Alright im just wondering if theres any OEM stock exhausts with a larger diameter that would fit on my EJ coupe, i got a d16z6 with a DC 4-1 header

 

Can you edit that so it makes more sense? The run-on sentences are kinda hard to read (especially at 2AM), and i'm not really exactly sure what you are asking.

okay cool.

hmm, OEM exhausts...

If there's a bigger one, the only one it is is the 99-00 Si exhaust. However, the so-called "size difference" I have heard that the Si has may only be a rumor.

If the 99-00 Si isn't bigger (since i'm not sure), then nope, there's nothing OEM that is bigger than what you have (that will fit).



EDIT: nope, Si is the same size. So no, there aren't any direct-swap OEM exhausts that will fit that are bigger than what you have.

 

damn that sucks, well i just need a whole new stock exhaust set up because having a gutted cat with no turbo/nitrous sucks. I need some back pressure with NA thanks though

 

If your looking for more back pressure then you dont want an exhaust with a bigger diameter.
