I was looking into cat back set ups for my b4000 with the 4.0 sohc, just wondering if anyone could give me some input on what brand would be the best? i want something that sounds good and deep outside, but quiet in the cab. thanks! 
Aero Turbine.
Well, you have a 2.3Dude I tried one of those and it sounded like crap haha
You probably also had it installed with the stock tailpipe just like the 40 you didn't like, huh?Love my Gibson. Loud enough that it's obviously not stock but not loud enough to annoy you inside the cab. I just got the aluminized one because I couldn't afford the stainless and it's almost 10 years old now. Fit like a glove too, removed the stocker and installed the Gibson on my 1/2 hour lunch break with no problems.
