Once I get my new truck broken in, I want to get some guages on my a-piller. What will match my dash gauges and be sufficant to see easilly at night? Also After going half deaf with my 2000 and barely never being able to hear my customers on my cell phone, I am very pleased with the quite sound of my new Dodge. What exhaust upgrade can I do that will bring sufficant flow yet limit the sound to a quite rumble?
