    None of these catbacks throw codes do they? I heard someone say that after they installed their catback, they didn't go into V4 as much...? I don't wanna mess with the way the truck is designed to run.

    So, there is no solution to this?

    I was averaging 19 MPG and a best of 20.5 MPG with a mix of city and highway... All of a sudden I'm only averaging 17.5 MPG to 17.9 MPG. I have about 14,500 Miles on my rig and I haven't changed anything. I noticed this right before my last oil change and my tire pressure dropped about 5lbs. I was expecting the fuel economy to go back up after they put air in my tires, but that doesn't seem to be it. Any thoughts? Was I just breaking in and now this is my true mileage per gallon? I went a little over on my oil change, but I wouldn't think that would affect it...? Thoughts?

    Hello, I'm new to the forum and I'm interested in a Borla system. I heard the GM Borla Catback in person today and though it was a nice sound, it really just had that "stock rumble" to it and I'm looking for something a little more aggressive. I am leaning towards the S-Type, but have concern about the drone. I don't know if the S-Type is the sound I want either, but I'm a little scared of the ATAK as I'm sure it has the most drone and longterm may be annoying. Does anyone run the S or ATAK? Thanks, Matt 2014 GMC Sierra 1500 Crew Cab SLE All-Terrain 5.3L 3.42
