Solution for B&B Exhaust Drone?

[XfireZ51]

Just a long term update. Last year the DynoMax muffs had pretty much become a boom chamber. We opened one up and the insulation was totally carbonized. This time I decided to go w MagnaFlow muff w almost identical dimensions. Al moved the NPP valves over to these new mufflers and we made one small but I think important change whichis to extend the tips beyond the rear valence panel by ~ .75?. The MagnaFlows are of better construction than the Dyno and w valves closed u get a much mellower exhaust note. Valves open is significantly louder but even then more tolerable than the DynoMax.
I am thinking of trying this next. My gf has pretty sensitive hearing. Anyone have a comment on Block It?

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

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?

Two resonators?

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 💯

Yes, two resonators (one for each side) as each is a single pipe. If you go to the link in my last post you'll see exactly what I'm referring to. This Is the same setup as Phil just a different brand.

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

Do you have a link to Phils setup?

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.
