THE ULTIMATE NSX MUFFLER
The fusion of the famously high-pitched Ver4 and the all-round acclaimed Ver6.
WIDER SECONDARY SPLIT
The biggest visible changes are a wider secondary split and stronger pulse interference at the merge, with refinements throughout for an even higher pitch. Inside, where no one sees, every joint is carefully welded to prevent needless interference — true craftsmanship.
MAIN SILENCER
The basic structure is inherited from Ver1, but the internal materials and design are all new, making it more torque-rich than Ver6. The result of years of research: an ultra-high-pitched muffler on a level entirely its own.
LEFT/RIGHT SPLIT
The flow is split cleanly to the left and right into matching 50 mm paths, producing a high-pitched voice here too — a technique widely used in Ferrari exhausts. Done carelessly it leaves a hollow-sounding muffler, so overall back-pressure is tuned with years of experience and the sub-silencer running beneath the split.
SUB SILENCER
The difference from Ver6 is obvious at a glance — this is no ordinary small silencer. While the surrounding pipes are 50 mm, this section narrows to 45 mm, building torque while guiding exhaust into the main silencer. Ver7's technology and experience in one part.
TAIL END
Refined here too: instead of a straight design, the 50 mm main pipe splits into a 45 mm Y-pipe and returns to 50 mm at the tips — a unique shape that emphasises the high-pitched sound. Look closely at the welding and it resembles a wind instrument. Of course, it clears the late-model NSX OEM undercover.
STAINLESS MODEL (WEIGHT 13.5 KG)
The core model of the F1 Ver7. Its inner structure was developed specifically so stainless delivers a dry sound — a step behind titanium, yet a high-pitched voice that stands comparison. Among premium-grade NSX mufflers, this series is the No.1 choice of owners.
W-TIP SILENCER
A press-fit silencer that installs without drilling the tail ends. Keep to low rpm while it is fitted. To fix it permanently, drill the tail ends.
