Exhaust Pipe Coupler

Our couplers can be used to connect the "single" end of a Y-Pipe to a muffler. The couplers are short pieces of pipe (approximately 6" long) that slip-fit inside of mufflers as well as the "single" side of the Y-Pipe.

Made in America.

How Exhaust Sizes Work (I.D. and O.D.)

In the exhaust industry, this is the standard for sizing:

• Exhaust pipes (including our couplers) are measured from outside wall to outside wall ("Outside Diameter"/"O.D.").
• Exhaust components (such as mufflers, Y-Pipes, resonators, and catalytic converters) are measured from inside wall to inside wall ("Inside Diameter"/"I.D.").
