What about the addition of mini "bullet" muffler before each of the current mufflers? They are very inexpensive.
Here is one example by Dynomax: https://www.dynomax.com/mufflers/rac...round-623.html Here is a smaller one from Total Flow: https://www.totalflowusa.com/totalfl...inner-diameter

The new B&B is not in my goals now. If I upgrade my exhaust it will be a 3" titanium system to save weight.

I would just go with the Maximizer exhaust to hook up to your headers.....It should bolt right up, but I would have it all welded in place instead of using clamps.
Ebay has ZR-1 Maximizer exhaust systems on sale for like $250. That is an incredible price considering they were $1000 last year. |

After calling a few exhaust companies and looking over Phil's system, I think the easiest and least expensive option overall is to add in two resonators between the x-pipe and the mufflers. This company specifically makes their resonators to eliminate drone depending on application and they match the B&B 304 stainless: https://flasharkracing.com/products/...4-in-diameter?

#IDTS You will be better off #IMO with a used a C4 LT4 exhaust cat back system (2 3/4" vs 2 1/2") and replace the LT4 resonator with a x pipe ane with the x pipe as close to the engine as possible. #size does matter 💯

A used LT4 exhaust would be difficult to source and would be far more expensive.

I have a LT4 system on my car.. I have 2" headers into 3" cats in to the LT4 system. Honestly, if you did anything to the LT4 system it would be to replace the mufflers to give a bit more growl. but overall I have no resonance in my car.
