Infiniti Q50 Y-Pipe vs Midpipe: Which Upgrade First?

Deciding between a Y-pipe and midpipe for your Infiniti Q50? This comparison breaks down the performance and sound trade-offs to help you choose the right upgrade order.

Quick answer

Start with the Y-pipe for a noticeable drop in backpressure and a deeper exhaust note, then add the midpipe if you want more volume and a complete catback system.

How the Y-pipe and midpipe differ in function

The Y-pipe sits right after the downpipes and merges the two exhaust streams into one. Reducing restriction at this point improves flow from the turbos, which can lower spool time and add a deeper tone without making the car much louder.

The midpipe connects the Y-pipe to the axleback section. Swapping it out increases overall exhaust volume and sharpens the sound, but the performance gain is smaller than the Y-pipe unless you also upgrade the sections before and after it.

Trade-offs at a glance

Y-pipe first: Installing the Y-pipe before the midpipe reduces backpressure from the merge point, which can improve turbo response and deepen the exhaust note. It works as a standalone upgrade without other exhaust parts.
Midpipe first: Adding a midpipe to a stock Y-pipe increases volume and sharpens the tone, but the flow restriction at the stock Y-pipe limits potential power gains. You'll hear more sound without matching performance.
Both as a system: Pairing the Y-pipe and midpipe with a REMARK axleback creates a full catback system. This combination maximizes flow and sound control, but costs more upfront and requires more installation work. If your goal is a complete catback system, buying both components together saves on shipping and ensures seamless fitment.

Product facts

Y-Pipe Kit - Infiniti Q50 [2016-2024]: The Y-pipe bolts directly to the downpipes and includes flex couplers on each leg to reduce stress on the merge collector. Flex couplers help the system handle engine movement without cracking, making this a durable first upgrade for the Q50 3.0T.

Midpipe Kit - Infiniti Q50 2016-2024 RWD / AWD: The midpipe kit directly bolts to the REMARK axleback system and uses 2.5" mandrel-bent piping. Mandrel bends keep internal diameter consistent, preserving gas velocity and scavenging for a cleaner sound and better throttle response.

Which upgrade fits your build?

Best for

Drivers who want improved throttle response and a deeper tone without a major volume increase
Those planning a future catback system and want to spread out the cost

Not ideal for

Anyone who wants maximum volume right away without touching the Y-pipe
Owners who are satisfied with the stock sound and only want a small change
