~(60 lbs. 60X14X14)~ 1975-80 Corvette C3 2.5IN Crossmember Back w/ Xpipe Exhaust System SP

Pypes Exhaust Systems are designed for enhanced performance, improved gas mileage, and increased horsepower due to maximum exhaust gas flow from 16 gauge, mandrel-bent, stainless steel pipe. The stainless construction resists corrosion, extending system life. Includes stainless X-pipe, tailpipes, clamps, and hangers. Installation can be done at home (some cutting may be required). Use DCC10 SB Manifold downpipes to complete. 1979-1980 owners may need a dual hump crossmember; when using headers, connections must be completed between headers and the system. Features EPA compliant catalytic converters made from 304 grade stainless steel with a ceramic substrate, 2.5 inch slip-fit design, 11 inch length, and 4 inch diameter. "Relief notches" in the X-pipe clear the emergency brake mechanism.
