Default Question regarding exhaust setup with VF34 map

I am hoping someone from Cobb can chime in on this. I just did a VF34 upgrade to my 05 wagon with all the supporting mods, flashed to the Cobb OTS map. My question has to do with the exhaust. I am currently running a Cobb catted dp mated to a Prodrive axle back. The problem is that this setup is a bit too loud for me and I want something a bit quieter. I was wondering if it's possible to run the STI catback instead of the Prodrive. I am not sure how much quieter it will be. Although this exhaust sounds fantastic, it's a bit too much day to day. I know I would have to get a protune after but I am wondering if the STI catback would be acceptable with a VF34. I know I will also lose some power but reliability is what I am after at this point. I would be happy with 250 hp/tq.

That is perfectly fine - the only issue would be that you may be down on power, especially on the high end, relative to a full turbo-back aftermarket exhaust.
