Flowmaster 40 series, sounds amazing. Purchased and install by a local shop for $90. Can't beat it, easily the best mod under 100 bucks.

I have the banks monster kit and the Max Energy Hypertech chip set to normal unleaded. Big improvement over just the Powerade air intake. Great sound too.

I wonder if the sound is decieving? I wish there was a simple and available way to esatablish a baseline before installing these things so we'd have something objective to go on.

Maybe something as simple as in a certain gear you can pull this hill at X mph. After installation I could pull the same hill at X plus?

There are enough people ,who say there is no difference beyond a lighter wallet, that I'm sceptical.

I have the banks installed on my rubicon. I like the sound and I could notice a little more torque. But I did see a drop in MPGs (might have something to do with the Trueflow XDI). Overall though I am pleased, in the future i may add new banks headers to go with the exhaust.
