Exhaust Options

[livingez_123]

I have a nice set of true duals on my Denali now. factory manifolds, cats and a custom pipe from the drivers side over to the pass side for the duals and back to a pair of Magnaflow Stainless mufflers.
I would like to go to a set of long tube headers for help in the Torque dept. run a pair of High flow cats and then build a new crossover pipe to the dual exhaust.
Now my question is has anyone tried a pair of corvette manifolds?
I'm just looking for other options because the shorty headers don't help enough to offset the cost of them.

I pull a rather big RV and I miss the Torque of my Cummins diesel and I know my 6.0 will never have the same amount of torque......ever. it just needs a little help.
I dynoed my Dodge and at the rear wheels I had 366hp and 784ft lbs of tq
Short of putting a Dmax in my Denali......

just the ramblings of a tired mad man.

What are your reasons for wanting to use corvette exhaust manifolds? Why not just get a set of long tubes that are made for the denali? There are a few on here that have done it.

IDK, they flow better, the cats are in the same place for easy hookup. I was just curious if anyone has tried them. I have no issues with the long tube headers. I would just have to find a short cat that will still give me room for the crossover pipe. I'm a neat freak and I like stuff to look like it was meant to be there and not an afterthought. I know it's just a driver but detail is important to me.
