Currently rocking this on my 2024 Si, and I notice a night-and-day difference. My shifts feel pretty solid and concise. To include, the upgrade allows my build to put down more power, reaching upwards of 300 ft-lb of torque. The product is made from solid material as well with no complaints.
This piece is spotless and with the bronze cerekote it’s top tier
Build quality is second to none. PRL and Mishimoto have competition for sure. Durable, no heat soak, with all cold side through exhaust, 27Won has surpassed my expectations. Fitment always easy as well.
Fit good looks great on a PRL expansion tank
