Just had the new Ragazzon stainless exhaust fitted minus a centre box, it's not very loud at all just a nicer tone (thanks for the tip MT). On Saturday I also got round to fitting the 145 intake pipe to replace the masses of black plastic boxes on the 155. I already had a K & N panel filter fitted. Have only done a bout 15 miles and already it feels a lot more responsive in the mid range but I have'nt really revved it so no comment yet. I'm sure from others comments that things shoulod improve after a few more miules when the ecu learns its new settings or whatever. Even now though I am very happy with the set up.
It was once said that the meek shall inherit the Earth, I have since discovered that the meek don't want it.
