I am looking for advice on what cat back system to install. I have an S & B CAI on my 2011 5.7 hemi. That increased my hp(not sure how much, but noticeable). I have also gained 2 mpg. The engine gets in Eco mode easier and stays there as long as I keep it under 72 mph. I couldn't do that before. I want to install an exhaust that ads more HP and mpg. I do a lot of hwy driving, about 40-50k a year. I also pull a trailer and bikes into baja and the desert. I need the power in the dirt and sand. Any suggestions for me(serious ones)?
