The catless "Track Only" version of cp-e's QKspl downpipe for 2011-2014 F-150 EcoBoost - same downpipe, no catalytic converter.

why this one — Cheapest of the three QKspl variants since it skips the catalytic converter - track/off-road use only, not street legal.

where the number comes from

Cp-e.com product page states "5% gains throughout RPM band" for the QKspl downpipe family - a manufacturer-published percentage claim, not an independent dyno number.

heads up

CATLESS - this variant omits the catalytic converter entirely. Off-road/competition use only; not legal for street use in any state with emissions inspection, and not legal for sale or use in California.
