Description

This muffler features a buffed finish and dual slash-cut tailpipes (φ95 x 2 on each side) for a sporty look and enhanced sound. Constructed from durable all-stainless steel, this performance muffler offers a weight savings of 1.8kg compared to the original equipment. It is engineered to reduce airflow back pressure by 16% and is claimed to increase acceleration by 2%, according to STI. The system includes 5 hanger cushions for proper mounting and comes with Subaru Genuine gaskets and self-lock nuts. This axle-back system is a direct fit for the Subaru WRX VB model.
