Y-Pipes: the merge that ties a dual manifold into one pipe

On a V6 or V8, each cylinder bank feeds its own downpipe, and a y-pipe is the section that merges those two flows into a single exhaust pipe before the muffler. Swapping the factory y-pipe is a common early exhaust job because the stock unit is often a restrictive point in the system. A mandrel-formed replacement keeps the pipe cross-section consistent through the merge, and some of the y-pipes stocked here integrate a catalytic converter so you keep the cat in the same section you're replacing.

What ThreePiece stocks in y-pipes

There are 11 y-pipes in stock right now, priced from $132 to $921. That's the current range for what's on the shelf, not a fixed price. The spread covers 6 brands: aFe leads the sample with four listings, followed by ISR Performance with three, and single entries from Magnaflow, Revel, Roush and Turbo XS.

Seven of the eleven carry vehicle fitment data, spanning model years 2002 through 2020. The makes covered include Toyota, Jeep, Infiniti, Nissan, Ford and Subaru, with top vehicles being the Toyota Tacoma, Jeep Wrangler, Infiniti G25, Ford Mustang and Subaru WRX. Concrete examples: the aFe Twisted Steel Y-Pipe with cat for the 16-20 Tacoma 3.5L (4WD only) sits at the top of the range, the Revel Y-Pipe for the 11-13 Infiniti G25 sedan RWD lands in the middle, and the Roush Y-Pipe for the 2015-2019 Mustang EcoBoost 2.3L is one of the lower-priced options.

How to choose

The first split is with or without a catalytic converter. A y-pipe that includes a cat, like the aFe Twisted Steel units for the Tacoma, replaces the stock section wholesale and costs more. A cat-less y-pipe, like the ISR Performance Y-Pipe for the 370Z / G37 or the ISR Q50 / Q60 3.0T unit, is a simpler pipe at a lower price. The second split is drivetrain-specific: several of these listings are model, engine and drivetrain locked, such as 4WD-only or Non-AWD X models, so match your exact configuration before ordering.

What else you may need

A y-pipe is one section of the system. Pair it with a cat-back exhaust or an axle-back system for the rest of the run, and check exhaust flanges and exhaust pipes if you're piecing a system together. If you're replacing a cat separately, see catalytic converters. Browse the full Exhaust section for headers, mufflers and tips.

Fitment and ordering

Confirm the exact year, engine and drivetrain against the listing before you buy. For fitment help, call 813-535-5801 or reach us through contact us. All orders ship free, and Affirm financing is available.
