oky, I got rsx-s axleback muffler, now I'm thinkg upgrade the rsx-s axleback pipe to 2.25 or 2.5" give more air flow, louder i think. so i know that rsx-s flange is bigger than 2dr civic LX flange, is that still possible to make it to fit on stock civic flanges. Anyone know what's pipe size on HKS axleback for those you have on your car?

anyone know where i can get quote for 2.25" or 2.5" mandrel pipe at S. Cali. 909 area?

thanks,
