Product Description

The MBRP S47123CF is a 3-inch Armor Pro axle-back exhaust system engineered specifically for the 2021-2026 Hyundai Elantra N-Line equipped with the 1.6L turbocharged four-cylinder engine. As an axle-back system, it replaces the factory muffler and rear exhaust section from the rear axle back, making it one of the most straightforward performance upgrades available for the N-Line. MBRP's Street Profile tuning is designed to deliver a noticeably deeper and more aggressive tone under hard acceleration while remaining composed and non-droning during everyday commuting and highway driving - a balance purpose-built for daily-driven sport compacts.

Constructed entirely from T304 stainless steel, the Armor Pro series represents MBRP's highest durability tier, built to withstand rust, road salt, and extreme weather without degradation over time. The system pairs that structural integrity with a striking carbon fiber dual-wall angle-cut tip featuring dual 4-inch outlets - an outer shell of genuine carbon fiber wrapping a mirror-polished T304 stainless steel inner sleeve. The single dual rear exit layout replaces the factory single outlet and transforms the rear bumper into a performance-oriented focal point that looks factory-intentional on the N-Line's sport-tuned body.

Installation is a direct bolt-on process using the factory hanger locations - no cutting, welding, or specialized tools required. This system is compatible exclusively with the N-Line trim powered by the 1.6L turbo engine and is not designed to fit the standard, SE, SEL, or Limited Elantra variants, which use different exhaust routing and rear bumper configurations. The S47123CF is covered by MBRP's Lifetime Warranty and is the ideal upgrade for Elantra N-Line owners seeking a genuine performance sound improvement with a race-inspired visual upgrade that stands up to years of daily use.
