. I'm keeping the original, they sound and look alot better.
