Cheers Muggz, will probably only need the tip
Genome's are actually quite restrictive as the inside of the piping
is actually alot smaller than the outside.
Found a few STi cannon mufflers on the net but dont really want
to sell a kidney for them, if it becomes a major hassle for the sound
(missus) then a Butler/Genome will prob be the go.
Pretty sure she will get used to it though.
