So, you have been bitten.
Ok, so now you want the exhaust and other mods, it's simple, it all depends on your budget, that will be the limiting factor here.
You can go w/ only a free flow muffler and leave it stock or go all out and do a complete system from the downpipe to the tip.
Magnaflow,dynomax,etc.. for mufflers are good and not too loud.
The "wicked wheel" will give more whistle but less torque I believe, most claim will help with the surging problem while towing.
I sincerely believe our trucks can use better air coming in, and more exhaust going out so you can attack both territories.
I use a S&B complete air intake kit and was impressed with how good it was and how cheap it costs.
I use magnaflow mufflers, 2 of them, 1 was still loud to my taste, 2 is just right but I run a full exhaust built by my local shop, Miami Mufflers.
Have fun, I kow I am!!
