We are looking to move into an MPLS which uses a proxy to gain access to the internet.
I've read stories that it will slow performance?

I read other stories it will increase the traffic/data both WAN and LAN? if so, how?
Does it add and remove things from the header? Does this depend on the product i.e. Trend, Symantec, SonicWall.

My first thought was it adds another single point of failure but the MPLS with be part of a high availability setup with SLA's, so not too worried about that.

Any other considerations why not to use a proxy? 9 out 10 stories are reporting there is no benefit and it creates more work both implementing and support.

Sorry if it's a bit vague, if you need more info please let me know.

Is the Proxy inside the MPLS? Hosted by your MPLS Provider?  

It all depends on how your current sites accessed the internet before. In essence all your internet traffic has leave your org and end up on the internet one way or another.  Obviously if it is a hosted Proxy, and I am guessing that this is what you mean as it is the norm, then all traffic from all sites will use that single gateway/proxy to to get out.

It does not "Increase" traffic, just change where it is routed.

Yes there will be a dedicated circuit to the MPLS. So they will remove our FW.

Excellent thanks you've cleared it up for me in my head. I understood the routing changed but could not work out how the traffic would increase.
