Yes, it's stock. Did someone advise you to have 3" pipes?

No I did a lot of motor work to mine I'm close to 1000 hp so I needed the bigger pipe .you could go to 2.5 and be fine

I went with 2 3/4 inch aluminized pipe with Flowmaster super 40 mufflers. Nice sound thats not to overly aggressive. Total cost with mufflers was about $450. Stock pipe I believe was 2 1/2
