They appear to be priced cheap. I seem to remember someone posting ages ago that they'll modify 'noisiness' to order. I've got an Afterburner decat (non-resonator) centre pipe and a Ninja and it's a bit antisocial. I've had a few comments and a headache after long distances, so I'm after something quieter without breaking the bank.
Considering Janspeed or H&S, but has anyone tried Piper?

I'm running a piper centre de-cat and back box on my my98 wagon with a nice four inch slash cut tailpipe. I think it has a nice sound, not too loud and quite a nice deep burble. Nice for pops and bangs too. Quality is good and had no probs fitting.
