Is it just me or does the page don't have an option to either choose to configure the pipe with either the 4" Muffler or 5" Muffler? Does the standard--let's say I just hit add to cart and what not--come with a 4" Muffler or a 5" Muffler? I'm really set on buying this but definitely want the 5" Muffler for my neighbors' peace of minds.
