I paid a tech at work under the table, motors guide pays about 7 hours for the job, most shops depending on labor rate will be between 600-800 unless they do not know what they are getting into, I asked him today if he would be willing to do more sets for anyone local and he has no issue with it, he is a young guy with a mod addiction as well, but he is a honda guy
HOWEVER he has one of the cleanest and tasteful civics you will ever see...He is a training master tech in the honda PACT program, one of few young people that are not a total f5^k up these days...I applaud him for it, thus why I trusted him to do it. He did it for $250 bucks(he though 300 would have been fair, but I got the co worker discount), word of the wise, prepare for o2 sensors, the thread ripped right off them and there is only 20k on my car, ans he soaked them in blaster overnight and used some heat, no one in the shop was expecting that, myself included, we pull sensors out of high mileage honda exhausts all day long.
