Catalytic converter replacement cost
for a Jeep Wrangler

Replacing the catalytic converter on a Jeep Wrangler involves removing the old, failed unit from the exhaust system and installing a new one to restore emissions compliance and engine performance. The cost is primarily driven by the high price of the converter itself, which contains precious metals, and the labour intensity, which varies significantly between the more accessible 4-cylinder models and the V6 or V8 configurations.

Cost breakdown

Parts: ~$800-$2500 / Labour: ~$400-$1000

What affects the price

Engine size and configuration (4-cylinder vs. V6/V8) affecting part cost and labour complexity
Quality and origin of the replacement part (OEM, aftermarket, or California-compliant)
Condition of exhaust hardware (rust, seized bolts) increasing labour time

Can you do it yourself?

Possible with skill — Requires good mechanical ability, proper jacking/security, penetrating oil for rusty bolts, and torque wrench for reinstallation. Access can be tight, especially on 4WD models.

Tips before you pay

Confirm if you need a CARB-compliant (California Air Resources Board) converter, as they are more expensive but legally required in many states.
Consider replacing oxygen sensors at the same time if they are old, as a failing cat can contaminate them.
Inspect the entire exhaust system for leaks or damage while the converter is off, as this is the ideal time for related repairs.
