alright i was wondering how they run a single xhaust with headers, like just one exhaust but like 1 muffler with 2 outlets because i understand some of the concept but nit the rest? Like the y-pipew does it connect to the headers thne to the exhaust?

 

yeap, headers or stock exhaust manifolds bolt to the y-pipe, which has two pipes that merge into one pipe, roughly in the shape of a "y" or in the case of the stock "y-pipe" more of a "t"-shape. the single pipe coming from the y-pipe then attaches to the catalytic convertor. from there the catalytic convertor bolts to the intermediate pipe, which runs from the catalytic convertor, back the length of the car, over the axle and into the inlet of the muffler. the muffler is of a crossflow design and has 2 outlets where the tail pipes are attached.

here is a very crude diagram i made using my "fantastic" art skills

 

pretty drawing, You use photoshope to make it, looks like you spent our.

OR maybe a couple minutes in paint.
