Yup ZZP Catback is freaking loud and drones like crazy. Plus it's not necessary to upgrade exhaust until it becomes restrictive around 300-350hp which you'll probably never reach unless you really dig in. Go the the JY find a stock Wbody exhaust with dual outlets. Replace yours with the JY unit then if you still want a different tone cut off and weld on new mufflers. With the difference you'll save going this route instead of ZZP you can buy a set of headers or downpipe/Plog and you'll notice way more of a gain.
