Whats going on everyone! Im new to the forum. My name is david I own a 2002 grand prix gtp with a K&N Filter cone and U bend removal. I am planning on making the car a decently fast car but I am also going for looks. My future plans on monday include 3.4 pulley, Lower temp NGK plugs, 2 12" T1 Fosgate subs with a P1000.1 Amp, and Muffler delete and 2.5 inch resonator. Anyone know if the muffler and bigger resonator upgrade sounds good.
