    .....Cat Back Exhaust
    .....A Tune Either Hand-Held or Custom

    These Performance Upgrades/Mods.....will give you the Best Bang for your $$$$.....if you go to the Performance Section of the Forum, there you will Find a Boat Load of Information, regarding the Mods I've mentioned.

    Hey Mike, As long as the subject has been brought up again; I wanted to say that I got a lot of good info from you as well as others from this forum. What I have done so far; I bought a K&N stock air filter replacement. I just ordered the Diablo predator tuner. looking forward to getting it! I have got an appointment to have a catback exhaust put on. I went to the local garage where they custom build them. they have been doing it for many years. I will see how it does when I hook to the camper next year. meanwhile... save my pennies for maybe a gear change and/or a cam. thank you for all of your information,
