Install an ISR Y-Pipe on Your Nissan 370Z for More Power

Improving Your 370Z's Performance With an ISR Y-Pipe

The Nissan 370Z is a legendary sports car that has been thrilling drivers since its debut back in 2008. Over 14 years later, enthusiasts are still finding ways to extract even more power and enjoyment out this rear-wheel drive coupe. One popular modification is installing an aftermarket y-pipe to help maximize gains from other bolt-on upgrades.

What is a Y-Pipe?

A y-pipe refers to the section of the exhaust system that branches off from the single exhaust manifold into a dual/split rear section. Replacing the factory y-pipe with an aftermarket unit that has larger piping and less restrictive bends can allow for better exhaust flow.

The ISR Performance y-pipe is a high-quality option made from T304 stainless steel and mandrel bent for smooth exhaust transitions. This y-pipe is designed as a direct bolt-on upgrade for the 370Z to work seamlessly with the stock components or aftermarket headers and mid-pipes.

Benefits of Installing an Aftermarket Y-Pipe

Here are some of the main benefits you can expect from installing an ISR y-pipe on your Nissan 370Z:

• Increased horsepower and torque output - By reducing exhaust backpressure, the engine can breathe better and produce more power across the entire RPM range.
• Improved throttle response - Lower restriction leads to faster spool up from the turbochargers and a more linear powerband.
• Aggressive exhaust note - The large diameter piping and optimized bends give the exhaust tone an aggressive pitch under hard acceleration.
• CARB-compliance - The ISR y-pipe maintains CARB compliance for street legality in California and states with similar emissions regulations.
• Corrosion resistance - The T304 stainless steel construction resists corrosion and cracking from prolonged exposure to hot exhaust gases.
• Easy, bolt-on installation - No cutting or welding is required. The ISR y-pipe simply bolts up to the stock exhaust manifold outlet and mid-pipe inlet.

Installing an Aftermarket Y-Pipe

Thanks to the bolt-on design, installing an ISR Performance y-pipe takes just a couple of hours in your own garage with some simple hand tools. Here is an overview of the installation process:

1. Lift up the vehicle safely using jacks and jack stands.
2. Loosen the band clamps connecting the stock y-pipe to the mid-pipe and catalytic converters.
3. Remove the nuts securing the flanges at both ends of the factory y-pipe to separate it from the exhaust system.
4. Transfer any oxygen sensors from the factory y-pipe to the ISR y-pipe.
5. Slot the ISR y-pipe flanges into place and reinstall the nuts to secure it hand-tight.
6. Reconnect the mid-pipe using the band clamps.
7. Lower vehicle, start the engine, and check for any leaks.
8. Fully tighten down the nuts and clamps once heated up to specification.

And that's it! You now have an upgraded high-flow y-pipe ready to help your 370Z maximize the performance gains from supporting mods.

Pairing With Other Bolt-On Upgrades

For the best results, an aftermarket y-pipe works best along with these other common bolton upgrades for the Nissan 370Z:

• Cold air intakes - High flowing intakes force more air into the engine to take advantage of the improved exhaust flow.
• Headers - Aftermarket headers further remove restrictions for spent gases to escape.
• Tune - A professional tune helps tailor the air/fuel mapping and ignition timing to match the new hardware.
• Mid-pipe - An aftermarket mid-pipe continues the exhaust diameter gains towards the rear.
• Catback exhaust - Large diameter catbacks allow the upgrades upfront to realize their full potential.

Supporting intake, header, tune and exhaust changes with an ISR y-pipe leads to huge gains in horsepower and torque. Expect gains of 15-20 WHP or more from this round of sensible bolt-on modifications.

Maintenance Tips

The ISR y-pipe is built to last from high grade stainless steel. But here are some tips to help it last:

• Periodically check clamps and nuts for tightness.
• Clean the pipes to prevent dirt/debris buildup.
• Remove excess moisture in winter climates when parked.
• Be cautious over rough roads or steep driveway transitions.

Following these care tips will ensure your ISR y-pipe stays leak-free while delivering huge performance gains for years to come!

FAQs

Will leaving my stock y-pipe limit performance gains from other mods?

Yes, the restrictive factory y-pipe can become a bottleneck for increased airflow even with supporting mods like intakes, headers, tunes, etc. Upgrading to an ISR y-pipe allows your 370Z to take full advantage of those other bolt-on changes.

What tune is required after installing an ISR y-pipe?

We recommend getting a professional dyno tune after installing an ISR y-pipe and supporting mods. This custom tuning helps optimize the more freely-flowing exhaust and intake changes for strong, reliable power gains.

Will an aftermarket y-pipe cause my 370Z to fail emissions testing?

No, the ISR y-pipe is engineered to maintain CARB compliance. Emissions equipment like the catalyst converters are unaffected, so vehicles pass smog testing as normal.

Is welding or fabrication needed to install a 370Z ISR y-pipe?

Nope! The ISR y-pipe bolts up the factory exhaust manifolds and mid-pipe using the stock gasket surfaces. No special tools beyond basic hand tools are required for DIY installation.

Should I replace my oxygen sensors when I install the y-pipe?

Not necessarily. As long as the O2 sensors are in good working condition, they can typically be transferred over and reused from the factory y-pipe to the ISR unit during installation.
