have any pics of previous setup? We are probably pretty close to the same. I am thinking it’s 30 or 31 front and 38 or 39 rear.
This was the old setup on GTR wheel fenders have been trimmed front and rear on my car so you may not be able to go as aggressive if yours aren't.
20x9.5 F +40mm including spacers
20x10.5 R +25
My incoming setup is 20x9 +38 and 20x10.5 +27 which should sit a couple mm inboard both front and rear from what this setup was.
New muffler delete went on. Have some nasty resonance in the 1600 to 2000rpm range and around the 125hz frequency. Designing a Helmholz resonator now to solve the issue hopefully.

Same here with the interior drone. Let us know how the Helmholtz resonators work out, and the specs of them. I did a little research a while back and IIRC, it looked like you need them to be roughly 2.5" diameter and I think 26" to 30" long.

What you're describing is a 1/4 wave resonator. I've looked into one of those but fitting one is tricky with the spacing available. Your memory serves you correct although diameter isnt as much of a concern as length. A true Helmholz resonator consists of a primary tube and a secondary larger chamber.
My calculations are showing I'll need a 1.5" od tube at a length of 5.5" with a larger second chamber comprised of a 4" od chamber with a length of 6". Im planning on fabricating these snd having them installed in the location of each of the rear mufflers.
