Header practicalities
I've been considering headers for my '85 GMC 2500 for a few years. One mechanic said they're a pain because they have to be removed for some routine maintenance. Also wondering how they might affect my emissions inspection here in AZ.
This is my everyday driver, putting on about 6000 miles a year since I retired. What realistic performance gains could I expect? There is no cat system on the truck. |
