Maybe you should contact the people you bought it from because we haven't received any complaints from our customers. You sure you got an actual Greddy exhaust

There is definitely hp gain. Rated at 15whp. As for weight I'd have to find out

A catback with a 15whp gain? Do you have any dyno proof to back that up?
