Product Description

Not for sale in the USA. Only available on International Orders.

The EVOMS ClubSport headers are designed to maximize the potential of the GT3 engine while extracting significant power increases with better designed hardware and more precise engine software calibration.

These headers have been in use on the Shark Werks 4.1L GT3RS for some time now and on EVOMS own-in-house 3.6L car where they actually gave the car an additional 17hp and 13tq by themselves. Their design helps equalize each cylinder exhaust pulse for better exhaust scavenging and consistent exhaust temperatures on every cylinder. Close attention was paid to the exhaust flow into the catalyst which has sometimes been a problem with the OEM headers and has caused premature catalyst failure and cracking of the OEM header before the catalyst with heavily tracked cars. 


EVOMS headers help reduce exhaust restriction / catalyst temperatures but for track use we recommend swapping out the cat for the optional track pipe via the v-band set up. With less dense German HJS cats the back pressure is also reduced compared to the more restrictive stock units. Hand-made in the USA in Arizona @ EVOMS' facility.

Works and sounds fierce with our Shark Werks exhaust set up. See short clip here.

Note: For track usage we recommend using the easy-to-install test pipes in place of the german catalysts. Available for an additional $450. Not for sale in California. For off-road use only.
