Well just got it installed and am very happy with it. I was amazed how quite it is on the inside of the truck, Its alot more quiter than that 18inch glasspack i had on it. I am working on a video and will post it later tonite. Does flowmaster have a break in period or is it going to stay the same noise from now on? THANKS

 

Congrats. No break in, but soot will settle in cracks and corners but that wont change the tone very much, it'll help make it clearer though. Atleast you have a real muffler on it now haha. Once your bored of the volume start looking into hi-flow cats, or cutting your rears if you do not have emissions.

 

When i had my Original 40 series, around 300-400 miles in, I could tell a difference from fresh, to "broken in" not like a whale of a turnaround though. can't wait for the video!

 

yeah same here. once i drove awhile on the muffler the sound changed a bit. either way you will like it!

 

Did you just replace the stock muffler and leave the stock piping? Or did you replace the muffler and dump it there at the muffler? I'm trying to decide what to do for exhaust myself here pretty soon and can't decide.

 

The setup i have is a single in dual out with the 4 inch tips out the back


Sorry about the quality of the Video
