Hey guys! New member here. Not the most well-informed person on modifications but I'm learning. Anyways, I have a 2011 G37xS. I bought the Motordyne catback and had it welded on (Due to transfer case as I'm sure you guys know). Anyways, sounded great but I wanted to add a HFC (Setup used OEM headers). Being that it's AWD, I can't direct bolt-on ART pipes so that's why I went with a HFC. The hardest decision was if I wanted to go with a resonated HFC or not.

With that being said, I went with Berks HFC for a few reasons. 1. I figured I could get a resonator welded on if I didn't like it. If I bought the resonated HFC and didn't like it, I couldn't just remove the resonator, right? 2. I would have to wait 6 weeks for the FI resonated HFC compared to 2 days for Berks. 3. Cheaper.

HOWEVER, I am a bit dissatisfied with my current setup just simply because of drone and it's a tad too loud. I don't mind loud, but between the interior shakes and anyone hearing me within a 5 mile radius at 6k RPMs, it's a bit too much.

Now I already knew that drone noise and whatnot may of been an issue, but I wasn't sure. So where it stands, I'd like to add a resonator and would like some suggestions or help.

Does someone have a direct link for a resonator that'll work for my setup, or is it more complicated than that? All in all, I just want to eliminate drone as much as possible. Hopefully with making the exhaust a little bit toned down but not too much. If I can get that done, I'll be completely satisfied.

Sorry if this post is stupid but I don't want to have to make an appointment a few weeks from now just to figure out the sizing for the resonator if someone here would know what I need. Plus, the quicker I can get the resonator added, the less likely I'll get pulled over by the police lol.

Welcome to the forum.
Cutting into your Berk HFCs for a resonator install leaves little room for error (straight cuts, increasing overall HFC length, exhaust flange re-mating to the mid-pipe, etc).
IMO, maybe working in a high quality resonantor on the y-pipe would be a better option. I have Berk HFCs and have been looking at this product:

There's a comparison video from 2013 listed in the review section that makes me in favor of this idea vice cutting the Berks which made need to be sold at a later date. Good luck.

First off, let me just say thanks for such a detailed response! That seems like a solid resonator as well! Pretty sure I saw someone on YouTube use the same one. Now, adding this.. Will it make a dramatic difference in sound or just a small amount? I don't want my expensive exhaust setup to be quiet lol.

Try the link and watch the video. He shows three setups: stock, with HFC/cat exhaust, then all that with the resonator. Your first say a little too loud. Youll have to be the judge.

For me the exhaust upgrade was performanced based not wake up the kids based.

Maybe the Motordyne XYZ Resonated pipe would be an easy bolt on option for you?

I'm kinda in the same boat. I have resonated test pipes but am getting HFC's welded in place. I'll let ya know how it goes in like 2 weeks when I get it all put together whether its a good idea or not lol
