The Y-pipe is required for installation and is included in this kit. A separate CB-309A axleback-only listing is available on our site for buyers who already have an aftermarket Y-pipe. This is a muffler delete with no muffler or resonator in the exhaust path.
- Other Q50 owners consistently describe the sound as extremely aggressive. It is not recommended for daily street driving, particularly when paired with aftermarket downpipes. Rev9 designates this product for off-road and competition use only. This product does not ship to California.
Pairs well with:
- aFe Takeda Stage-2 Cold Air Intake Infiniti Q50 / Q60 3.0T (2016-2023) A cold air intake to complement the catback upgrade, pairing improved intake airflow with improved exhaust flow on the VR30 3.0T twin-turbo platform.
- PLM Downpipes Infiniti Q50 / Q60 VR30 (2016-2023) 3" with 200 Cell High Flow Cats Upgraded downpipes to pair upstream of the catback for improved exhaust flow from turbo to tip. Buyers building a full exhaust setup on the VR30 typically combine downpipes with this catback.
Rev9 exhaust systems deliver the most possible power from their minimal bends design. Each exhaust is designed to have the smoothest possible exhaust flow to give you the least possible exhaust restriction, the most power, and the best sound.
Rev9 exhausts are designed to have the best fitment and unless stated otherwise, are a direct bolt on replacement for your factory exhaust system. Mandrel bent piping and TIG welded joints offer the best performance while being long lasting.
