Adding resonators

I have the aFe Mach Force cat back exhaust. I do like the sound but I want to lower the drone just a tad and I am thinking I need to add some high flow resonators right after the cats.

Anyone have recommendations on what resonators I should add? Vibrant? Solo? Others? Length?

I seen someone install the Borla S mufflers right after the cats on a custom setup several years back. I also seen pics of the Corsa that appears to leverage some good sized resonators right after the cats.

Re: Adding resonators

The length of resonator you want kind of depends on where the drone is. This is a really great post that explains proper tuning of a resonator.

Re: Adding resonators

I read some about j-pipes but I think I want to go the simpler route of just adding some resonators or even additional mufflers.

Anyone know what size resonator or mufflers I should get to install right after the cats where the cat-back bolts up to the headers?

Re: Adding resonators

Why not cut the valves off the stock exhaust and marry them into the piping? I wired mine open when I was running stock and I noticed drone afterwards. So they do help manage drone a little. Would be an inexpensive experiment option.

Re: Adding resonators

Interesting idea but I don't think the OEM exhaust on my 2016 had the valves.
