If you dont want to put headers try first to remove your secondaries but keep your primaries . If you try this and not enough for you, then add another pipe from differential to rear to have quad exhaust

Remove secondary cats, muffler and resonator. Install an MagnaFlow X-pipe (part # 10791) where the secondary cat is and have dual pipes all the way to your tips. It'll sound heavenly.
