Brospeed makes one i think
If you want the best, get Ripp headers (about $450, GB awile ago, idk if it's still going or not) and have a exhaust shop make you a custom cat-back system with a nice muffer (no fart-cans please). All in all, I've heard people getting systems like this for around 600-700 dollars (headers included), which is about the price that a aftermarket cat-back would cost you, and you can get it in whatever size you want. Just be sure you don't compromise for any cheap shit systems, you get what you pay for.
Good luck
