Hello John,You mention headers here. I have to replace my leaky manifolds and have considered the headers, but have been told it will be louder and hotter in the cab? What are the pros of the headers?Thanks,Eric

Look as these 2 pictures;

Pay attention to the torque values. Do it in stages and they should NEVER
over torqued!! Always use new bolts and use the small hex headed bolts for
the headers and standard grade 5 (FIVE) for the manifolds. I would suggest
a high temp antiseize for the for all the threads.

The copper could be used also.
