Description

The Stillen 508295 is a performance cat-back exhaust system engineered from durable 304 stainless steel. It features a single-in, dual-out configuration that terminates in a split rear exit, offering a distinct look and sound. The "cat-back" design means it replaces the exhaust system from the catalytic converter to the tailpipe, optimizing exhaust gas flow and sound characteristics. This Stillen exhaust system is specifically designed to fit 2008-2013 Nissan Altima 3.5L Coupe FWD models. It's crucial to confirm fitment before ordering, as Fitment Industries and its partners strive to minimize the risk of incorrect orders. If there are any fitment issues or concerns, reaching out to their customer service team is recommended. Please note that all parts must be returned in new, unused condition with original accessories for approval. Returns initiated due to fitment issues recommended by the sales team may have restocking fees waived, provided the item is in like-new condition.
