An axle-back exhaust system is an aftermarket component that replaces the section of the exhaust system that sits behind the rear axle of a vehicle. It includes the muffler, tailpipe, and any other associated components that connect to the exhaust system after the rear axle. Upgrading to an aftermarket axle-back exhaust can improve the sound and performance of a vehicle, but it typically does not significantly increase horsepower or torque. The primary benefits of an axle-back exhaust are improved sound quality, reduced weight, and a sportier appearance.
Fitment is verified against the manufacturer application data for this part.

The axleback exhaust for my 2015 Lexus is absolutely badass 🔥 it sounds great and it was easy to install, as all the proper bolts and hangers were included. My car finally sounds like a sports car!
Easy install, fitment was on point. Sound is much better at idle for sure, not crazy about the drone you hear at higher rpms but it was expected. Love the looks of them.
Really easy to install. The exhaust note is really nice in the high rpms. Pretty loud when climbing hills or accelerating through lower rpms. Cold start is way nicer.
Only took a week to get delivered and good response time when I contacted them for a question. The exhaust sounds really nice on my rc200t, the video doesn’t do it justice at all, sounds super nice especially when just driving slowly in ur neighborhood or a drive through because you can really hear the deep exhaust rumble. I’d recommend this to anyone who’s thinking of buying, especially for the price it has. Also very quick to install, i had a friend install it for me bc he knows more about that stuff and it took less than an hour.
Have a 2020 Lexus rc350 fsport AWD, just got the exhaust put on last night! It’s a very nice sound- very deep and sporty. While I am still trying to decide if it’s too loud for me or not, the install was very simple, it’s exactly as described online and with photos, as well as quick shipping! So 5 stars for that alone. Thank you guys!
I love this product, my dad had them on in an hour, super easy process and my once no noise car sounds way better now than it did before. Very worth my money. And the burnt tips are stunning 🙌
Very easy to install if you know basic vehicle knowledge. Came with everything needed for install and took me about 30 minutes to complete, it’s not loud but just the perfect sound for my 200t. I Definitely recommend this axle back to anyone interested.
Install was super easy! Took about half an hour including jacking up the vehicle. I suggest you have the exhaust hanger removal tool prior to installing! The burnt tips look great and the sound is amazing. No drone cruising on the highway, but great sound when getting on the gas. Would highly recommend to anyone thinking about modifying their exhaust on their RC350.
