GT Spec Mufflers are Apex's flagship line of exhaust systems. These
race-bred exhaust systems were engineered to handle extremely
high-horsepower applications. A'PEX is the only company in Japan to own
and operate a 95mm (3.74 inch) mandrel pipe bender at this time. They
proudly incorporate this 95mm piping on select applications to offer
exhaust systems unmatched by any other manufacturer. Pipes for the GT
Series are designed with minimal amount of bends and the canisters
project at an angle like the N-1. The GT Series pipes and canisters are
constructed of polished SUS 304 stainless steel. The 115mm polished tip
give the GT Spec Mufflers an aggressive, yet refined style. GT Spec
Mufflers include the Super Silencer, which can reduce noise levels by
up to 7 decibels.
