Description
Description
The FA20 boxer engine inside the Toyota 86/Subaru BRZ can be said to be the successor to the EJ engine. At Tomei Powered, through our extensive testing, we've produced numerous EJ engine and exhaust parts. By applying our knowledge and experience of EJ engines to the ZN6/ZC6, we conducted even further tests to produce 2 new exhaust manifolds with different characteristics. Using this in conjunction with our new joint pipe, released at the same time, can yield even better results.
SPECIFICATIONS COMPARISON VS STOCK
- Unequal length layout for improved torque characteristics.
- Improved exhaust efficiency through catless design.
