For what you'll pay for the 10hp and 15trq from the exhaust and tune you would be better off going with ZZP's cat back and a Trifecta tune and go for the 30hp/35trq gain. I know you're probably worried about your factory warranty though.
I'm looking at these choices also and it's not about warranty. It's about the sound for me. Really want ZZP's turbo back system but concerned about how loud or might be.

Do you have a sound clip of this?If warranty is not a concern then go with the full turbo back with muffler. If it's still too loud (doubt it) add a resonator. I have the Anaconda + ZZP RS cat back without muffler and it is certainly way too freaking loud.
