Thankfully I have almost a year to consider header choices.
I'll definitely do some research on shorty vs long-tube
Thanks for the heads-up!
So until next year when I do a stroker build... I'd be looking at...
3.0" single tube cat-back, rear cat delete, front cat hollowed out and larger 4.10 or 4.27 gearing.
So this is still the plan for right now.
But the 3" cat-back will really just be me buying a muffler and going to a shop to have them do the 3" pipe work from cat-back.
I don't want or need stainless, since this is Central Texas and I don't have to worry about rust anytime soon.
That, and I prefer to have a single side-exit that doesn't look shiny.
I would only want shiny if I had dual rear exhaust, which I'll never have since my dogs will be spending a lot of time in the rear hatch area (don't want fumes back there).
That Flowmaster 50 seems to be a winner.
I love the way it sounds.
A bit louder than I wanted, but it's so beautiful that I want it anyways.
Some videos I found with sound of the Flowmaster 50 + our 351W.
All but one are Broncos, with the 4th being a 90's F150 351W:
