Detailed Description

AP Exhaust 8439 is an exhaust pipe flange gasket intended for sealing the connection point between exhaust pipes and mating flanges. The 2-1/2 inch inside diameter and 3-bolt layout help ensure the gasket matches the flange geometry used on select Acura TSX and Honda Accord exhaust systems. For 2003-2007 Honda Accord applications, the fitment note specifies use with an aftermarket catalytic converter, making this gasket relevant for exhaust repair and replacement work where the flange interface must be sealed correctly. AP Exhaust 8439 is a practical replacement choice when servicing exhaust leaks at the flange connection on these vehicles.

• Fitment issues when replacing a flange gasket on a 3-bolt exhaust joint
• Service needs on Acura TSX and Honda Accord exhaust repairs

Installation Notes and Tips

For Honda Accord applications, verify the aftermarket catalytic converter note before ordering or installing.
