Invidia makes exhausts for skunk2 now.
I wouldn't get one because it's a canister style muffler like the A'PEXi N1, HKS Hiper, 5Zigen Fireball, etc etc etc. To me, all canister style mufflers sound particularly obnoxious on low-displacement Hondas.
Other exhausts I would consider (i.e. full stainless and not too loud): DC Sports, RS*R Exmag and Tanabe Super Hyper Medalion.
