I see your concern for MPG with your Truck. Take a look at these. This will get you 50-54 MPG!!!!!!

Try installing one of these in your garage. Problem solved.  

I'm not really concerned about mpg. It is what it is. I'm just pointing out that my mpg increased after the Borla was installed. 

My daughter has a Prius though 

She can go from Tomah Wisconsin to Rogers Mn on less than 4 gallons of gas . 200 miles. Takes me about 9 gallons in my 5.3

If I was speaking to you I would have quoted you . I was posting to the "Topic" i.e. @bmartinez2086.  

 

"I have 2019 Silverado 1500LD stock to the bone. If install a cat back exhaust just a simple street 40 series flowmaster or a super10 flowmaster. Will it hurt my MPG? IF so do yall know by how much? I've never owned a truck I've only owned Camaros and Corvettes so this Pickup Ownership is new to me. "
