Besides swapping to a drone free catback like Corsa or Solo performance you have a few options.
You can try a resonated mid-muffler to replace your X-pipe on the ARH. They come with an internal X style cross over. The results on this vary, generally you'll reduce a good deal of drone but you'll lose some volume with it.
Some people will dyno-mat their trunk and undercarriage. This cuts volume out of the interior real well and even though you'll still hear some drone it'll be a lot quieter.
Look into ordering a set of J-pipes. It's what Solo Performance uses on their catbacks to stay drone free. They would weld onto your existing system and should eliminate all drone while not interfering with the flow.

Had the same issue. Do a search, there was something about a J pipe. I turned AFM with a new tune.

I run the ARH 2" LTs, 3.5" Collectors, ARH Axle back.. No drone

heres what i found online:
Exhaust drone is primarily the result of sound waves traveling through the air and vibration that is transferred through a vehicle's frame, body

and components. Exhaust drone vibration may also be a result of sound frequency alignment between the engine and exhaust. When the frequencies are aligned, the result is a pressure wave between the engine and exhaust. Sound waves, transferred sound and sound frequency must be controlled to quiet the exhaust. Exhaust system modifications and the application of sound control material will reduce exhaust drone in your vehicle

put in 4.11 gears...that will raise up your rpms by 200-300, which should keep you over 1800 rpms most of the time...and the car will be faster too.

J pipes

Dynamat didn't do crap for me. I ended up removing it, which was a real pita... I ended up going with the ZL1 Corsa system.. No drone. I can finally use my phone while driving. Even the onstar lady sounds better. Lol

I'm no scientist but the j pipes worked great when I had stock pipes with a resi delete and pype bombs but when I put them on my JBA 3" they didn't help at all. I don't know if pipe diameter changes things. I'm sure Solo can chime in if I'm way off in left field.

VR Baron · 12-18-2012, 06:46 PM

I did insulation, helped a wee bit around town, not at speed.Did resonated x pipe, didnt help much either. J pipes only thing that worked with outlaw axelback and I dont have headers!
