The best price I could find for a toyota exhaust nut. Worked great on my Tacoma. Always use OEM Toyota nuts and studs when replacing exhaust parts. The OEM nuts are heat resistant and will last while locking to the ideal pounds when tightening. Remember to use loctite blue when installing for a more secure bond. Do it right and you won't have to worry about leaks. Exhaust leaks in the Toyota trucks results in problems with efficiency and hurts the MPG.
