hey guys im in the market for a race header and i was curious if anyone has tried this obx race header. i know there are different versions but i dont see that listed here. i need to make sure it fits a k24a1 so if anyone has any ideas if it would or know of anyone running this on a k24 please chime in. also if this will not work what header will? i want to stay ep3 specific being as thats what my exhaust is and i dont want to mod it or buy another mid pipe. thanks

I have that exact one but the DC5-S spec, it cost me about $20 to get it modded to fit my exhaust greddy evo TT exhaust (ep3 specific), find that one and go with that cause you'll definitely see nice gains with that.

I bought the same one as Passenger. the DC5-s.
It fits well on my k24a1. but does come close to the stock front sway bar.(04) and my double x bar.

I'm running stiffer mounts so I only get a mini vibration at low idle or when really tromping on it.

The mods I did were bending the heat shield abit, discarded the cat and made a new mid pipe, I kept the stock muffler and resonator.

It sounds great, still factoryish quiet. the only droning i get is around 1700-2200RPM.

I've ran almost 20,000 kms and haven't had any problems yet.

best mod for the price. I think em2 front sway bar (that you can get from clubrsx or honda) clears it better. I have ESMM and get no vibrations, but thats with the k20a3 though.

Good question, I don't believe so though. From my understanding its just the civic ex/lx/dx from our year Si's, there shouldn't be any significant difference between years I don't imagine.

I know my mom's 05 EX sway is the 15.9 mm. I don't think DX models have a sway bar. But 05 is the for sure year.
