Yes, you can just delete it. Make sure to use a mandrel oval pipe and then oval to round pipe as pictured. If you just use a cheap bent pipe you will restrict the exhaust airflow.
I noticed a significant difference deleting the secondary cat on my N26 with original muffler versus changing the downpipe from stock to ER catted 200 cell downpipe.
