The N1 Dual is a hybrid variation of the N1 exhaust. This system incorporates a twin pipe, twin canister design for improved mid-range torque without sacrificing top end power. The twin piping is constructed of mild steel with a titanium particle coating mated to SUS 304 polished stainless steel canisters. Each canister features a polished 90mm (3.54 inch) tip. Robotic TIG welds compliment the hand crafted MIG welds to create on of the most innovative and dynamic exhaust systems on the market.

The N1 Dual concept is A'PEX's interpretation of how each vehicle's exhaust system should have looked and performed right from the factory. Designed with the daily driver in mind, this exhaust series focuses on drawing out mid-range torque and engine response for optimal drivability on the street. The styling is subtle and elegant, but still retains characteristics of its racing origin. The result is an affordable cat-back exhaust system that makes the daily commute more enjoyable.
