Should I just go with a magnaflow or american offroad muffler?
How much is hard to say.
Has moderate wear - scratches, scuffs, rusts, and oily residues.
According to your table the ideal pipe diameter is 2.
My truck has relatively low mileage and still under warranty, but Navistar keeps saying the EGR issue are not cover.
In my mind, I see the very lowest back pressure as being the best, well designed will cause a vacume during cam overlap, and so gain erotic massage 818 performance with a full charge of clean fresh air, any form of back pressure will negate this.
Try to get original equipment manufacturing OEM parts for the chassis, body and interior if possible for a more uniform look and therefore a higher resale value.
Im having a hard time following the accepted norm, that a smaller pipe, so restricted, makes for better bottom end torque.
This is what I am considering.
What planet is that on??
