The DES104 LS Swap Exhaust System is a complete, direct-fit exhaust solution for 1970–1981 GM F-Body Camaro and Firebird models using an LS engine and Doug’s swap headers. Constructed with heavy-duty 3 in. mandrel-bent 304 stainless steel tubing, the system delivers maximum exhaust flow and long-term durability. The kit includes all necessary components; X-pipe, mufflers, over-axle and tail pipes, clamps, hangers, and installation hardware, allowing for a full bolt-on installation when used with Doug’s headers, motor-mount brackets, and transmission crossmember.

Doug's Headers DES104 GM LS Engine Swap Exhaust System Notes:

• Requires Doug’s LS Swap Headers, motor mounts & transmission crossmember for proper fitment; not compatible with unrelated headers or stock manifolds.
• Catalytic converters are not included; for classic or pre-emissions vehicles only (not CARB compliant for modern emission-controlled cars).
• Installation requires removal of existing exhaust and mounting hardware; full swap exhaust install recommended on a lift or rotisserie.
• Verify clearance for brake lines, parking brake cables and rear axle components before tightening clamps.
• Because this is a full exhaust system, expect professional-level fitment and possible need for minor adjustments depending on chassis modifications or suspension setup.
