If you're asking about whether you can do it. Like install the downpipe, midpipe, and secondary cat delete Yes. But I think only if you buy them separately. If you buy the turboback the first three pipes will connect with flanges, but the third pipe (secondary cat delete) will connect to the catback with clamps. The stock system uses flanges throughout up to the point where it's one pipe all the way to the back. So if you only want the first three pipes you can do it.
I also found this on the forum:
"Well, the install is complete. ZZP racing down pipe to custom straight pipe to factory muffler/tip. I thought this would be something of a sleeper system but the factory muffler can barely handle the straight pipe system; it's fairly loud. Little to no drone at highway speeds which is nice, and the turbo is definitely audible. I'm smelling some light fumes when I'm idling so I'm hoping it's just pipe coating burning off." From this thread:

I don't have the downpipe installed, but I have the rest of the turbo back installed and I can say it's loud but I haven't been pulled over and I rev it quite a bit. I also live literally down the street from the sheriff's department. Also there's an easy solution for the police if the car is too loud. Clutch in! Though I think if you look on YouTube you could find a video of what you're looking for. I think I saw one once but don't remember how I got there :/
Anyway, good luck!
