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.
