What would installation of a muffler cost?

[TNurburgring]

I don't have the tools (and skills) to fit a muffler myself... Do you guys have an indication of what a muffler installation would cost?

No more than an hours labour I would think, maybe even 30 mins. Mine was done for £60

Took me about 20 minutes to change mine laying under the car on my driveway.
