Hey guys, recently I took off my cat and I put on a cherry bomb. I noticed that my gas mileage went down 4-5 MPG. I also just put 31x11.5's on but I was wondering if my exhaust could be affecting my mileage. I was thinking that there is not enough back pressure but I'm no expert on exhaust so I don't know. Does anyone know if that could be it? I didn't think that going to 31's would drop my mileage so much, so I'm exploring different options. Thanks
