The A'PEXi N1 Evolution combines all the racing heritage and proven performance of the A'PEXi N1 muffler, but raises the ante by adding light weight, fully polished stainless steel piping. This is, in essence, the "ultimate" version of the N1 exhaust system concept.
New Version: Apexi now offers the N1 Evolution R series exhaust systems as well. These are designed to maximize the power production of your car in a new lightweight stainless steel system. With minimal bends for maximum flow you still get the classic N1 sound with the weight savings and durability of stainless.
Featuring mandrel bent, full stainless steel construction, the N1 Evolution exhaust provides maximum power gains and resistance to rust or other damage caused by the elements. Like the original N1, the N1 Evolution uses the minimum amount of pipe bends to allow for greater exhaust flow. The N1 Evolution was created for Subaru WRX owners who are looking for something one step further than the classic N1 design. Available only for a select amount of vehicles, the A'PEXi N1 Evolution stands as a brilliant testament to exhaust system design.
When needed, a Super Silencer ($49 value) is included to suppress exhaust sound output for street applications.
Notes: The N1 Evolution exhaust has an angled muffler tip, which gives it a very aggressive look. It also features a stainless steel muffler. The free Super Silencer (in select applications) will reduce exhaust noise up to 7 decibels.
