Mines custom. I see your from Plymouth. I got mine done in longlife. Full system was £550 fitted.
Most members on here heard it at the rolling road, what were peoples views?
Personally I thought it sounded nice, not too loud but a little bit deeper tone to the milltek's.
Performance wise, I got good results which were similar to a similar setup with milltek (keiths) so don't think there's much in it other than price.
