Description

This exhaust system offers a great combination of features for those seeking hardcore exhaust systems. It features an inner silencer system and reductions in piping with a straight-through design for maximum exhaust flow and power output. It has a beautiful mirror finish with a modern day titan gradation tail, TIG welded via the shokunin, providing a look and style to match the performance. Quality construction and next-level design maintain a solid sports sound without being raspy or overly loud.
