So, you're looking to upgrade your G37 sedan with an ISR single exit exhaust? Awesome choice, guys! A single exit exhaust can seriously transform the sound and look of your ride, giving it a more aggressive and sporty vibe. This guide will walk you through the install process, making it as smooth as possible. We'll cover everything from tools you'll need to the nitty-gritty steps involved. Let's get started!

What You'll Need

Before diving in, it's crucial to gather all the necessary tools and equipment. Trust me; you don't want to be halfway through the installation and realize you're missing something. Here's a comprehensive list to ensure a seamless experience:

  • New ISR Single Exit Exhaust System: Obviously, this is the star of the show! Make sure it's specifically designed for your G37 sedan model year to ensure proper fitment.
  • Socket Set: A good socket set with various sizes is indispensable. Metric sizes will be your best friend here.
  • Wrench Set: Just like the socket set, having a variety of wrench sizes is crucial for tackling different bolts and nuts.
  • Penetrating Oil: This stuff is magic for loosening stubborn or rusted bolts. Spray it on and let it soak for a bit before attempting to remove anything.
  • Jack and Jack Stands: Safety first! You'll need to lift your G37 and secure it with jack stands to work underneath it safely. Never work under a car supported only by a jack.
  • Wheel Chocks: Place these behind the rear wheels to prevent any accidental rolling.
  • Gloves: Protect your hands from grease, grime, and potential cuts.
  • Safety Glasses: Flying debris is no joke. Keep your eyes safe with a good pair of safety glasses.
  • Torque Wrench: Essential for tightening bolts to the manufacturer's specified torque. This prevents over-tightening and potential damage.
  • Hangers Removal Tool (Optional but Recommended): Exhaust hangers can be a pain to remove. This tool makes the job much easier.
  • Patience: Last but not least, bring your patience. Exhaust installs can sometimes be finicky, so take your time and don't rush.

Step-by-Step Installation Guide

Alright, with all your tools ready, let's get down to the actual installation. Follow these steps carefully, and you'll have your new ISR single exit exhaust installed in no time.

1. Prepare Your G37

Start by parking your G37 on a level surface. Engage the parking brake and place wheel chocks behind the rear wheels for added safety. Now, use your jack to lift the car and securely place jack stands under the designated jack points. Make sure the car is stable before proceeding. Safety is paramount, guys! Double-check everything before you start wrenching.

2. Remove the Old Exhaust System

This is where the penetrating oil comes in handy. Locate all the bolts and nuts connecting your old exhaust system to the car. Generously spray them with penetrating oil and let it sit for about 15-20 minutes. This will make removing them much easier. Next, disconnect the exhaust hangers. If you have an exhaust hanger removal tool, now's the time to use it. Otherwise, you can try using a flathead screwdriver or pliers to pry them off. Be careful not to damage the rubber hangers. Once all the hangers and bolts are disconnected, carefully remove the old exhaust system. It might be heavy, so have a friend help you if needed. With the old system out, take a moment to inspect the area for any damage or rust. Clean it up if necessary.

3. Install the ISR Single Exit Exhaust

Now for the fun part! Unpack your new ISR single exit exhaust system and familiarize yourself with all the components. Start by attaching the exhaust to the catalytic converters or mid-pipe using the provided bolts and gaskets. Make sure the gaskets are properly seated to prevent leaks. Hand-tighten the bolts for now. Next, align the exhaust system and connect the hangers to the corresponding mounting points on your car. Again, make sure everything lines up properly before tightening anything down. Once you're satisfied with the alignment, use your torque wrench to tighten all the bolts to the manufacturer's specified torque. This is crucial to prevent leaks and ensure a secure connection. Double-check all the connections and hangers to make sure everything is properly installed.

4. Final Adjustments and Checks

Before lowering your G37, take one last look at the exhaust system. Make sure there's enough clearance between the exhaust and any other components of the car. Adjust the hangers if necessary to achieve proper clearance. Once you're satisfied, carefully lower the car and remove the jack stands. Start the engine and listen for any exhaust leaks. If you hear any leaks, immediately shut off the engine and re-check all the connections. Tighten any loose bolts or replace any damaged gaskets. Let the engine run for a few minutes to allow the exhaust system to heat up. This will help seat the gaskets and ensure a proper seal. After the engine has warmed up, inspect the exhaust system again for any leaks or issues.

Tips and Tricks for a Smooth Install

  • Soak Those Bolts: Seriously, don't underestimate the power of penetrating oil. Apply it liberally and let it soak for as long as possible.
  • Use the Right Tools: Using the wrong tools can strip bolts and make the job much harder. Invest in a good quality socket and wrench set.
  • Don't Force Anything: If something doesn't seem to fit, don't force it. Double-check the part number and make sure you have the correct exhaust system for your G37.
  • Get a Buddy: Having a friend help you can make the installation much easier, especially when removing and installing the exhaust system.
  • Take Your Time: Rushing the installation can lead to mistakes and potential damage. Take your time and do it right.

Common Issues and How to Solve Them

Even with careful planning, you might encounter some common issues during the installation. Here's how to troubleshoot them:

  • Stubborn Bolts: If you can't remove a bolt even after using penetrating oil, try heating it with a torch. Be careful not to damage any surrounding components.
  • Exhaust Leaks: Exhaust leaks can be caused by loose bolts, damaged gaskets, or improper alignment. Tighten all the bolts, replace the gaskets, and make sure the exhaust system is properly aligned.
  • Rattling: Rattling can be caused by the exhaust system hitting other components of the car. Adjust the hangers to provide more clearance.

Enjoy Your New Exhaust!

Congratulations, guys! You've successfully installed your new ISR single exit exhaust on your G37 sedan. Now, go out and enjoy the enhanced sound and performance of your ride. Remember to check the exhaust system periodically for any leaks or issues. With proper care, your new exhaust will provide years of enjoyment. Now, go turn some heads with that awesome sound!
