FWIW, I am running Hooker LT coated, Hooker ORY and a hooker 3" in and single 3" out muffler. I did it that way because I previously had a Flowmaster 3 in/dual 3 out. When my flowmaster rotted out again (i had 3 of them on the car) I wanted a different sound and something that flowed better. The hooker aero chamber has a melow tone at idle and a good bark when you get on it, especially if you have a good cam/head setup. The headers I bought used for a steal. I had pacsetter on before. The rotted out so bad the O2's fell into the colector. I would NOT recomend pacesetter. IMO. They are inexpensive and you get what you pay for. My advice, and only as advice, save up for a great exhaust system. Put it on once and leave it be till you want something different. Again, this is all IMO and only for friendly advice.
