I am not at all knowledgable about performance upgrades, so I figured I'd ask you all what to do.

I would like to increase the performance of my 2005 FX4 SCrew without doing any engine modification.

First of all, I mostly drive on the highway at 50-80 MPH - I don't really do much "offroad" driving, with the exception of 12" of snow during the winter when I want to go skiing. Figured I'd explain how I use the truck to help everyone with recommendations.

One thing I know I'd like is a shiny, dual, rear-firing exhaust kit with Flowmaster 40's to get a nice low growl and open things up a little bit. Any recommendations on a good kit? Any do's/don'ts on the Flowmasters? I am in NJ and I think that legally rules out my ability to use an H-Pipe, correct?

After the exhaust, then what? Programmer? Air intake modification? Replacement air filter? What else?

I am looking to squeeze as much as I can out of a small amount of money.

Thanks!

Is that what you are talking about? This only has one muffler. Was that recommendation intentional? Why only one?

Thanks
