Looking at that chart up a few posts I am shocked that so many of those mufflers are actually louder than the DYNOMAX Ultraflows.



Yep, look at the flowmasters; louder AND more restriction! Pretty easy to see why all the PSMCDR cars are using Utraflows.

I also see that the 17288 crimped muffler is quieter than the welded Ultraflow.
