• The ISR Single Exit Exhaust Kit: Obviously, this is the star of the show! Make sure you've got the correct kit specifically designed for your G37 sedan.
• Tools:
  • Jack and Jack Stands: Safety first, my friends! You'll need a way to safely lift and secure your car.
  • Wheel Chocks: Extra safety is always a good idea.
  • Wrench Set: A good set of wrenches, including metric sizes, is crucial.
  • Socket Set: Same deal as the wrenches, make sure you have a good metric socket set.
  • PB Blaster (Penetrating Oil): Trust me, you'll thank me later. Rust can be a pain.
  • Gloves: Protect those hands!
  • Safety Glasses: Gotta protect those peepers.
  • Torque Wrench: For tightening everything to the correct specs.
  • WD-40: For lubricating and making things easier to slide.
  • Optional: Impact Wrench (can speed things up), Exhaust Hanger Removal Tool (makes life easier).
• Supplies:
  • Anti-Seize Lubricant: To prevent future corrosion and make things easier down the line.

Make sure you have all these items ready before you even think about starting the ISR single exit install on your G37 sedan. Double-check everything to avoid any mid-project runs to the store. Safety first, and preparation is key!

Detailed Tool Breakdown

Let's break down the tools a bit further. The quality of your tools can really impact how smooth the ISR single exit install goes. Investing in decent tools is a wise move, especially if you plan on doing more work on your car in the future. Here's a more detailed look:

• Jack and Jack Stands: A sturdy jack and a set of jack stands are non-negotiable for safety. Make sure your jack has a good lift capacity for your G37, and always use jack stands when working under the car. Never, ever rely solely on the jack to hold the car up.
• Wrench and Socket Sets: A comprehensive set that includes both standard and deep sockets will be your best friend. Look for quality sets that won't strip bolts. Metric sizes are what you need for this project.
• Penetrating Oil (PB Blaster): This stuff is a lifesaver, especially if your car has seen some miles. Spray it on any rusty bolts or connections a good while before you start working on the G37 sedan ISR single exit install. It'll make those stubborn bolts much easier to remove.
• Torque Wrench: A torque wrench is critical for tightening bolts to the manufacturer's specifications. Overtightening can damage components, while undertightening can lead to leaks or even parts falling off. Make sure your torque wrench is accurate and calibrated.
• Exhaust Hanger Removal Tool: This handy little tool makes removing the rubber exhaust hangers a whole lot easier. You can try using a screwdriver or pry bar, but the tool is designed specifically for this purpose and will save you a lot of frustration.
• Gloves and Safety Glasses: These are non-negotiable safety items. Protect your hands and eyes from dirt, debris, and potential injury.

Having the right tools is half the battle won when tackling the ISR single exit install for your G37 sedan. Don't skimp on quality, and always prioritize safety.

Step-by-Step G37 Sedan ISR Single Exit Exhaust Installation

Alright, now for the fun part: the actual G37 sedan ISR single exit install! Follow these steps closely, and you'll be enjoying that sweet exhaust note in no time. Remember to take your time and don't force anything.

1. Safety First:
   • Park your car on a level surface.
   • Engage the parking brake.
   • Chock the rear wheels.
   • Put on your safety glasses and gloves.
2. Lift the Car:
   • Locate the correct jacking points for your G37 sedan (refer to your owner's manual if you're unsure).
   • Use the jack to lift the front of the car and place it on jack stands.
   • Repeat this process for the rear of the car.
   • Double-check that the car is stable before proceeding.
3. Prepare for Removal:
   • Spray all the exhaust bolts and connections with PB Blaster. Let it sit for at least 15-30 minutes, or even longer if the bolts are rusty. This is crucial for a successful G37 sedan ISR single exit install.
4. Remove the Old Exhaust:
   • Locate the exhaust hangers (rubber mounts) that hold the stock exhaust in place. Use the exhaust hanger removal tool or a pry bar to carefully remove the hangers.
   • Unbolt the exhaust from the catalytic converters (or test pipes, if you have them). Be careful not to round off the bolt heads.
   • If the bolts are stubborn, apply more PB Blaster and let it soak for a bit longer. You might need to use an impact wrench to break them loose.
   • Once the bolts are loose, carefully lower and remove the stock exhaust system. This can be a bit tricky because the system is usually in one or two pieces. Take your time and be patient.
5. Install the ISR Single Exit Exhaust:
   • Assemble the ISR exhaust according to the instructions provided with the kit. Usually, this involves connecting the mid-pipe to the catalytic converters or test pipes, then connecting the muffler to the mid-pipe.
   • Hang the new exhaust using the provided exhaust hangers. Make sure the hangers are securely attached.
   • Align the exhaust and tighten all the bolts. Start by hand-tightening, then use the torque wrench to tighten them to the manufacturer's specifications. Don't forget the anti-seize on the threads!
   • Double-check all connections to ensure there are no leaks.
6. Final Checks and Lowering the Car:
   • Inspect the entire exhaust system for any leaks or obstructions.
   • Make sure the exhaust is clear of any other components, such as the driveshaft or fuel lines.
   • Carefully lower the car back to the ground.
7. Start the Engine and Enjoy!
   • Start the engine and listen for any leaks or unusual noises.
   • Take your G37 sedan for a test drive and enjoy the new sound and performance! You've successfully completed the G37 sedan ISR single exit install!

