Hey Guy

Can I get some advice on two things

1st: When adding the new muffler should I add larger exhaust pipe from the Cat to the muffler. Someone told me this would help with exhaust flow,but I don't see how. I could understand if it was from the headers. I don't know you guys tell me.

2nd: Which one of these you think would look and work best (I think #UN7831)
