    Looking for a true dual exhaust upgrade for your G8, Caprice PPV, or SS Sedan? Speed Engineering's true dual exhaust system is built from 3" mandrel bent 304 natural stainless steel with a true dual X-pipe design, insulated blow-through mufflers, and dual 3.5" rear exit tips included. One of the standout features of this system is its versatility — it works with both the factory exhaust manifolds and cats or Speed Engineering longtube headers, giving you flexibility whether you're building in stages or all at once.

    ⚠️ Important Installation Notes:

    • Cutting on the factory exhaust is required for cat-back installation
    • For longtube header applications: Speed Engineering's X-pipe kit is required for proper connection — sold separately
    • Caprice PPV applications: Modifications are required. Tips will need to be extended approximately 6" to align with the factory bumper cutout

    Features:

    • 3" Mandrel Bent Tubing — Consistent diameter throughout for maximum exhaust flow
    • True Dual X-Pipe Design — Balances exhaust pulses between banks for improved tone and mid-range power
    • Works with Stock Factory Manifolds and Catalytic Converters — Direct bolt-on compatible
    • Works with Speed Engineering Longtube Headers — Compatible when used with Speed Engineering X-pipe kit
    • Insulated Blow-Through Mufflers — 3" inlet / 2.5" dual outlet per muffler
    • Dual Rear Exit Design
    • Dual 3.5" Exhaust Tips Included
    • 3" Stainless Band Clamps Included
    • 304 Natural Stainless Steel Construction — Corrosion resistant, heat tolerant, and built to last
