What are the differences between Ultimate Power Version and Standard Version?
The expansion of the diameter leads to a significant improvement on the exhaust flow efficiency, the Ultimate Version's flow area is increased by 24% comparing to the Fi Standard Version Supra exhaust.
To meet the demands of owners aiming for higher horsepower and increased turbo boost, the Ultimate version exhaust system features expanded diameters throughout the entire pipeline. The maximum diameter of the downpipes has been increased from 101mm to 114mm, front pipes from 80mm to 89mm, and axle-back section from 63mm to 70mm. The expansion of the diameter leads to a significant improvement on the exhaust flow efficiency, the Ultimate Version’s (A1 = π * (D/2)^2) flow area is increased by 24% comparing to the Fi Standard Version (A2 = A1 = π * (D/2)^2) Supra exhaust. Beyond diameter expansion, the air flow path around the valve section underwent a redesign. The Ultimate Power Version muffler also has seen reduction in size and now air flow pathway when valves are open is more straight creating a more direct flow and allowing majority of the air flow to bypass the muffler for maximum performance enhancement.
