Well originally I had true dual with the two resonators and two stock cats with flowmaster mufflers out the rear. I noticed my mufflers had rusted holes in the and my driver side manifold had a leak in it. I've decided to change the manifolds with new ones and have gutted my two cats and will run pipes out the back of the truck.

I've finished step one by cutting all my pipe off at the manifolds (I'm not worried about the o2 sensors bc mine were bad.) about a week ago and alls I can say is DAMN!!!!! That ***** is loud. Once I get the new exhaust on there how much quieter do yall think it will be.

 

depends on if your keeping the flowmasters or not
