IMPORTANT QR25DE FITMENT NOTICE

This header is designed for compatible Nissan 2.5L QR25DE four-cylinder applications. Vehicle exhaust configurations can vary by year, chassis, trim, emissions equipment and market. Verify the flange pattern, O2 sensor configuration, EGR requirements, outlet dimensions and vehicle application before ordering.

16-Gauge Stainless Steel Construction

A performance exhaust header must operate directly against high-temperature exhaust gases. This header uses 16-gauge stainless steel construction with approximately 1.5mm wall thickness for a durable performance-oriented exhaust component.

The mirror-polished exterior finish gives the header a clean performance appearance, while the 0.40-inch flange provides a substantial mounting surface at the cylinder head.

QR25DE Performance Exhaust Upgrade

The QR25DE powered a range of popular Nissan performance and street applications, including the Altima 2.5 and Sentra SE-R / Spec V. A performance shorty header replaces the factory-style exhaust manifold with a runner and collector configuration designed around improved exhaust flow.

This makes the XS-POWER stainless shorty header an excellent component for enthusiasts building a QR25DE performance exhaust, Sentra Spec V exhaust setup, Sentra SE-R performance build or Nissan Altima 2.5L project.

Package Includes

1 x Stainless Steel QR25DE Shorty Exhaust Header / Manifold

Professional Installation Recommended