Detailed Installation Steps: Removing the Stock Exhaust

Removing the stock exhaust is a crucial part of the G37 sedan ISR single exit install process. It's often the most challenging part, as the stock exhaust system can be stubborn, especially if the car has been exposed to the elements. Here's a more detailed breakdown:

• Accessing the Bolts: The exhaust bolts are usually located where the exhaust connects to the catalytic converters or test pipes. You might need to remove a heat shield to access them, which usually involves removing a few bolts. Be careful not to lose any of these bolts, as you'll need them later.
• The PB Blaster Advantage: Generously apply PB Blaster to the exhaust bolts and let it sit. The longer it soaks, the better. Consider applying the PB Blaster the day before you plan on doing the install. This will give it plenty of time to penetrate the rust and corrosion.
• Dealing with Stubborn Bolts: If the bolts are proving difficult to remove, try these techniques:
  • Impact Wrench: An impact wrench can often break loose stubborn bolts that a regular wrench can't handle. Use the impact wrench on a low setting to avoid stripping the bolt heads.
  • Heat: If you have access to a torch, you can heat the bolts to help break them free. Be extremely careful when using a torch, and always have a fire extinguisher nearby.
  • Bolt Extractors: If you strip a bolt head, you might need to use a bolt extractor to remove it. These tools are designed to grip the outside of the bolt and allow you to turn it.
• Removing the Hangers: The rubber exhaust hangers can sometimes be tricky to remove. Lubricating them with WD-40 can make them slide off more easily. The exhaust hanger removal tool is designed to make this task much easier.
• Lowering the Exhaust: Once the bolts are loose and the hangers are removed, you can lower the stock exhaust. This might require some wiggling and maneuvering, especially if the exhaust is in one piece. Have a friend help you if you need it.

Remember, patience and persistence are key when removing the stock exhaust. Don't get discouraged if you encounter difficulties. The G37 sedan ISR single exit install will be worth it in the end!

Tips and Tricks for a Smooth Install

Alright, you're almost there! Here are some helpful tips and tricks to make the ISR single exit install on your G37 sedan even smoother:

• Preparation is Key: Don't rush into the install. Take your time to gather all the necessary tools and supplies, and read through the instructions before you start. This will save you time and frustration.
• PB Blaster is Your Friend: Seriously, don't underestimate the power of PB Blaster. Apply it generously and let it soak. It's the key to removing those stubborn bolts.
• Take Pictures: Take pictures of each step of the process. This will help you remember how everything goes back together, especially if you get interrupted or take a break.
• Watch Videos: Search YouTube for videos of the G37 sedan ISR single exit install. Watching someone else do the install can be incredibly helpful. You can learn tips and tricks that aren't included in the instructions.
• Don't Overtighten: Tighten all bolts to the manufacturer's specifications using a torque wrench. Overtightening can damage components, and undertightening can lead to leaks.
• Double-Check Everything: After you've installed the exhaust, double-check all connections, bolts, and hangers. Make sure everything is secure and that there are no leaks.
• Listen for Leaks: Once you've started the car, listen carefully for any exhaust leaks. You might hear a hissing or ticking sound. If you hear a leak, tighten the connections or replace the gaskets as needed.
• Get a Friend to Help: Having a friend to help you can make the install much easier, especially when removing and installing the exhaust system. Plus, it's always more fun to work on cars with a buddy!
• Take Your Time: Don't rush the process. Take your time and enjoy the experience. The G37 sedan ISR single exit install is a rewarding project that will transform your car's sound and appearance.

Troubleshooting Common Issues

Even with the best preparation, you might encounter some issues during your G37 sedan ISR single exit install. Here's how to troubleshoot some common problems:

• Stubborn Bolts: As mentioned earlier, rusty or corroded bolts can be a real pain. If PB Blaster doesn't work, try using an impact wrench or heat. If you strip a bolt head, you might need to use a bolt extractor.
• Leaking Exhaust: If you hear an exhaust leak after the install, check all the connections. Make sure all the bolts are tightened to the correct specifications. You might need to replace the gaskets or use exhaust sealant to seal any leaks.
• Exhaust Hitting the Body: Make sure the exhaust system is properly aligned and that it's not hitting any part of the car's body. You might need to adjust the hangers or the exhaust system itself to provide clearance.
• Difficulty Removing the Stock Exhaust: The stock exhaust system can be heavy and awkward to remove. Have a friend help you, and take your time. Don't force anything.
• Misfit Parts: In rare cases, you might encounter a part that doesn't fit properly. Double-check that you have the correct kit for your G37 sedan. If you still have problems, contact the manufacturer for assistance.
