I have the FI lth's. With lth, you will get more torque then with test pipes. You don't need a tune with lth, unless you have other mods. Both the FI and PPE are good. Both about equal in power. One makes a little more power and the other makes a little more torque. For sound. Both would sound the same. For loudness. It depends on your choice of muffler. The lth will make any system louder because of no cats.
To install. The right side takes about 1.5 hrs if you are slow. The left side is a PITA. Figure on 6hrs.
