Stainless Steel Manifold Header Exhaust For 1991-1999 Jeep Wrangler YJ TJ Cherokee XJ Grand Cherokee ZJ 4.0L 6CYL Sliver

Stock exhaust manifolds on older Jeeps are often cast iron and restrictive, limiting airflow and performance. Upgrading to a stainless steel header manifold:

✔ Improves exhaust gas flow
✔ Increases throttle response
✔ Reduces engine backpressure
✔ Enhances torque throughout the RPM range
✔ Adds a performance exhaust sound
