4.7L Headers

Would putting shortty headers on my 07 JGC 4.7L give me a little bit of a power boost? Im still running the cats, i can't seem to find a company that offers high flow cats.

There is no room for us to sport headers which is why you will not find any.
It would be nice to fit them thought, might have to go to an expert to custom make you some.

Shorties are pretty worthless in terms of performance gains. Mid-Full length will gain you much more oomph.
