Show original supplier description
The PaceSetter Exhaust Header is a performance-focused replacement manifold featuring a 4-2-1 design, 1-5/8 inch mandrel-bent tubing, and a 2-inch flanged collector. Constructed from mild steel with thick, surface-ground steel flanges, it is built to replace factory restrictive manifolds. The unit includes an extension to facilitate connection to the factory exhaust system and features integrated hook-ups to maintain compatibility with factory smog and engine management sensors. Professional installation is strongly recommended for this component, and users should be aware that fabrication may be required during the fitting process to ensure proper clearance and alignment. The header is designed specifically for the 1991-1999 Nissan Sentra SE-R and Infiniti G20 equipped with the 2.0L SR20DE engine. Please note this header is not compatible with models equipped with the 1.6L engine; it does not fit the 1998 Sentra SE. Header mounting bolts are not included with the package.
