HI, i sold for a friend , an Arrow SBK system with springs and db killer, mint condition like new. Full titanium , headers and pipe. 800£.
can't use them on track though, only on days where theres no noise testing, as without baffle 109 and with bewteen 105-106, depending on day….. I had one on my 2008 blade with BMC airfilter, PC5 and made 175 BHP on rear wheel….. but bloody loud though nice piece of kit there mate
as above,i had 1 on my blade,nice system but a real pain to get under 102db even after a repack+baffle. sold it on a and bought an akky
