Hey peeps, looking for OEM exhaust from Civic Si's or S2k...

The point is that i'm trying to stay stock while still letting the engine breathe better than my stock Dx exhaust! it's a puny little diameter! especially since I have the basic bolts (I/H).

If you think you have an exhaust that would be quiet, non-OEM, let me know, i'm open to options...

NO Fart Can's or ricer stuff please!

thanks
