When it comes to Toyota GR vehicles, there is no shortage of enthusiasts looking for ways to enhance their driving experience. And what better way to completely transform your daily driver *or track toy* than with a performance cat back exhaust? While our product suite has been on the market for a while now, we still get one question in particular on a regular basis:

Why did you go with 4 tips instead of the factory setup of 3?

Well, that one is kind of a two-part answer. First and foremost, we wanted to stay true to the OEM design of the vehicle. Gazoo Racing put center exit tips on the GR models and we were determined for our design to complement the vehicle rather than change its look. And as we went through the development process, we wanted to offer something that no one else on the market would have. By taking the factory center oval and enhancing it with dual GT-100 tips, we felt it gave the rear of the vehicle just enough of a visual enhancement to be unique without sacrificing the styling. There’s also the added benefit of being able to select different finishes for the inner tips compared to the outer tips, if you want to go that extra step in making your build unique.

And secondly, we wanted to pay homage to our British heritage and one of the most popular vehicles of the past few years - the GR Yaris. While the Yaris is not available in the US, it is the sibling to the GR Corolla and certainly one of our most popular customer vehicles of all time. Our GT Dual set up on the GR Yaris was so good looking, that we wanted to continue our GR path with all GT aesthetics on the Corolla. For us this meant getting rid of the oval tip in the middle and unifying the style with a Quad GT option.

Choosing Milltek’s Cat Back exhaust system for your GR Corolla is more than just a performance upgrade; it’s a celebration of automotive design and engineering excellence. By staying true to our successful GR Yaris design and integrating it into the GR Corolla, we’re offering a product that’s both functional and iconic. Available in both primary and secondary cat back, with resonated and non-resonated options for each, the GR Corolla Suite has something for everyone. 

For those who crave a distinctive exhaust note, improved performance, and an eye-catching aesthetic, the Milltek Cat Back system is a natural choice. Elevate your driving experience and make a statement with an exhaust system that honors our past while pushing the boundaries of performance and style.
