Infiniti Q60 Axleback Exhaust: Daily Sound and Fit Notes

Start with the car, not the sound clip

The first decision on a Q60 exhaust upgrade is whether the part is built for your car. The REMARK Infiniti Q60 Axleback Exhaust System is listed for all Q60 models from 2017 to 2022, in both rear-wheel drive and all-wheel drive. That covers the 3.0t cars in that window, but it does not cover every Infiniti. The same listing states plainly that this product does not fit the Q50, so do not treat the two sedans as interchangeable when ordering.

If you are shopping for a q60 3.0t exhaust, this is the compatibility line to verify before anything else. The axleback is a two-piece bolt-on design, which means it replaces the rear section rather than the full system. That keeps the job smaller and the cost lower than a full catback, but it also means the result depends on what is already upstream on your car.

What the Q60 axleback is built from

• Axleback - Infiniti Q60 [2017-2022]: Fits all Q60 (2017-2022 - RWD & AWD); does not fit Q50. This is the fitment boundary that decides whether the part belongs on your car at all.

  

• Axleback - Infiniti Q60 [2017-2022]: 2.5-inch, 16-gauge, mandrel-bent T304 stainless steel piping. The piping size and material are the core construction facts behind the daily-driving character.
• Axleback - Infiniti Q60 [2017-2022]: 4.5-inch slant-style tips, available in stainless or burnt finishes, single or double wall. Tip style is the main visual choice and the one option you select at checkout.
• Axleback - Infiniti Q60 [2017-2022]: Axle Back Exhaust Bolt on 2pc design. A two-piece bolt-on rear section is a simpler install than a full system, but it still needs the correct Q60 application.

What daily sound actually depends on

REMARK describes this as an easy, simple way to bring out the potential of the Q60, with the sporty character the car was engineered for. That is the design intent, not a decibel rating. The supplied information does not include measured sound levels, drone figures, or in-cabin comparisons, so anyone promising you an exact q60 exhaust sound result is going beyond what the catalog states.

What the record does support is the hardware behind the sound: 2.5-inch mandrel-bent T304 piping and a rear-section-only design. An axleback changes the last part of the exhaust path, so it tends to shape the tone and volume at the tail rather than re-engineer the whole system. If you want a milder daily result, the double-wall tip options are the conservative visual choice; if you want the burnt look, that is a finish decision, not a sound one.

Choosing between the tip options

The listing shows several tip configurations. The part numbers below are the ones named in the catalog; confirm the exact variant at checkout.

• Stainless Single Wall (RO-TSQ6-S): A clean stainless finish with a single-wall tip. The simplest look in the range.
• Stainless Double Wall (RO-TSQ6-D): Stainless finish with a double-wall tip. A more finished edge look if you prefer a subtler tail.
• Burnt Single Wall (RO-TTQ6-S): The burnt finish with a single-wall tip, for owners who want the tail to stand out.
• Burnt Double Wall (RO-TTQ6-D): Burnt finish with a double-wall tip. The most visually aggressive of the listed options.

The order terms you should read before paying

Two supplied notes matter more than any spec sheet. First, the listing states that no returns or exchanges are accepted, so the fitment check is not a formality. Second, the REMARK Limited Warranty is described as eligible for purchases made directly from remark-usa.com, and it excludes taxes and duties on international orders. If you are buying through another channel, confirm the warranty path before you order.

The listing also directs buyers to read the disclaimer before purchasing. That is a short step, but it is the one place where order-specific conditions are set out, so treat it as part of the buying decision rather than paperwork to skip.

A sensible order and install sequence

The catalog does not include a step-by-step installation procedure, so the sequence below is about preparing the order correctly, not a substitute for the manufacturer's instructions.

• Confirm the model year and drivetrain: The system is listed for Q60 2017-2022, RWD and AWD. If your car is a Q50, this part is not for you.
• Pick the tip style: Choose stainless or burnt, single or double wall, and note the matching part number so the order matches what you want.
• Read the disclaimer and warranty terms: No returns or exchanges are accepted, and the limited warranty is tied to direct purchases from remark-usa.com.
• Have the install handled by a qualified shop: The supplied information describes a two-piece bolt-on axleback but does not provide torque specs or a full procedure, so rely on the manufacturer's instructions and a professional installer.
