I currently have a pos OBX exhaust on my car because the shop I bought it from told me they were almost the same thing, just way cheaper than the 5zigen (this was before I knew a whole lot about tuning and stuff). I'm really tired of the look and sound of the exhaust but I don't wanna spend a fortune to change it. I was wondering if a 5zigen fireball or HKS Hi-power rear section would fit on the OBX midpipe since the 2 good exhausts come out at an angle (which I love). BTW, my car is a 92 civic sedan.
