Well as some of you know already I installed a Dynomax Super Turbo cat-back system on my '03 4.0 SOHC. I was surprised at how quiet it is. Almost down to the stock level. Will it get louder as it gets broken in/ or ages or is it going to be this quiet forever?

I noticed that the muffler has a fiberglass sound deadening material lining the inside of the muffler. Does this burn-out at all?

 

on my old ranger, 3 yrs ago now, the dynomax muffler i had on seemed to have no problems for the year it was on, didnt notice it to get any louder

 

Biggest waste of money for me.. next week im cutting it off and running a mufflerless side exit...

 

Mine never got louder.

 

hmm, well I was hoping to be just a little louder than stock but its pretty close....

 

That's why I got this Dynomax system, cause I couldn't stand the side exit mufflerless exhaust!
I have the tailpipe I used to bolt up to the stock system in the garage still.

 

mine got louder, but thats probably because i put a bigger pipe on the whole way back.
i find it gets a little louder depending on the weather too...or maybe thats just in my head

 

if you want loud...i think flowmaster 40 series is your best bet...

 

Yeah dynomax has always been know for better flow without the noise.... It may get a tad bit louder, but not much...

 

Does the dynomax use the same size piping as stock? I assume stock is 2.25in?

 

^Stock is 2.25 but I don't know the dynomax size, maybe there website will say?

 

dynomax wont get louder.....that is why i got mine.....i like the quiet sound with extra flow...

 

okay then, yeah after I look back at my mufflerless dumped exhaust I like this current system alot better. NO droooooning at all.
