Product Specifications
370Z and G37 VQ37VHR Y-Pipe Exhaust Section
The Flashark 370Z Y-pipe joins the two sides of the exhaust before the rear section. It replaces the factory-style merge with a polished stainless section and welded flex joints. This Y-pipe is listed for 2009–2016 Nissan 370Z Z34 and selected rear-wheel-drive Infiniti G37 Coupe, Sedan and Convertible models with the 3.7L VQ37VHR V6.
It is the Y-pipe merge section, not a turbo downpipe or a pair of catalytic-converter-replacing test pipes. Select the package you need before checkout; other Style options add different exhaust parts.

Key Features
- Two-into-one exhaust merge: Connects the left and right front exhaust paths to the rear section through a smoother, larger-volume junction than the factory-style pipe.
- Welded flex sections: Allow movement in the exhaust assembly and help reduce stress at the flanges and welds.
- Polished stainless construction: Offers the clean appearance, heat durability and corrosion resistance described for this part.
- 2.5-inch inlets and 3.0-inch outlet: Use these listed dimensions when checking existing front pipes and the downstream mid-pipe.
- Sound and response: The freer-flowing merge is intended to deepen the VQ37 tone and sharpen throttle response; the result depends on test pipes, resonators, mufflers and the rest of the exhaust.
- Build options: The Y-pipe can be paired with compatible headers, test pipes or a cat-back, subject to the selected package and connection checks.
Where This Y-Pipe Sits in the Exhaust
The Y-pipe merges flow from the two front exhaust paths before the mid-pipe and cat-back. The base Y-pipe section does not replace the front catalytic-converter sections. It is intended as a direct bolt-on replacement on the listed RWD factory-style layouts; prior exhaust modifications, worn hardware and flange alignment may change the installation work. Professional installation is recommended.
Compared with the quieter factory-style merge, this part is aimed at a more noticeable exhaust character and smoother flow. On a stock-tuned VQ37VHR, the existing product listing estimates 5–8 HP for the Y-pipe alone. For a full exhaust build with test pipes, Y-pipe, cat-back and ECU tune, it estimates 10–15 HP and 5–10 ft-lbs. Results depend on the full setup, tune, engine condition and installation quality.
What Is Included

Check Before Ordering
- Confirm the year, model, engine, RWD drivetrain and current exhaust layout. The listing excludes G37X/G37XS AWD models and 2017–2020 370Z models.
- If you have aftermarket front pipes or test pipes, compare the inlet flange position and listed 2.5-inch connection with your existing system.
- If you have an aftermarket cat-back, compare its mid-pipe inlet with the listed 3.0-inch Y-pipe outlet.
- Factory hardware condition, rust and previous exhaust work can affect fit and installation time.
- The Y-pipe-only option sits after the factory catalytic-converter sections. Some other Style options include catless test pipes that replace those sections. Check the parts in your chosen option and applicable local requirements before ordering.
- The listing describes this product for off-road or track use and does not provide a street-use approval for a specific vehicle or jurisdiction.
