Answer
Hi David , I have never installed a header on a Nissan truck. I have a 94 myself. You may want to look through your Local Nissan dealers NISMO catalog. It is full of high performance parts for Nissans. If all else fails maybe the manual header can be modified  if interference problems exist.I will do some more checking for you on this. Mike
