If I were to get an ORY, along with my catless flowmaster catback, would it sound a lot better, or would it ruin the sound? Also lookin for a lil HP gain.

I haven't done it on the Camaro personally, but from prior experience the cat provides some mellowing of the exhaust note. If you take out the cat, you might want a free-flow muffler like a Dynomax Bullet in place of it.
