Here is a question that probably nobody knows the answer to seeing as how everyone wants loud...lol!

I am working on a project for the wife to drive around in and need to know if anyone makes a hiflow muffler that is whisper quiet? Do any even exist? This is going to be the ultra sleeper project.

 

Mufflers don't really restrict exhaust flow a whole lot, so whatever sounds good to you. Obviously stock would be the most quiet, after that Dynomax and Summit turbo mufflers are pretty quiet with just a deep tone. Magnaflow is a bit louder but still pretty tame. Youtube some exhaust vids and find something that you think sounds great.

 

From what i have seen , the dynomax superturbo muffler is really quiet, yet, flows pretty awesome. Somewhere in the neighborhood of 385 cfms.

 

Deffinately!

 

I bought a Dynomax Ultraflow (Stainless Steel) last year and am very happy with it. Louder than stock but not too much. Awsome flow numbers, too.

 

i used to have a dynomax super turbo i can tell you from experience it was the smoothest most quiet aftermarket muffler ive ever bought.

 

Dynomax is really starting to grab my attention...about time to reinstall the cat-back and get rid of this dumped thrush welded muffler, lol...I need some peace and quiet!

 

i have stock and its really quiet...but i also have a 2.8

 

I had the dynomax super tubo catback and its just what you're looking for!!
