A'PEXi N1 Cat-back Exhaust WRX/ STi 02+: FREE SHIPPING
N1 Cat-Back Exhaust System with 115mm Tip
Note: 65mm-65mm-80mm Piping Diameter
The A'pex Integration N1 exhaust system is one of the most recognizable exhausts in the import scene. It was the first angled muffler to utilize a silencer and megaphone style piping. The piping utilizes a mild steel titanium particle powder coating to flow expended exhaust gasses out through a polished SUS 304 stainless steel canister. The N1 also uses a large noticeable tip with silencer. This exhaust system has been put to the test in virtually every tuning magazine. These conclusive results have proven the N1 to be one of the most reliable, powerful, and cost effective mufflers on the market. The robotic TIG welding separates the N1 from its cheap imitators. The N1 has been used in drag, circuit, rally, and street events. Since this exhaust was created through the direct participation in the N1 Endurance Series in Japan, there is no mistaking its potential. The simple yet effective design will stand the test of time. This is truly the one, the original!
