Re: Is this worth it?
Sounds a little high to me, unless they're Borla headers or something. A brand new Lock-right ought to set you back about $250...used ones $100-150. So are the headers/flowmasters worth $250? What brand headers? ceramic coated? stainless? How long has he had 'em? Plain jane painted headers for a v-8 run about $150 new. I dunno what straight six headers run, I'd think close to the same.
Find out a little more info on the headers and how long this stuff has been on his jeep.
