Are those prices including a dyno tuning? If not, those estimates are very high, in my opinion. Even if it includes a tuning they are high! As you know, It is not that big of a job, they are charging you a steep Corvette Tax!. I hate that and highly recommend to keep searching for a better shop. I had LT headers and X pipes installed on my 2008 about a year ago. I have a garage but I rather pay someone that is competent as long as the price was reasonable. As you done it before, you know that It is not brain surgery or rocket science. In the Corvette it is easier than in most cars, definitely a lot easier than on a Camaro. I did some research and learned that it is a very easy job if you know what you are doing and specially if you can do it on a lift. I shop around and got similar estimates from local "Corvette" shops, I didn't like those prices so I kept looking, calling around and posted here asking for local shop recommendations. I ended up finding a small shop, but experienced Corvette guys, their quote was about a third everyone's else. If I remember correctly their quote was under $300 dollars and they told me it would take a couple of hours. I was a little hesitant at first cause all the other estimates were so much more but I decided to give this shop a chance. Made the appointment and took my car there. The shop was small but well equipped, clean and organized. It was a father and son shop, and they knew exactly what they were doing, They used a lift and power tools, I got to watch the whole swap, it took them one and a half hour from start to finish! Up and down the lift 3 or 4 times, done! These guys are really good and knew the job well. This job shouldn't take more than 3 to 4 hours to any professional shop. I saw it with my own eyes, 1 1/2 hours!
Can you rent a lift? I live in Miami and there are several "Garage Yourself" places that you can rent a lift by the hour. Very reasonable prices. If you research the job, organize all the tools and since you have some experience, you probably can do it in 4 to 6 hours on a lift. Or just keep searching for a local shop without the Corvette Tax. Call around some more, ask around or hopefully someone here might recommend a decent local shop. Good luck and let us know how it goes. Cheers!

 

those prices are WAY out of the park. I took my time doing mine and if I remember correctly it took a little over 3 hours.
