LS Auto/Chris Forsberg Racing got sent our Injen Exhaust recently and we just had to get it installed tonight. We have a full engine and cooling system ready for installation but we came by late night after hours to get our exhaust on and finally get some installations off our lap. We ripped open the box and found a great looking stainless steel exhaust.

Here are the first pieces that connect to your current car setup. The piece is polished and is a vast improvement from the factory option.

Here is the huge factory muffler in the back of the 350z factory. Injen converts this piece into a split two can piece that sounds much better and looks is leaps and bounds better ascetically. Not to mention the factory piece weighs much more than our aftermarket piece from Inejn.

The first step to installing an exhaust is to rip out the old one. This is something you can easily do with a basic socket set and some determination. Removing the large back piece is a two person job. This way you can remove the last bracket holding it up and not have it fall to the ground. Have the second person hold it and bring it safely to the ground as someone else removes that last bracket holding it up.

This is the factory rear section of the stock exhaust housing once it has been removed. If your looking for some great weight savings you can remove the heat shield trey you see above. We opted to keep it in place to protect our trunk cargo from receiving too much heat and the weight savings is not the biggest focus of the project.

Here is the front section of the Injen exhaust now installed on the car. Make sure you spend some time and tighten all the bolts.

Here is a close up of the exhaust tip and the perfect fitment on the factory bumper of the Nissan 350z.

Now that the exhaust is in place and securely on the OEM hangers make sure you re check your bolts on the exhaust so that they are tight. We even noted that we had a pretty loose one that our last second check which could of avoided us some headache on our road test later that night.

Here is what the car looks like after a simple 30 minute installation of the exhaust.

Here is a close up of the passenger side exhaust tip after we finished installation.

This is an under body shot of the Injen piece completely installed. You can see all the empty new space compared to the OEM install. This exhaust only uses the factory mounts so you have no problems with that for the install. This aftermarket piece looks so much better than that giant OEM piece. I was really shocked at the aggressive stance it gave the rear end of the car.

Here is a close up shot of the full exhaust we installed from underneath the car. Once we take the car off the lift you won’t see any of the exhaust again from the rear suspension forward.

Once we got home I snapped a quick shot from our parking spot of the 350z. Clearly I don’t have a knack for parking tonight which is okay since spot 122 is ours as well. The car sounds great on the inside and looks even better from the rear now. Big thanks to the guys at LS Auto for staying up extra late to help us get our installation done. Stay tuned to the 350z blog since we will be posting some videos of the exhaust at idle, at speed, and how it sounds from the inside of the car to truly give you readers a feel of the product.
