Parts & Accessories Spare parts Full cat back with 3-inch exhaust pipes. The cat is custom-made by one of the best shops. It's similar to Corsa, and the cat is old and discontinued. Its sound is very musical. It's clean and guaranteed against leaks and welding. I used it for approximately 5 months, and most of the time the car was parked. I'm not someone who floors it or drives it hard. Very clean usage.
