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 HX Series is their single-exit configuration, bought for sound and looks rather than a dyno gain.
