The stock joint pipe is not only narrow, it also has flattened sections which severely limits the performance gains from fitting a high efficiency manifold.
However, our new pipe has its sections welded together to maintain a wide Φ60.5 diameter throughout with additional weld beads on the inside for rigidity.
Unequal length: 4-1 design for torque and response
The FA20 boxer engine inside the Scion FR-S/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.
The increased diameter and flow capacity improves exhaust efficiency whilst reducing secondary exhaust pressure. The ver.2 was developed to cope with the demands of advanced 4G63 tuning. In addition, the 74% overall weight reduction improves the vehicle’s responsiveness.
Tomei Catless Straight Down Pipe dramatically improve exhaust flow and significantly reduce over 53% of weight vs. stock down pipe. Addition to massive torque and power increase, lightness dramatically improve handling.
OUTLET: Lost-Wax casting require NO welding thus deliver superior precision and strength.
Last Sunday the 27th of April was the JAPAN GRAG OPENING FESTIVAL at Sendai Hailand circuit.
Unfortunately, this full 400m drag course(only this left in Japan) will close in this September. there are only three races left. we all miss it.
With an unexpected result at Irwindale, see how Yoshioka did at the final round of Formula D.
SC Films have been producing some very creative short films recently and they are rich with content and creativity. Check out this all new video that’s focused on a group of AE86 enthusiasts. Not the regular skin and bone type owners who don’t want to spend a cent on this car. These guys all out. They spend money on the AE86 and they USE it! No garage queens here.
