    Default Another Exhaust Question

    Sorry to start another typical "what type of exhaust" thread. I searched through posts and read up some and listened to many clips on youtube, but I am still not really sure of what direction to go.

    I have a 2010 5.3L Sierra with the flex-fuel option. I am looking for a simple cat-back exhaust that is in the middle or lower range in loudness around 400 dollars. Just a little louder than stock but with a nice rumble. I was thinking either magnaflow or Borla. Any suggestions?

    Hopefully my following posts will be less painful to answer.

    Good quality, but low price is the Heartthrob exhaust. Made in America and is good quality and sound. Jc Whittney carries it if you interested.

    Not sure what type of impact a flex-fuel vehicle has on exhaust sound, but I am running a magna-flow. It's not too loud (but definitely noticeably louder than stock), so I don't make my very close neighbors mad, and it does have a nice deep rumble. However, it can make a pretty good roar when I put my foot on the gas and run up the RPMs.
