Sounds like you have a downpipe with separate parts for main and wastegate, twin dump I believe they are called. Should be ok as long as the divider does not foul the wastegate.

Different views from different people, it will be an issue if it fouls the wastegate when it opens

Hi there

You are probably have Divorced Downpipe,which looking like this



If you will have this,should be OK,but this will depends on the turbo what you are thinking to run,I've run only Bellmouth DP

Difference between the DP,Classic DP is longer and New age is shorter,but if you will be using full exhaust will fit without the problem

Hi there

Just upload the pics and I'm sure people will confirm will fit yours.There is no difference between the Impreza DP(although Twin scroll DP are different)

We are run classic exhaust on our wagon without the issue,classic exhaust will fit on any new age without the issue and will be safe
