Hello, any recommendations out there on newer style coated or wrapped headers. My old headers finally gave out about a year after I wrapped them with the head shield wrap. It was expected - but you know... So now is the time to upgrade! Something that was more geared to low-end torque would be good but there may not be a lot of choices.
