Y Pipes

Y-Pipes are a very useful exhaust component. They are useful for creating "dual out" or "dual in" muffler setups, useful for creating "dual back" exhaust, and much more.

We carry Y-Pipes in a variety of inlet/outlet sizes. They are available in stainless or aluminized steel, and we offer several extended warranty options.

Shipping is fast and affordable. FREE economy shipping if your cart totals more than $90 USD.

Note: We quality inspect each and every item we carry we by hand in our US facility. Our mufflers are made entirely in the US, but our Y-Pipes are sourced from outside our company and may have origins in other countries. Photos are for representative purposes only.

Couplers

We offer couplers, which 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.

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

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

• Exhaust pipes 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.").

This industry standard allows pipes to slip-fit inside components like mufflers and Y-Pipes. For example, a 3.00" pipe will slip-fit into a 3.00" muffler.

Our couplers are straight pieces of pipe that slip-fit inside our Y-Pipes and mufflers.
