The order was tower bar, suction kit, muffler, and ram air.
Speaking well, it was a quiet and quiet MAZDA3, but I could not hear the exhaust intake sound so much that it was not enough to ride with a manual transmission, but after installing the muffler, especially the ram air, I can feel the sound information. became.The torque also rises from the start of running, and I feel the strength and strength.

It feels like I'm finally approaching the sports car I envision. I would especially recommend it to those who are riding a 20S MT.
The handling is also comfortable thanks to the tower bar!
Ram air It takes time to deliver, but I think it's worth the wait.
