Big black dual stacks would look better than the chrome BUT I think your truck looks really nice as is!....looks tough...

 

Another muffler option to look at is the AeroTurbine series. If you have 4" piping under the truck, look at the Aero 4040 or 4040XL (the XL is a bit longer and has a built in resonator). If you are running 5" under the truck, the Aero 5050 or 5050XL is what you need. When I had my 4" TBE I ran the Aero 4040 and now have the 5050XL on my 5" TBE. I really like the deep note it gives the truck but don't hear it in the cab while cruising. Obviously with stacks you are going to get SOME in cab exhaust noise, but the Aero mufflers might get you closer to what you want.

Another option I have heard good things about is the Hushpower (made by Flowmaster). They are pretty pricey, however.

 

I have 7in black stacks on it now....

i found some sound clips the donal sound too quiet, the aero sound nice tho, id stick with the non xl i think. Ebay the best price on that one? what a resionator for? Thanks

 

The resonator cuts out the drone. I didn't notice much of a difference, sound wise, between my 4040 non resonated and my current 5050xl resonated model however.

Go to http://www.ourdealsrock.net/ They have about the best pricing on them I have seen. They are who I ordered by my 4040 and my 5050XL from. They were running a sale around last Christmas where the 5050XL was only ~$100.
