Features
Performance
Due to the characteristics of the B58 engine,while torque is extremely high up to around 2,000–4,000 rpm, there is a tendency for torque to drop significantly as the engine reaches higher RPM ranges 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 ranges.
Care has also been taken to control exhaust pressure, 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 set to deliver the best sporty sound and tone when the throttle is fully open, as heard from the driver’s seat.Since the Supra’s cabin is highly sound-insulated, the volume may seem a bit loud when heard from outside.
The exhaust bubbling sounds produced by systems like bootmod3 are more than loud enough, so you have a wide range of adjustment, making it easy to fine-tune the volume and sound quality to your preference.
In Comfort Mode, when driving at a constant speed without accelerating, the volume is low enough to allow for comfortable conversation inside the cabin, thanks to the characteristics of the B58 engine.
