Message	but good luck finding one for the 2+2. That's what I run on my Z and it has very little drone. 72 decibel at 70mph. I tried a HKS and even with full cats it was unbearable so be careful with that thinking. Stay away from anything with straight through mufflers (MagnaFlow) or smallish looking mufflers. BillyBoat has a 2+2 catback with helmholtz resonators built into the muffler to eliminate drone but I don't have experience with those. Try looking up YT exhaust sound videos for comparison. Good luck!
