    Default Exhaust & Intake question

    I have a 2007 Silverado 1500, flex fuel 5.3 and was curious what everyone recommends for exhaust as well as what is a good intake to put on.

    Has anyone heard of Mac Performance? Do they make good products?

    Looking into improve mpg and get some performance as well

    Thanks for all the help...

    I would build a custom intake out of Spectre intake parts. Many users on here use Flowmaster exhaust systems, and that is what i plan to go with.

    -custom air intake
    -painted dash
    -footwell lights
    -Strange Performance stickers
    -exhaust coming soon
    -Xplod Head Unit with iPod connectivity
    -12" Sony Xplod woofer
    -Majestic 400 watt amp, bridged

    If at first you don't succeed, then skydiving is not for you.

    Cool Exhaust & Intake questions

    Gale Banks has nice exhaust and cold air for your gas truck. There alot of good quality exhaust and cold air kits out there but I thinks the Banks products cant be beat.

    Definitly Flowmaster 40's if you want to be heard.

    I will be going with Volant and of course a tune afterwards. As I suggested in another thread, go to an exhaust shop and have them make you a true dual exhaust system with a couple of Flowmasters on it. This combo should net you about 3 MPG and around 40 HP.
