Features
Performance
Due to the characteristics of the B58 engine,torque is exceptionally high up to around 2000-4000rpm, but tends to drop significantly at higher revs due to the turbo's capacity.
The LAPTORR exhaust is designed as a performance muffler. Its low friction promotes turbine rotation, resulting in excellent high-rev performance.
It also considers exhaust pressure control, so you won't feel any torque drop in the low-to-mid rev range.
Sound quality is also prioritized.
In Sport+ mode, the clear, pleasant exhaust note at high RPMs is incredibly race-inspired!
In Comfort mode, its simple construction effectively suppresses "cavitation noise."
Volume
In Sport+ mode, the volume is optimized for the sporty sound and quality heard in the driver's seat during full throttle.The Supra's cabin insulation is quite high, so the volume heard outside might seem a bit loud.
With bootmod3, the exhaust bubbling sound becomes more than sufficiently loud, allowing for a wider adjustment range to easily match your preferred volume/sound quality.
In Comfort Mode, during steady-speed cruising without acceleration, the volume is set so you can comfortably converse inside the cabin, taking advantage of the B58 engine's characteristics.
