Exhaust Installation - Fair Pricing ?

[PHOENIX]

Quick break down.
I purchased Edelbrock TES headers 6827 - driver side header wouldnt clear clutch linkage.
BTW I am selling these Edelbrock headers on the parts board: Click Here
I purchased Hedman Headers 69481 - driver side header wouldnt clear clutch linkage.
So I purchase Edelbrock headers 6527 - direct manifold replacement, use stock y-pipe.

My y-pipe is in good shape so I planned to use it, untill I get the headers and read the instructions. These are a direct replacement for the manifolds that sweep under the spark plugs (as used on 1980 and earlier). So this makes me unhappy. I go to a junk yard and pull a y-pipe off a 1980 Big10 that had these under sweep manifolds. On my way home I stopped a few places to find something to convert the stock y-pipe to 3" because thats what I am going to run. A local Meineke tells me they can custom build me a y-pipe for $60.00. Sounds like a fair price to me, so I decide to see how much they will install everything from the headers back.

I will supply the pipe, cat, flanges, muffler and gaskets for the flanges. They will need to bend pipes, weld were required and supply/install hangers. At max they may need to supply an additional few feet of 3" pipe to go over the rear axle.

They said they can build me the y-pipe and install everything for $100.00.
Price seems pretty fair to me. What do you guys think?
