Gibson cat back exhausts arent worth it unless you are replacing a rusted out factory system. Mine sounded just like stock, replaced the muffler less than a year later with a straight through MBRP muffler and it sounds awesome

 

I agree with Miles. Gibson is too quiet, it just looks cool. I started with a dual Gibson system on my truck then later ripped out the muffler and put a flowmaster 44 in....... MUCH better. Then I got bored with the duals and a put single 4" out the side with a flowmaster 10 series. We'll see how long that lasts before I change it again
