AR 2.5in mandrel bent exshaust system

[1972k5blazer]

Im gonna change to manifolds and re route exhaust system . I ve got a dyno max 2.5 in mandrel bent exhaust system ( looks aluminized) still on my 70 4x4 blazer has h pipe , thrush mufflers , and a set of coated headers . I wanna sell everything from the headers back (They sound good) . Was on blazer when i bought it i think everything is less than a year old everything still looks like brand new. Not sure what brand headers are they look like the coated headers in lmc that are $299.95 but not sure what brand. I would like to get $300 for all of it headers to the tail pipe . I will take pics and send if someone is interested. Thank you
