Got these back in 2022. Ride so far and has become almost a slick! It took approximately 45,000 km to wear out with very aggressive operation. They stood on an all-wheel drive car with a power of more than 300 hp. As for the noise, I won’t say - it’s a hellish exhaust. They keep the road so that you can forget about everything in the world. Do not pass on the track. It's time to look for a new kit and the question "what to take?" - almost not worth it. Of course T1-R!
