+ Detailed Product Description

aFe Exhaust Headers Upgrade for Porsche Boxster S 3.4L 981
  • Max gain of +22 HP & 22 ft. lbs. of torque
  • Incorporates 3-to-1 mitered collectors
  • Available with or without catalytic converter
  • Retains factory O2 sensor locations
  • Optimized equal length tubes for improved flow
  • Constructed from 304 stainless steel tubing
  • Road version includes 400 CPSI catalytic converters

The aFe exhaust header upgrade for the 981 Porsche Boxster S 3.4L adds an extra 22 HP and 22 ft lbs of torque. There are two versions, depending upon a street or race application. The road going version features a high flow catalytic converter on each header, while the race only version has no cat.

The headers are constructed of near equal length 304 stainless steel tubing with thick flanges to ensure a leak free seal. The smooth curves and increased diameter of the header tubes, help to remove restrictions and keep exhaust gas flowing smoothly. This improves power delivery and in particular, throttle response with low end torque at lower rpm.

+ Performance Specifications

+ Our Opinion

High quality set of headers that fit extremely well and maintain the factory O2 sensor locations. The headers produce a healthy power and torque gain that can be optimized with an ecu tune and a free flowing exhaust. For race applications the cat-less version is the best option.

+ Installation

Installation of the aFe exhaust headers is quite straightforward. aFe does not include exhaust manifold gaskets – we’d recommend you replace these rather than re-use them. Also, make sure you have the torque specifications for the manifold to head available – breaking a bolt here can be expensive!

f you’re not comfortable with installing yourself, we’d recommend you search our directory for a local specialist who can install this for you – or contact us and we’ll recommend a friendly local specialist shop for you.
