4AG（AE86）
Studies in balance the effects of noise and performance have enabled us to reach a good specification. Improving the sound by reducing the unpleasant droning sound when "accelerator-off" by the use of a resonance pipe (resonator). Also introducing a cool metallic sound particularly when "acceleration-on" which resembles that of a jet engine at takeoff.
Twin silencers used to make a more intoxicating sound.
Titanium end pipes designed with "melted edge" to improve robustness, along with the blue tint to enhance a sporty look.
Center pipe (Stainless): Ø60mm + Rear branch part (Stainless): Ø50mm x 2 + Twin silencers (Stainless): Ø150mm diameter + Tail pipe (Titanium): Ø100mm
