The Apexi N1 Muffler series has evolved once again! The new Apexi N1 ExTi (Expert Titanium) offers all the performance and quality of Apexi's race proven N1 Exhaust systems plus the incorporation of an ultra light weight titanium N1 ExTi muffler section.
For years, the Apexi N1 Titan has only been available to Apexi's customers in Japan; Until now A'PEX USA are very pleased to be able to offer this muffler to the US tuning market under the N1 ExTi name.
The Apexi N1 ExTi exhaust system utilizes full stainless steel piping mated to an immaculately constructed Titanium N1 Muffler.
The N1 ExTi muffler section features a full titanium canister which discharges through an adjustable length 115mm super heated (burnt) titanium tip.
The 5 step adjustment range of the finisher tip is designed to allow users with aero kits the ability to extend or retract the tip to meet the dimensions of the rear bumper.
The Apexi N1 ExTi catback exhaust system stands as a true lightweight version of the N1 exhaust, successfully blending form with function.
