1978-88 3 GM G-Body Non SS Crossmember Back w/ Xpipe Exhaust System Race Pro Mufflers

Pypes Race Pro dual exhaust systems are designed for increased performance, mileage, and a throaty exhaust tone. They feature mandrel-bent, 16-gauge stainless steel tubing and Race Pro mufflers. Race Pro mufflers offer excellent flow with a straight-through design. The sound profile is subtle at idle and low RPMs, becoming aggressive under acceleration. This is achieved by a stainless mesh around a perforated internal tube, filled with basalt insulation. This 3-inch crossmember-back exhaust system with an X-pipe and Race Pro mufflers is made from 409 stainless steel, and includes EPA compliant catalytic converters (304 grade SS, ceramic substrate, 2.5-inch slip fit, 11-inch length, 4-inch diameter, O2 bung equipped), clamps, and hangers. Designed for enhanced performance, horsepower, and improved gas mileage. Features smooth, seam-coated, 16 gauge, mandrel-bent pipes for maximum exhaust gas flow. Stainless construction resists corrosion.
