Need Power What Should I Do Next? Thanks

[ewalker302]

Thanks again guys.

Heres what I am considering now.

Installing a cat bacs sys.

I want to get shorty,(stock length headers) any reccomendations (price vs. performance)? I have already installed the off road h pipe and want the headers to bolt right up.

But will the headers give me much improvement without modifying the stock intake manifold or heads?

After making these mods, will a 65 or 70mm MAf make much difference?

Thanks for your time and responses guys.
You are really helping me out.
