I'm working on outfitting my new to me truck with an exhaust. It's currently got a stock exhaust setup and has the 460. What I'm thinking is a set of Hedman shorties which have a 3" collector, to a reducer right after the collector to drop it down to 2.5", run both banks into a dual 2.5" in, single 3" y pipe, into a 3" hiflow cat, 3" pipe the rest of the way and a Dynomax Welded(probably) 3" in, 3" out muffler.

What do you think? Should I make any changes?

 

Everything but the shorties. If you're gonna take the time to install headers go with long tubes.

 

Sounds like a good setup to me. Good choice on the muffler. I have them on my Mustang and really like them.

 

Sounds like what I built for my truck, I used mendrel bent tubing sections and cut and welded the pieces one at a time to get the proper fit and clearance, and it certainly flows great and sound awesome. I got no problem with shorties on a 460 either.. it really doesn't need much help to produce big torque.
