it's called a down pipe, and stock it's 2 1/4". aside from where it looks like it's smashed toward the header.

Believe the down pipe is 2 1/2", the system turns into 2 1/4" after the cat.

when i did my exhaust i also did a new downpipe. if you can try to keep your STOCK downpipe do so, i hacked mine all apart thinking i'd just get a new better one and i could only find ones like in that amazon ad that aren't mandrel bent. the stock ones look like they would flow alot better

Take your stock one to almost any exhaust shop. They have a nifty little machine that will widen it
