Axle Back Exhaust for Infiniti Q60 (2017-2022) 2.0L 3.0L

High-Flow Axle Back Exhaust for 2017-2022 Infiniti Q60 (CV37)

What it Does: The Axle Back Exhaust replaces the restrictive stock rear mufflers on the 2017-2022 Infiniti Q60 to eliminate exhaust backpressure, shed parasitic weight, and deliver an aggressive exhaust acoustic profile.

The Stock Infiniti Q60 Exhaust Restriction

The factory rear silencers on the CV37 chassis utilize restrictive multi-chambered baffles and internal resonators engineered primarily for cabin isolation. While quiet, these chambers generate high backpressure downstream of the catalytic converters, stifling exhaust gas velocity and dampening turbo spool dynamics on both the VR30DDTT twin-turbo V6 and M274 2.0L platforms. Furthermore, the massive stamped-steel OEM muffler assemblies burden the rear subframe with excessive dead weight.

The Engineering Solution

Fabricated from heavy-duty stainless steel, this straight-through muffler delete configuration eliminates internal baffles to establish an unobstructed flow path for expanding exhaust gasses. Smooth mandrel-bent 2.25-inch OD tubing maintains high gas velocity to promote exhaust scavenging without inducing drone. Thick 3/8-inch CNC-machined flanges with precision TIG welds ensure an airtight, warp-resistant seal against factory intermediate pipes. The system terminates in dual 4.0-inch double-walled burnt-finish tips designed to withstand thermal expansion and resist heat discoloration.

Frequently Asked Questions

Does this fit the CV37 Q60?

Yes, this is a direct fit for the 2017-2022 Infiniti Q60 equipped with the VR30DDTT and M274 engine platforms.

Will this axle-back system trigger a Check Engine Light (CEL)?

No, this system installs entirely downstream of the secondary catalytic converters and factory oxygen sensors, preserving OEM emissions compliance and preventing diagnostic fault codes.

The Infiniti Acoustic Standard

Engineered for high-output Japanese sports coupes, this axle-back setup reveals the crisp, resonant exhaust note of the VR30DDTT platform while substantially dropping rear-chassis curb weight.
