Show original supplier description
The Extreme Online Store axle-back exhaust system is engineered to enhance the sound and performance of your 2022-Present Subaru WRX. This system replaces the exhaust components from the rear axle to the tips, featuring a muffler dual delete design for increased exhaust flow and a more aggressive tone. Constructed from durable T-304 stainless steel, this axle-back exhaust boasts a 2.5-inch pipe diameter and 4-inch diameter exhaust tips. The tips are single-walled, round, and angle-cut, available with either an anodized silver finish or chrome tips (specific variant may vary). This design aims to improve vehicle sound and appearance without requiring modifications to the exhaust system ahead of the rear axle. Professional installation is highly recommended for this exhaust system. Please note that the warranty does not cover damage resulting from improper installation, misuse, racing or track usage, off-road driving, or accidents. Normal wear and tear, fading, and post-purchase modifications are also excluded from warranty coverage.
