As for Shooteer, the Librands 4 exit (as seen on my old S1) is my favourite - I prefer the sound to the sidepipes. This is an unconventional view - most prefer the sidepipes!
Carrying on a thread in the for sale section (where I want to sawp my sidepipes for a Librands or similar), does anyone know a reputable company in the south east who can do exhaust work? As suggested by you lot, getting an engineer to tune the sound to my preferences may be a better alternative than replacing...
Harry, Kin got his side pipes worked on and ended up with a much deeper more permanent 'woofle' and less of a bark. PM him for details?
