Hi, I'm looking at sorting the intake and exhaust on my 05 rxp. I know what pipe to use now for the rear exit (opas fitted) and was just going to fit the riva intake pipe and cone filter. Whilst looking tho I came across another bit of pipe, the riva freeflow pipe, is this for people not wanting to do a rear exit and use the OE exhaust hole?

any recommendations on other products? I'm not maybe as hardcore as sum, so will be leaving the original header. Just wanting the engine to breath well and a sound that will make others shudder when its revving!
