Improve both the sound and the power from your 981 Boxster/Cayman with these sport headers. Our Sport Headers use 200 cell HJS catalytic converters which improve exhaust flow while still cleaning your exhaust gases.
These headers will give you a significant increase in volume, and a smooth sports car sound.
These dyno designed headers feature smooth mandrel bends and a 3-1 collector to get the most power out of your 981. Paired with a Maxflo Exhaust at 6600 RPM there we saw an increase of 13 whp and 10 ft/lbs of tq and these gains are carried throughout the rev range for great under the curve power.

INSTALLATION NOTE: To ensure proper header seal, after initial heat cycle, tighten all exhaust bolts to the OEM torque specs.
Why We Choose HJS Catalytic Converters:
HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.
