Forget headers. Always wanted them and will probably get them eventually but for the sake of this post, haven't seen where high flow cats alone have been installed. Can't see where LT headers themselves would make the hp gains. LTs are always mated with no cats or HF cats. The stock manifolds are not awful. They look pretty good for stock actually. I'm thinking HF cats with a tune would yield similar gains to headers/HF or no cats and a tune.

btw I broke down and ordered the Borla S exhaust after all my complaining over the price, which is very high for what it is.
