it's a company made Cat back, he sells mufflers and also bends pipe and makes catbacks with the mufflers he sells. I was going to buy from him but just got the mufflers off him for 53 bucks a pop and getting them welded in.

 

Here is a clip of my MAC catback. It is a few years old, I dunno if the coating has worn off or if it never came with coating on it since it was a few years ago. I bought it like this though. My dad was revving it kinda weak, but you can get the idea. I like the sound. Its actually pretty loud when you get on it.
