Product Details Technical Specs Installation Instructions

The MRT BRZ Sport Touring Axle Back Exhaust is how the BRZ should have sounded from the factory. This performance exhaust replaces the stock mufflers to give your BRZ a healthy note with a clean, smooth tone that is very sporty without being overwhelming. MRT team engineers also packaged the mufflers tight to the rear bumper, providing lots of clearance for when the road gets a bit rough.

If you want to hear a little bit more of the boxer engine at low revs, this MRT exhaust is the right system for you. Designed for the second-generation (ZD8) Subaru BRZ introduced for the 2022 model year, the MRT Sport Touring Axle Back provides an on-demand sound that is great for a daily driving setup. It shines at high RPMs but stays under control on city streets and in crowded neighborhoods. Since the Subaru BRZ is mechanically a twin to the Toyota 86, you can also use this system as a Toyota GR86 axle back exhaust.

Make Your Mark with an MRT Exhaust

MRT handcrafts this Subaru BRZ ZD8 Axle Back in corrosion-resistant T304 stainless steel for improved performance and durability. We use 2.5-inch mandrel-bent exhaust tubing that minimizes restrictions. The dual tip exhaust has standard polished stainless steel four-inch tips with an optional Black Ops black matte tip finish. This system is engineered for the best sound to match your BRZ and provides increased performance from the increased exhaust flow.

An axle back exhaust literally offers great bang for the buck and is easy to install. It takes only 60 minutes using a rachet/socket set and other common tools.

4 of 5 Sounds good but fitment isn't the best April 23, 2024
Reviewed by: Marq  
So the sound on this exhaust is amazing my only sad news about it is that the left muffler when attached to the rest doesn't have the nest fitment. I tighten the clamp that holds it so tight and yet it still has a leak.

Team MRT Comment:
Marq, thank you for your feedback.  Exhaust band clamps work nicely  on this application with proper installation.  Visit our YouTube channel to view a video on band clamp installation.

5 of 5 Exactly the OEM+ sound and look I was after March 15, 2024
Reviewed by: David from Berkeley, CA  
The MRT Sport Touring Axle Back was exactly the OEM+ exhaust I was looking for. The exhaust has a deep bass presence which adds to the BRZ driving experience without being obnoxious or too loud. Once the revs are up (I'd say over 3,500), I hear induction noise over the exhaust (I have fake engine noise off). This is exactly the balance I was looking for. Deep bass exhaust at low revs and actual induction noise at high revs/acceleration.

The tips are perfectly sized for the lower bumper openings and look good.

Installation was easy. I had a different experience from another reviewer. I used hand tools only, no problem. But I had ramps, so maybe I had a little more space to get better leverage.

Fast shipping.

Extremely satisfied at this price point and ease of installation (axle back). Thanks MRT!

5 of 5 Great sound and look. January 23, 2024
Reviewed by: Seth from Hillsboro, OR United States  
Nice improvement over stock, lighter ad distinctly better sound.

One quirk is due to the way the driver's side pipe attached, at idle there's a slight venturi effect, and most exhaust comes out the passenger side. Makes for a fun cloud generator in humid cold weather. However once the revs are up and you're driving, exhaust flows through both sides.

No noticeable drone, and a very pleasant tone over stock. Can't beat this option for any where near this price.

5 of 5 Excellent August 17, 2023

High quality product. Sounds great. This is the one you want if you're looking for OEM+ sound and not boy racer loud. Shout out to TheTopher for making a video of this. I wouldn't have known about it otherwise.

5 of 5 MRT Nailed it August 6, 2023
Reviewed by: Juan V from Philadelphia area  
Very happy with  the product and the result for my ‘22 MT. This exhaust adds a subtle authority to the sound of the BRZ (which was needed, in my opinion.)  Fitment is solid and appearance is nicely understated. That said, the best thing for me is how this setup totally elevates the driving experience.
