Exhaust mod

[mosti]

Booked in for wednesday but Might be canceling after calling up today.
This is what I was originally quoted last week.

2.5" highflow metallic catback $350
2.5" high flow metallic cat converter $350
install extractors $160

Total $860

How's that price look?

After visiting today to book it in he asked me what price he quoted me last time. I said around the $800 mark ( I clearly remembered the price of $860 but i wasn't going to give him exact).
So he grabbed his calculator out and said $100 for extractors to be installed....then he stopped talking and keyed in a couple of other things and finished up with "yeah, $800".

I booked it in for this wednesday and before leaving I asked him to make sure that it was a full system. He replied with "From the cat converter to your tip".

Now it didn't really click to me until I got home but he's charging me $700 for a metallic catback? Anyways, he must have made a mistake cause last week im quite sure he also mentioned high flow metallic cat. So I will call up tomorrow and let him know $800 for
high flow metallic cat
cat back
install headers

$800 seem fair? I'm using mt pre existing tip and collector pipe etc.
