A cat-back exhaust replaces everything from the catalytic converter back to the tips. It changes sound and sheds a little weight - it is not a serious power mod on its own.
why this one — SPD does not publish a power figure for this system. The GX Series uses a sound-wave-canceling muffler design meant to sound aggressive without raising cabin drone on the highway.
