I was curious if anybody is running the flowmaster hushpower muffler on their 3rd gen trucks

 

I'm not sure exactly which flow master it is since the previous owner put it on but it sure is quiet. The gutted cat is still there so I'm not sure what effect that has.

 

I'm running one of 4 in the nation and was beta testing it. It is a new technology muffler, that has been dynoed with no power loss as compared to a straight pipe. It eliminates in cab drone and harmonics, and has a deep "throoty" sound. I love it...

 

What size is this muffler? Thanks!

 

Do they make it in a 5''?

 

Anyone else had luck with these mufflers http://hushpower.com

 

Im running a 40 series 4" in and out flowmaster on mine, sounds killer but prob. slowed the turbo a hair.
