I have finally gotten my new exhaust setup in. High flow cats, Mag Resonator and Borla XS mufflers. Before I install them, should I do anything about the downtubes. What do they do.
Once I do the exhaust, is a 5% pully an nice upgrade. Is it safe for my engine and will it help much. What are the fuel pump ugrade sizes and where can I find one. Will a slightly larger pump dramatically reduce my mpg? I have not done anything to my TB or MAF yet, should that be next and is it expensive. Thanks for the help.
