Well..... thanks for the replys. enough said! I shall wait and while im waiting get an exhaust and do the lot all at once. invaluable advice, flash tune salesmen say "she'll be right mate, nearly as good as a custom one & very safe". Dont think the missus would like if I rock in the door going " I was racing this clubby n the phoon was going hard, then I heard this huge BANG...... etc" Has already cost me enough, dont need to keep spending unnescessary cash on it, that's for improvements, not replacements.
