Best Catback Exhaust EVER?! Installing OTL GRC Street Series Valved Catback

Transform Your GR Corolla's Exhaust with the OTL Street Series Valved Cat-Back System

If you own a GR Corolla and have been dreaming of transforming your exhaust from a tame factory sound to something truly aggressive and commanding, then you're in for a treat. Imagine your exhaust going from stock to something that turns heads at every corner. Whether you're cruising with friends or tearing it up at the track, you want an exhaust that delivers both performance and sound. That's where the new OTL Street Series Valved Cat-Back System comes in.

Introducing the OTL Street Series for the 2023+ GR Corolla At Off the Line Performance, we’re excited to introduce our latest innovation: the OTL Street Series Valved Cat-Back System, specifically designed for the 2023+ GR Corolla. This system is engineered to enhance your car's sound, performance, and style, all while being easy on your wallet.

Key Features of the OTL Street Series

1. High-Quality Craftsmanship

Every OTL Street Series exhaust is crafted with meticulous attention to detail. Our mufflers come with the OTL stamping, a mark of quality that speaks volumes. You also have the option to choose from various tip finishes, including burnt, polished, and soon-to-be-released black chrome. Each tip option allows you to personalize the look of your exhaust to match your style.

2. Valve-Controlled Exhaust System

One of the standout features of our cat-back system is the valve-controlled exhaust. Operated via a key-fob, this system allows you to switch between a straight-pipe sound for an aggressive note during spirited drives or track days, and a quieter, muffled tone for everyday driving or early morning starts. This flexibility means you can enjoy the best of both worlds without compromising on sound quality.

3. Affordable Performance

We believe that upgrading your exhaust shouldn’t break the bank. Priced at just under $1,600, the OTL Street Series Cat-Back offers exceptional value, especially when compared to other options on the market that often exceed $2,000. This makes it a perfect choice for those just starting their car modification journey.

Retaining OEM Features with Added Benefits

Concerned about losing the functionality of your OEM valve system? Don’t be. Our system includes a bracket that allows you to retain the OEM valve controller. This integration ensures that you get all the benefits of our high-performance exhaust while maintaining the features you love from the factory setup.


Installation and Sound Comparison

When installing the OTL Street Series cat-back system, you’ll notice that it's designed for an effortless fit. The exhaust comes in pieces, making it easy to install directly onto your car. Even though we recommend having a friend assist you during installation, it’s something you can accomplish on your own with a bit of patience.

Before you start, make sure to unplug the factory valve controller to prevent any accidental damage during installation. Once everything is in place, you’ll need to realign the exhaust system to ensure a perfect fit. The final step involves hooking up the valve controller box, which is a straightforward process.

Finishing Touches: Choosing the Right Exhaust Tip

The last step in the installation is choosing and fitting the exhaust tips. Whether you opt for the burnt titanium, polished, or the soon-to-be-released black chrome finish, these tips are designed to perfectly complement your GR Corolla’s aesthetics. The tips are slightly angled to follow the bumper line, adding a refined touch to your car's rear profile.

Ready to Make Some Noise?

Once your OTL Street Series cat-back system is installed, it’s time to hear the difference. We’ve equipped our demo GR Corolla with the OTL Downpipe, so you’ll notice a slightly different tone compared to a stock downpipe, but the comparison will give you a great sense of the enhanced sound profile.

With the valve closed, you get a deep, refined tone; with it open, the sound transforms into an exhilarating roar. For those who like to measure their mods, we’ve even tested the system with a decibel reader to show you the difference in sound levels before and after installation (shown on YouTube)

Conclusion

Upgrading your GR Corolla’s exhaust with the OTL Street Series Valved Cat-Back System is not just about sound; it’s about enhancing your driving experience. With its high-quality construction, valve-controlled flexibility, and affordability, it’s the perfect addition for any enthusiast looking to make their Corolla stand out. So, are you ready to unleash the full potential of your GR Corolla?
