that picture is deceiving. i have a 4" bullydog exhaust, aluminized as well, and it's not that shiny at all. that looks like a stainless steel kit in the picture.

fwi, my bullydog was easy to install, came promptly but the box was destroyed and i feel i over-paid for the kit...but that's cus i know people in custom fab shops and once you have a jig setup, kits become easy to make.

Get a 7".

 

I know a fella with an 04 dually that has 6in front to back and that is a big honkin set up, you could just about weld that from the inside. It sounds good and his truck runs great but it was expensive! I think about $900.

 

Hmmmmmmm sure would like to hear a 6"

 

6"!?!?! Might as well just JB Weld some coffee cans together and hollow out the middle of them!! That can be done for cheap and you will get the coffee aroma mixed with diesel exhaust.................that should be a new flavor!!!!

My wife drinks TONS of coffee, I will hook a brotha up!!!

I bought the Motoblue dual 4" exhaust 5"tips and modified it to exit in the rear and i love it(off of ebay or RPMoutlet.com). It makes my baby sound like a big rig.
love it.
