How ACE headers are made

ACE Header is considered the best exhaust manifold for the Toyota 86 / Subaru BRZ / Scion FR-S. Here's a quick look at the production process of the ACE headers at their factory in Taiwan:


CSG has used ACE headers in their BRZ with great success, winning Super Lap Battle's Enthusiast RWD class two years in a row (2017, 2018) as well as SoCal's 86CUP Street & Modified classes. CSG has helped develop base engine maps for naturally aspirated and boosted applications  -both supercharged and turbocharged variants.


The following is a dyno chart of a 2017 BRZ with:

ACE Header on ACN91 gas (California 91 octane) : 18% HP gain
ACE Header on E70 mix fuel: 25% HP gain

The ACE Header boosts power across the whole RPM range, with even greater gains when paired to the ACE Front Pipe and a Flex Fuel (E85) kit. Our Power Package for 86 / BRZ includes ACE Header, Flex Fuel Kit, tune and more!

Besides the ACE Header 350, there are several specialty models for left-hand and right-hand applications to choose from. If you are not sure which one you should get, just ask us!
