I just bought a new 06 2500 quad cab 4x4 the other day and i'm wondering what can be done to as far as the exhaust goes to make it really sound good. It's just too quiet the way it is. I don't want to spend a lot of money putting on a aftermarket exhaust system or anything and the cat converter can't be removed or it will void my warranty. I'm thinking just take the muffler off so it'll be a straght pipe from the cat convertor. How will that sound? I can have it done for around $50. Any help is appreciated.
