Step 1 How to Remove the OEM Undertrays on a Subaru BRZ Initially, before starting on any project on the front of the car, you would want to get it in the air. Supported by Jack stands. There are various bolts on the back under tray that need to be taken off with a 10mm socket There are 11 Bolts that have to be taken off to remove the black under tray. Step 2 After getting the rear under tray off, its time to move on to the front under tray. Theres 7 black clips that require a flat head to pop out. Be careful not to break the head on these. Once they pop out, just pull them out of the hole. After the Clips are out, go ahead and use the 10mm socket to get the bolts out. There should be (8) 10 mm head bolts holding up the under tray. Once those bolts are taken out, the under tray will drop. Be careful not to damage the tray as it is a key item in the undercarriage of the vehicle. 2019 www.moddit.com/ Page 3 of 11
Step 3 How To Remove The Factory Exhaust on a 2013 Subaru BRZ To begin the removal of the Subaru BRZ Factory Exhaust you either need to get it off the ground on a lift or use jack stands to secure it above ground. In the images we raised the car on a lift but one can easily secure the car on jack stands as well. Step 4 Start by removing the central OEM hardware first, shown here. Our first step was to remove two bolts at the center of the center-most section (aka the Mid-Pipe) using one 14 mm wrench and one 12mm wrench. The 14 mm was used toward the rear on the spring side of the nut while the 12 mm was poised towards the front of the car. 2019 www.moddit.com/ Page 4 of 11
Step 5 Go to the rear of the car behind the rear wheel to remove the bolts connecting the two sections of the exhaust (The Center/Mid-Pipe & Muffler Portion). You will need to use one 14mm wrench and one 14mm rachet to remove the hardware from the center pipe to the muffler to disconnect it. In some cases you will not need to reuse the rear hardware or exhaust gaskets, if your aftermarket exhaust does or does not come with one. 2019 www.moddit.com/ Page 5 of 11
Step 6 White supporting the front, remove the exhaust center pipe from the exhaust bushings. Having an extra hand here would make it a lot easier here. It should be relatively easy to pull the support out of the exhaust bushing here. Step 7 Remove the two exhaust bushings closest to the rear of the car first so that the exhaust tips do not swing up and hit your rear bumper. Be sure to put some cardboard on the ground below your exhaust so you don't scratch the bottom of the exhaust muffler when it swings down. Lubricant spray will assist in separating the bushing from the support. 2019 www.moddit.com/ Page 6 of 11
Step 8 Have a another person support the exhaust and proceed to remove the other 2 exhaust bushings. Step 9 Before installation of your new exhaust, check the front exhaust pipe sealant bushings for damages as you will be reusing it. At this point your exhaust should be fully removed and you should be ready to install either a replacement or aftermarket exhaust. The stock Subaru BRZ exhaust comes weighing in at a total combined weight of 38.30 pounds. This includes both the mid-pipe and the muffler portion of the exhaust. 2019 www.moddit.com/ Page 7 of 11
Step 10 Unboxing Unbox your Tanabe Exhaust. It should come with all new gaskets and hardware to install onto the BRZ/FR-S The Tanabe Medallion is nearly 18 lbs. lighter than the stock exahust! 2019 www.moddit.com/ Page 8 of 11
Step 11 Install Mid Pipe Position the mid-pipe in the stock location Retain all your stock exhaust hanger bushings. You will have to reuse them when installing this exhaust. Near the rear of the car insert the hanger busing and insert the exhaust hanger. This positions acts as a pivot point to help position the exhaust and alleviate the weight Retain your stock exhaust spring nuts and bolts as they are also reused on the mid-pipe. Note: Pictured is an after market front pipe but it there should be no variation on installation on this particular exhaust Check the stock exhaust gasket donut, if there is not marring or deformation go ahead and reuse and reinsert Insert stock exhaust spring bolts and nuts. Hand tight for now; it aid in adjusting the exhaust positio 2019 www.moddit.com/ Page 9 of 11
Step 12 Install Axle Back Mount the axle back portion of the exhaust Again reuse the stock exhaust hanger bushings and hang the muffler. Since this a single exit exhaust only the driver side hangers will be used. Again this will act as pivot point for positioning Step 13 Insert Gaskets and Tighten Bolts Since the full exhaust loosely mounted go ahead and slip in the provided exhaust gasket.at the same time insert the provided bolts to keep everything together At this time it is a good idea to use loctite or any comparable thread locker the nuts for the exhaust Tighten up the bolts 2019 www.moddit.com/ Page 10 of 11
Step 14 Check Fitment Its almost done! At this point the exhaust system is on. Sometimes the muffler looks a little skewed or not centered. If left the bolts loose on the mid-pipe and axle back, go ahead and position the exhaust in the desired orientation While putting pressure on certain points, and if the exhaust is in the desired position, tighten the bolts while holding the exhaust in place. These steps is not often required, you can tighten everything up and fit perfect. The preceding steps will work for most exhaust installs This document was last generated on 2019-01-09 02:32:47 PM. 2019 www.moddit.com/ Page 11 of 11
