Thruxton Arrow Exhaust

i have a 2015 thruxton 900,i had TOR'S fitted from new,i've noticed recently there are a few blemishes on the chrome (which i thought were due to stone's hitting the silencers),it appears not to be the case,i took it to my local triumph dealers today to ask there opinion & the cause appears to be rust under the chrome,it's causing the chrome to bubble in several places on both silencer's.prior to buying the bike i saw one with the stainless steel ARROW'S fitted which looked nice, they were £995 plus fitting at the time i asked how much are they now, he said £995 plus fitting, he then looked on the system to discover they are now £507 plus fitting,i couldn't get my card out quick enough,that's nearly half the original price, booked it in for the 16th of september to have the arrow's fitted

 

i hope they sound as good as, if not better than the TOR'S.i missed out on making a warranty claim on the tor's by a few month's, that's if they were covered for 2 year's as the bike was.
