Features
Performance
Due to the characteristics of the B58 engine,while torque is extremely high from around 2,000 to 4,000 rpm, there is a tendency for torque to drop significantly as the engine revs increase, due to the turbocharger’s capacity.
The LAPTORR exhaust is designed as a performance muffler; its low-friction construction promotes turbine rotation, making it ideal for high-rpm operation.
Careful attention has also been paid to exhaust pressure control, so you won’t notice any loss of torque in the low- to mid-rpm range.
Sound quality is also a priority.
In Sport+ mode, the clear and pleasant exhaust note at high RPMs is incredibly race-like!
In Comfort mode, the simple design helps suppress “muffled” sounds.
Volume
In Sport+ mode, the volume is tuned to deliver the best sporty sound and quality when the throttle is wide open, as heard from the driver’s seat.Since the Supra’s cabin has excellent sound insulation, the volume may seem a bit loud when heard from outside.
The exhaust bubbling sound produced by systems like bootmod3 reaches more than sufficient volume, so the wide adjustment range makes it easy to fine-tune the volume and sound quality to your preference.
In Comfort Mode, during steady-speed cruising without acceleration, the volume is low enough to allow for comfortable conversation inside the cabin, thanks to the characteristics of the B58 engine.
