OTL GRC Street Series Catback Exhaust System - 2023+ Toyota GR Corolla

Fitment is fairly decent but the valve controller box which was said to have come with 3m tape did not have any, and the oem valve makes a beeping noise whenever the car slows down.

This exhaust sounds amazing!.. Nice low tone, not raspy at all. With th valve open there is a bit of drone when you’re on it, but still sounds good for being essentially straight piped at that point. Valve closed sounds low and quiet with a bit more bass. Marginally louder than stock, especially when you get on the gas a bit but still very respectable. Really compliments the three cylinder's unique sound. Super easy install, don’t on my lunch braak. Very straight forward except I put the stock motor in the trunk as I live in a snowy region. Great guys to deal with,amazing customer service and support!

Great sound!!

Overall a easy install, adds a fantastic sound to the car.
