where are you guys buying a 2.5 inch magnaflow exhaust kit? I guess maybe it's only available for hatches because I've only ever seen a 2.25 available for zx4's. On a related note, why anyone would change out the exhaust system w/o upgrading the cat to a HFC (or an o/r pipe) to me seems totally silly. Your exhaust is only as good as your weakest link. That tru-bendz kit with the HFC already welded on seems by far the best and most cost-effective option for really, truthfully opening up your exhaust.
