HI,
Just wanted to give a quick review of this muffler since there are a lot of threads about the dreaded exhaust drone from the 6.0's and how loud they can get with a cat-back. First, a little about my setup:

216/220 .560 lift @ 114LSA cam
Volant CAI
Doug's Shorty Headers (stock cats and mid-pipes, 2500HD's dual 3" factory)
Flo-Pro 2505 HD Big oval

My goal was to get an exhaust that would provide a nice mellow deep tone with NO drone. I also needed it to be on the quite side since I tow a TT up in the Rockies all summer long. I decided to go with the Flo-Pro 2505 HD Big Oval, and man does it fit the bill perfect.

It has a nice bark upon startup, then mellows out as it warms up. By the time its warm you can hear the cam lopping around, but not too much. I have to admit it is LOUDER than I thought it would be, probably due to my Cam, Intake & Shorty headers. I do get some cab noise at around 1600rpm but it quickly vanishes as the rpm's climb with my 4.10 gear cruising through the RPM range, it has a nice growl to let you know it�s there, but it�s not raspy in any way. At highway speeds I have to really listen to hear it, which is exactly what I was going for.

OVER ALL: NO drone, deep, mellow, non-raspy, not too loud, direct Muffler replacement for $220 INSTALLED.

 

Video??

Eager ears want to hear it!!

 

Got any installed pics?

 

need to hear video

 

dual or single tailpipe?

 

video or it didnt happen

 

LOL, I'll get a video put up soon, get some popcorn cause your gonna listen a couple of times before I went with this setup I watched as many posts for this muffler on YouTube as I could find, mine is far louder then any of them...

I was also thinking of getting the " Corsa Touring" catback, but couldn't justify spending $1000 for it. Going to put that money towards some PRC Stage 1 LS6 heads with some milling to get me 10.5 or 11 CR.

It's the factory tip, the muffler is a dual 3" out, then goes into a y pipe with 4" pipe out the factory location.

 

So what the heck man? 6 years I've been waiting and still no sound clip!

 

You better freshen up your popcorn, he hasn't been on the site since the day he posted that.

 

I know I just see so many old threads revived everyday that end up with no answers and don't help anybody so I figured I might as well be that guy. Except I will finish this thread for him sometime in the next week, so the next dumb sucker looking for that muffler can finally find the sound clip he was looking for when he clicked this link off the google.



Also I don't eat popcorn it get under my crowns.
