What do yall think about the set up I want. I have some hedman headers (Long) that are thermal coated and I want to get them installed running true duals somewhere out the back to 1 1/2 pipes. How much will this install cost me? Do yall think I will burn valves? Where should I run the pipes?

My mistake on the mandrel benders.
The place i go does have one though.
As for them costing 100k, uhhh.. maybe not.
Muffler mans are picky, but have good warrenty. I know the owner of the one i go to. so he cuts me a deal, and i get good work.

If you want the duals for look, set up a sinlge intlet dual outlet downstreatm of a 2.5" Y pipe.

If you are asking them to set up your headers from the block back... be prepared to take it in the pooper!
Is this sizing okay? I'm wanting optimal sizing for gaining power without losing torque. Also, what is a good, cost effective highflow cat to go with?

O2 sensor problems with long tubes?
Long post please bear with me.
I need to replace my exhaust on my 94 f150 5.8. The down pipe flanges and manifold studs are rusted to non-existance. To replace the flanges I would have to cut the pipes, install new flanges and reweld the pipes back together. The manifold studs look like a whole bunch of troubles to replace.
So my options are:
1) Fix using existing parts.
2) Fix flanges, and install a set of pacesetter shorty headers that I had bought and never installed for my '92 F150 5.0 (would need to modify for the 5.8 EGR tube).
3) Buy longtubes and have custom exhaust work done.
I wouldn't mind having a some power increase as a byproduct of this project. I have read in my searching that shorties don't give any increase in performance. Long tubes would take additional money and time. Also, I had a friend with long tubes on his mustang and he kept having problems with his O2 going bad (maybe exhaust too cold?) until he swapped them for the shorties.
Opinions?

These long tubes were not set up properly in the mustang. I bet the o2 sensors were too far downstream or he was having other induction issues that the long tubes magnified... just a hunch. It is imperative the o2 sensors are the same distance from the cylinder head as before. A good exhaust shop will weld in the o2 bungs and EGR pipe in the correct location. You will not have any of these issues with your truck and long tubes. Just a big fat grin with the extra power punch!
Good Luck

I see Ford Motorsports make stainless shortys, Why dont they make full length longtubes if they make more tourqe and Hp. I think GM offers the same for cars like the GTO,Vette, etc. Maybe its a direct replacement thing.

It won't take you anymore time to swap in the long tubes, assuming your stock manifolds have kicked the can. I wouldn't waste any time or money on the shorties. Sell them on craigslist or ebay.
