Personally, I'd run the 4", if just for appearance. Anything smaller than that looks wrong to me somehow. (And to look really "correct", they will need a chromed / polished stainless "heat shield" wrapped around 'em..) Now, that 4" can run into clearance issues, so under the truck might have to be 3".

Sounds like an invitation to post-up our stack pictures?

For the most part all conversions have 3'' down pipes to clear the firewall after that than a 4 '' can be used .

My truck has a stock dodge down pipe until I get past the np205 t-case and then it goes into a 4'' 10 ft long pipe and a 5'' tip.

I've got 3 1/2 from the turbo back to the 4" stack. I had 3 1/2 laying around so that is what I used, I would have rather used 4" all the way though.

All the ******* hillbillys around here with diesel trucks have 5" or larger stacks.
In my own personal opinion, anything over 4" on a pickup truck looks like ass, not "bad ass" at all.

Gonna have to agree on that one. Even the big rigs with 6" + Stacks look odd from a distance, but, in the end it's all proportional.

Speaking of proportional, I saw a crown vic earlier this week that had 24" wheels that had more ground clearance than my 2500HD . That's just sad IMO uke:

4" stack...66 Bronco

Well, some of it is a 66 Bronco.

What kind of muffler is that on the bronco?

 

[LincTex]

That looks OK. Yeah, what muffler? Got a bigger picture?

4", two chamber Flowmaster.
I know the the design of the Flowmasters are not optimal for diesels, but with the over-size it has not caused any problems.....
