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.    

Complete performance exhaust solution add power, sound, and throttle response to the 987.2 Boxster/Cayman; includes Maxflo Mufflers with Deluxe Dual Style Tips, Sport Headers, BMC F1 Air Filter and optional ExperTune Performance Software with Handheld tuner.

    Sport Headers, Muffler & ECU for 2009 2.9L Cayman

    Posted by ABD-Houston on 14th May 2014

    Installation of headers w/ CATs, pipes, mufflers and tips was straight forward with no problems at to fitment. Had to remove some of Porsche's O2 sensor clips to give additional length to reach bungs. Because of the size of the header pipes, some header bolts are tricky to torque, but can be done. Great sound, no drone (6-six speed tranny). Headers/Muffler alone had a noticeable improvement in performance. Reprogrammed ECU gave very noticeable improvement. No CEL. 2 weeks in and very pleased. Customer service was excellent.
