Developed Exhaust System for the A90/91 Supra B58

Performance!　　
Due to the nature of the B58 engine, while torque is extremely high in the 2,000–4,000 rpm range, it tends to drop significantly as the engine speed increases, due to the turbocharger’s capacity.
The LAPTORR exhaust system is designed as a performance muffler to promote turbine rotation through low friction, delivering outstanding performance at high RPMs.
We've also taken care to control exhaust pressure, so you won't notice any loss of torque in the low-to-mid RPM range.
　
Sound quality is a top priority!　　
In Sport+ mode, the crisp, pleasant exhaust note at high RPMs is incredibly racy!
In Comfort Mode, the simple design helps reduce "resonant noise."
　
Volume!　　
In Sport+ mode, the volume is set to provide the best sporty sound quality and volume from the driver's seat when the accelerator is fully depressed. Since the Supra's interior is well-insulated, the volume may seem a bit loud when listening from outside the car.
Since the exhaust bubbling sound produced by devices like the bootmod3 is loud enough, you have a wide range of adjustment options, making it easy to tailor the volume and sound quality to your preferences.
　
In Comfort Mode, when driving at a constant speed without accelerating, the B58 engine’s characteristics ensure that the cabin remains quiet enough to hold a conversation.
