For 800-1400 horsepower range applications, HKS now offers the Racing Muffler system.
Constructed of 102mm diameter, high-luster polished SUS304 stainless steel piping and a 170mm Titanium muffler assembly, the Racing Muffler is the lightest system (40% lighter than the race inspired Hi-Power Exhaust system) and the highest flowing exhaust system HKS offers.
The muffler utilizes a slip-on/latch design that mates polished stainless steel piping and a lightweight titanium Muffler assembly.
All Racing Muffler systems incorporate a 115mm-diameter tip and include a removable inner silencer for pit area use. HKS TITANIUM EXHAUST (4 inch) SUPRA 2JZGTE JZA80
