I bought a set of mint condition shiney Arrow headers of a guy on this forum,i have fitted them and they are now discolouring fast,on the first bend when they leave the head they are starting to go blue and the rest of the downpipes are turning a gold straw colour,is this normal? The bike has an ecunleashed map and an Akra can,it also suffers with surging around 2k rpm.it did this before but it's worse with the Arrows on,is it too lean?(hence the blueing),will this cause damage to the engine?
