Except for the look. Headers on a street truck are not needed.Ever take a ftermarket amp out of a 2000's vehicle? Man way to much wire and splices everywhere! Need to get some more rachem splices, ran out used 30 or so yesterday and no where near done. Have to love the monster speaker wire going to the factory 18 gauge wire. Sure that helped. This guy liked gadgets. Low jack, signal amplifiers, filters, after market (jacobs) ignition. Just found out the person I bought it from has a set of NOS headers for it for $400. Wish I knew that before replacing the exhaust pipes and muffler.
