OEM exhaust valve bracket
In process of engineering our OTL 23+ GRC Catback we discovered removing the OEM valve eliminates the pesky CEL that comes up. Our in-house fabricators came up with a bracket that can protect the OEM valve while maintaining a clean aesthic. Made from corrosion resistant high-grade 304 stainless steel and paired with zinc plated hardware for protection from the elements.
Installing Bracket Correctly
Be sure to make sure bracket is installed correctly. Installing incorrectly can result in loose fitment or a rattling noise.

Customer Reviews
Absolutely great experience buying from OTL! This exhaust is loud when you want to be and quiet when you need to be!! They took their time with this exhaust!
I bought my 2024 GR circuit edition at the beginning on march, since I bought it I started looking for an exhaust system that wasn’t to expensive! I started looking around and ran into a video on the OTL exhaust! To tell you the true I felt in love with the design and how it looked! I liked the sound and you can tell from pics and video that it was good quality! That price also caught my eye and I decided that I was going to go with this kit.
When I went to the website it wasn’t even out on the market yet, lol I had to wait like two months before ordering from them! It was a long wait and finally the day came to order it. The first day it was available on the website I put in my order. I thought well let’s wait another 2 weeks or so for it to arrive, and I was wrong, I had it with in 3 to 4 days at my front door.
Finally I had my hands on an exhaust system, when I opened the box and saw the quality of it I was surprised of how good it looks. I went ahead and pulled up their installation video and started installing the exhaust on my car! An hour and 15 minutes later I was done with the installation, and when I turned on the car I couldn’t believe how amazing the sound is in person, and I felt in love with it all over again! Now I can’t wait to get my down pipe from OTL and match it with the catback system.
THE WAIT WAS WORTHY! If you are looking for a reasonable price, well made, great sound, easy install and B E A U T I F U L L exhaust system don’t even hesitate for a moment and buy this system, I know you will love it.
I almost forgot…. When I bought it I didn’t even realized it comes with a control that you can open and close the center valve, just imagine when I opened the box and find out lol….. I hope this review helps you make your final decision and pull the trigger on your next purchase!

Love the exhaust sounds amazing but the only concern I have is I cant get the center tip to fully tighten down and it slowly backs off and I have to readjust it
I love the way the exhaust sounds. Installation was a breeze. Didn’t take long at all to install. Very pleased with the burnt tips looks really good and clean.
off the line performance knocked it out of the park with their cat back exhaust I'm very pleased to say that the packaging and craftsmanship and most of all the sound is top-notch and definitely the most competitive price out there for exhaust systems for gr Corolla. It didn't take long to install and is very straightforward. The key fobs are great but I would like to see a OEM style button to put in car, would definitely add a OEM touch but that's something I can look into later on.
The only complaint I have is that the exhaust valve rattles if you decide to go halfway in between open and close. What I'm noticing that could be causing this issue is the OLT Cat-Back does not utilize exhaust springs to mount to the OEM mid pipe causing excess visible vibration through the exhaust possibly hence the reason for the rattle of the valve. But that's just my first diagnosis I will dive into a little bit further to see if there's anything I can do to reduce the vibration or figure out why the valve might have a little bit of play. But by no means that this means that the exhaust valve is crap. The valve works as it should and seals very nicely when shut.
