Description

The STILLEN axle-back exhaust system is a stainless steel performance upgrade engineered specifically for 2016-2018 Nissan Altima sedans with 2.5L and 3.5L engines. It features a dual-exit, split rear design with a natural finish, utilizing a muffler to enhance both the exhaust note and vehicle performance compared to the factory system. Please note that this product is not compatible with models outside of the specified 2016-2018 year range or configurations other than the standard sedan. Installation should be performed with care to ensure proper alignment of the split rear exits. As this is an axle-back system, it replaces the factory components from the rear axle to the exhaust tips.
