I just installed a Dynomax Ultra Flow cat back exhaust on my '08 Silverado 5.3. I like a little rumble but at 46 years old this is just a tad loud for my liking. I love the note,just need to mellow it down a little.

How about installing a Vibrant 18" bottle resonator before the muffler? or

What about installing a Dynomax 18"-22" 6" round ultra flow muffler before 24" current Ultra flow muffler. I have room for that.

Only room I have after the muffler is for a 10" case bottle resonator.

Open for suggestions
Thanks.

 

I tried adding resonators on my GTO and it did not do diddley squat. If you have room to add a 18" Dynomax muffler in front of the existing one, that will probably be your best bet.

 

Thanks for the info! That was helpful. I will scratch the resonator idea.

 

Any clue which one of the following would tone down the most? This is all I have room for.

A bottle type resonator will make a very small change. The ultra quiet resonators I used made a substantial change and are small (package easy). Good luck!

 

Awesome info, I appreciate that!

 

No problem. Post up some before and after videos. Always cool to see and might help someone out down the road. Good luck.

 

I noticed you installed the Ultra Quiet resonators in the tailpipes. Would you think installing one of these before the muffler have a simular effect?

 

Hard to say. I'm no expert. I had feedback in other threads saying it doesn't matter and others saying to put it behind the muffler.........

For what it is worth, I "believe" I've seen them both ways from the factory so it probably doesn't matter.

Maybe someone else will post up....

 

I will let you know in a week or so. I just ordered the Vibrant Ultra Quiet Resonator and plan on installing it in front of the muffler next weekend.

Thanks again for the info!
