If you're after performance with a glass pack look for the design without louvers. Thrush makes a good one that doesn't have the internal louvers like Cherry Bomb and others. Thrush has a perforated core and is consistant in diameter from front to back for the best flow. The louvers restrict flow. Flowmaster's don't flow anywhere close to a good glass pack.
