You're going to need a lot of torque and/or impact. You can buy small electric/battery impacts for pretty cheap nowadays - can be well worth the cost just in reduced frustration levels.  Or use a long-handled wrench.
Applying heat can help but do NOT use an open flame under your car. Even a hair dryer can ignite gas fumes.
Good luck. |
You take all the fun out of things. Sometimes, the flame wrench is the only way to go.
Impact gun, no-no on exhaust. Kiss an O2 sensor or 2 good-bye.
