New Downpipes

I recently bought and installed a new downpipe on my Honda CBR125R (2004 model) as my last one was blowing and rusted badly. I was hoping this would increase the performance, but my bike has now got no torque, is overheating, and has a top speed of 55mph (was previously 75mph). The only difference I can see with the new one is that this one has a baffle, could this be what's causing the trouble? My old one had the baffle removed but this one has an absolutely huge one 

Can anyone help me on this one?

Welcome Ryan,you know the answer Ryan you have added another baffle which is restricting the flow.

What end can has it ? Is it the Honda original? What can goes with the downpipe you bought?

Thanks jaffa, really appreciate it! Yeah I've got a scorpion can that was already with the bike when I bought it, but I've got the stock downpipe for a CBR125. I think the previous one was a modded stock pipe as it looks like someone had taken a drill to the baffle
