Do you want to buy a cat-back system or build your own? If you want to build your own, yeah check out performance peddler, or jegs, or anything along those lines
A cat back is the exhaust system that starts from the catalytic converter and goes to the tips. And I don't know about the sound, it all depends on which brand you choose
Cat back would be the exhaust after your Catalytic Converters Back to the tail pipe.
I believe most of the after market exhaust will give you a deeper tone. Simply cutting off your factory muffler & installing a flowmaster 40 series muffler will give it a deeper tone.
I myself like the look of Dual Exhaust. Some day mine might actually show up. I only ordered March 7th!!! Here is a link...
I have a 40 Series Flowmaster on mine & it has a deeper tone. You will also need a small 2. 1/4" pipe to piece in as well due to the Factory muffler being long.
Clo650, When you get that kit from whitney. I hope you can do a sound file. I have always wondered about that kit. Started to get it but I wanted stainless.
Fast Eddie, I ordered the stainless slash cut tips. I also just checked with JC Whitney & my Exhaust has finally SHIPPED!!! I'll start a new tread if I can figure out how to get a sound file.
I got a Gibson cat-back on my '08, frankly I think it's too loud. Sounds good outside the truck, too loud inside the truck. Got a new chrome tip with a resonator built in at Auto Zone for $24, that made it a little quieter.
