The Muffler Comparison with stock muffler

The sound has been tuned to allow you to enjoy the V6 engine sound. The deep bass that exudes presence befitting the Land Cruiser’s class envelops the vehicle, creating a refined and solid sound.
This effectively suppresses interior noise when driving at constant speeds on highways, ensuring comfort even in the rear seats, where noise is particularly noticeable.
In addition to eliminating the unpleasant muffled noise that resonates inside the cabin during normal use, we also paid particular attention to the volume and sound quality during cold starts and idling.

Appearance
We pursue not only performance but also attention to detail.
The main muffler is TIG welded and carefully finished by skilled craftsmen one by one.
Products born from outstanding technology achieve excellent strength and a beautiful finish.

The tailpipe is black coated to enhance the texture, and the silencer has a lustrous polished finish. The large diameter tailpipe matches the bumper line to enhance the rear view of the Land Cruiser, and the black coating gives it a stylish impression.

New tail logo
We have refined the previously used “EXHAUST TECHNOLOGY” to simply express “EXH TECH” together with the HKS logo, creating a logo that conveys technological prowess and sophistication.

●Performance comparison

	Maximum output (kW(PS)/rpm)	Maximum torque (Nm (kgf・m)/rpm)
LTM	294.7(400.8)/5540	589.6(60.2)/3640
Genuine muffler	285.9(388.8)/5440	583.9(59.5)/3560

Power output improves across the entire range above 2500 rpm, allowing the engine to rev smoothly up to the rev limit.
The assembly section of the intermediate pipe has been optimized, and the interior of the main silencer has been changed from a partitioned structure to a straight structure, improving exhaust efficiency and achieving increased power output from 2500 rpm.
When merging onto the highway or overtaking, stepping on the accelerator allows for smooth, stress-free acceleration.

●Performance comparison (when combined with HKS Mastery ECU (42019-AT016))

	Maximum output (kW(PS)/rpm)	Maximum torque (Nm (kgf・m)/rpm)
LTM	307.2(417.8)/5440	654.9(66.8)/2680
Genuine muffler	302.5(411.4)/5100	636.1(64.9)/3560

When combined with the HKS Mastery ECU, the peak power output is increased by approximately 4.2kW. The peak torque is also increased by approximately 18.8Nm, with the maximum difference being a significant 20.6Nm.
In addition to replacing the muffler, tuning it in conjunction with the ECU can further improve output.
