Going from Catless to Catted Downpipe Will I need a tune?

AA Catless Downpipes to CPE Catted Downpipe.

Currently running an AA tune, will be getting Pro-Tuned later in the week.
Is it safe to drive with the Catted Downpipe for a few days?

Thanks.

If your AA tune is for catless DPs, try to stay out of heavy boosting so you don't over stress the turbos from backpressure.

Not sure why you would do that but in any case you probably have to change maps since you will be over stressing your turbos if you are trying to make the same power compared to catless.
