I am thinking of either Vortex, HKS or RCM motorsport replacement for my P1
Would like thoughts on any of the above if you have any please

I have 3" RCM on my p1 plus their tubular headers - I had the noisy centre pipe and slash cut back box ( not Team ice), It was just too much on long motorway runs so i swapped the centre section for RCM's "quiet" centre section - stills sounds good, just took that edge off. Beautifully made of course.
