headers

I Daily Drove my nickle-plated TTIs for six years and had to repair the merges twice where the gravel and snow and salt collects. And they needed it again in the sixth or seventh year.
For me it was no big deal cuz I was swapping engine twice a year anyway. But if I hadnabin, that would have been exasperating ...... to say the least. For the price of the TTIs I couldda had almost 3, "off brand" header sets, and not had to do any repairs.
So IDK, IMO; Nickle-plated TTIs are not the bees-knees, for a DD.
