I'd like to end up somewhere in between where I am now and where Gussie's is, honestly. So I ask the experts out there, will adding a second muffler in a dual exhaust setup quiet the note somewhat, given the reduced flow through each muffler? Or is the opposite the case, that adding the second will just make it louder and more resonant in the cabin?

OR... third option - just Dynamat the hell out of my interior?

Decisions decisions...
Hey vend !

My brother-in-law changed the factory muffler on his isuzu axiom for a magnaflow months ago and he didn 't like ( neither i ) the sound under acceleration and @ cruising speeds just like yours so he swap it out for a dynomax and he love hit although is a bit louder,but not noisy

I know what you are looking for,the problem is our low compression V6 engine,The 3.5L just don't have what's needed to get a perfect so to speak exhaust set up tune.

I personally would love something like how the chevy trailblazer SS or the cherokee SRT8 sounds,but our engine isn't a V8

If you split the two banks and let them run independently each side would flow with less pressure,that's why my VX is quiet @ idle and driving at city speed.

In theory if you replace the OEM muffler for a good high performance one leaving the two exhaust banks meeting @ the Y connection the exhaust flow increases and obviusly gets louder then with the resctricted OEM

Dynomax have youtube videos testing all its mufflers so you can listen to them .
