Cat Back Exhaust Systems

Hi, wanting to look into what companies made off the shelf exhausts for n15? (Specifically in this car 2dr vzr)

I currently have a 5zigen cat back however heard its somewhat restrictive to meet JASMA certification.

Ive tried looking on nengun but couldnt quite find a way to sort by car, so it meant opening brand catagories then searching, which really didnt go well.

I do have a custom 2.5 inch system built for sss, its pretty good but im feeling that jdm tyte bug. Gotta have more jdm. U kno mang???
