Deleting the secondaries requires cutting the exhaust. Aftermarket mufflers that work with NPP start at $1200 and also require cutting. Primary cat delete pipes are about $400 and a tune is $500, so you're all in for about $900. It's also completely reversible and I can sell the pipes when I'm done with the car. All of this makes it a much more attractive option, IMO.
