Agreed, it is a lot and a bit suspect. I've done the intake before so it seemed excessive and enough money to motivate me to get out there and DIY. Since I don't actually need to remove the intake I won't need to disconnect those wires in back it sounds like.That's a lot of money to remove the intake manifold. Comes off in less that 10 minutes.
But, the manifold can be lifted up at the front to access the Y pipe.
I got the revised quote and the grand total is huge but they are doing a lot of work and I'm hopeful they will do a good job. I'd like to get input on it though if anyone has any thoughts or sees anything else a bit suspect. I called the shop that did my a-arms for a 2nd quote on the trans filter and fluid and it was $100 more. The brake fluid flush seems high by $100, I think I paid $75 on my vettes but it isn't too high to where I want to buy a vacuum pump and DIY. I won't be changing it again probably for 100k miles.
