Over $6000 to install TTI headers on 66 Barracuda

It's because of rip-off shops like this that I became a mechanic. When I was a kid I had a private garage replace a clutch. when I picked up the car the price had doubled, taken a week longer than estimated and stated no warentee because I was a kid and hot rodded the old clutch. When the new clutch went out 2 weeks later (never felt right from the beginning) he stated I must of been beating the sh*t out of it and no warrantee. That's when I learned to do it myself and it looked like he put in used parts But it started my career. But $6000 to put in a set of headers is ridiculous, he could of pulled the motor or the heads and put the headers in and re-installed the heads and it wouldn't cost that much.I hate people like that. He thinks his time is worth that much $$$ even tho he can't do the job. He wants you to pay for his education. Sorry , wish I was closer to help you out
