60mm piping with a 115mm Tip. This exhaust differs from the N1 in that it is a 100% stainless steel exhaust.
The GT Spec is the ultimate in high power exhaust systems. Previously available only for GT class vehicles, A'PEX has raised the ante by expanding their lineup to include the 1.6-2.0 liter vehicles. The GT System is a FULLY polished stainless steel exhaust. An A'PEX Silvencer is included to lower sound output for street applications. By using even lighter SUS 304 stainless steel piping to save weight, the new GT Series muffler stands as the benchmark of power, craftsmanship, and design. Each muffler incorporates immaculate robotic TIG welds in addition to hand crafted welding.
