I have a 05 Silverado z71 5.3 and I am going to put exhaust on it. I was thinking about putting Gibson Super Truck on it. Can anyone tell me what exhaust or anything else I could put on my truck to make it extremely loud.

 

Cut out the cats and straight pipe it

 

I trying to stay away from cutting my cats off cause I did that on my last truck (5.4 F-150) and it didn't sound that clean unless I got on it.

 

Leave the cats and dump the muffler(s).
