Magnaflow Muffler Part #/Opinion

I am thinking of getting this muffler - http://www.magnaflow.com/02product/shopexd.asp?zone=main&id=8020 . I was looking at this one because from what I know the bigger the muffler the more sound deadening it can produce. I was also going to remove the second cat and install this in the stock postion and just dump the exhaust over the axle. What do you guys think?

I was also wondering if the stock pipe was 2.25in?

 

do yourself a favor and get the dynomax super turbo good sound and response part # 17747. the pipe size is 2.5

 

I heard the baffled mufflers resonate sound into the cab.

 

no prob outta mine, i also have dt headers and nice solid rumble. the sound is pleasant and not intrussive, just enough to let you know its back there and others to know its not stock!

 

vt when did you end up getting the dynomax?

 

sat morning, came from summit racing

 

nice did you research it after the suggestion at all? I found reviews all over the places but all in all, pretty good. How much?

 

ive looked at everything out there man, i had the dynomax before but had to take it in for warrenty work and they wouldnt touch it until it was put back to stock. so i changed it back temporary im thinking about the bosal also. the dynomax shipped to my door was 68

 

i'm assuming bosal is another muffler brand? Did you weld it on for bolt it?

 

clamped it for the time being, the dynomax # was 17749 theres another one ive been checking out its a dynomax ultraflo part # 17288

 

hmmm intriguing. Did you notice anything with the muffler on paired with the DT LTs?

 

slight difference, personally by the stats on the site the super turbo is more restrictive then the ultra flo by twice as much

 

ya honestly i couldnt care less about sound, I just want something that breaths better

 

the ultra flo cost more but i would say thats what youre looking for

 

I was looking at the Dynomax Ultra Flo and I like the 17559. Its 20in long, which should be awesome for sound. I want a straight through design so its easy to put in place of the stock one.

 

i have that same magnaflow muffler on my truck, i cut the stock muffler off and welded the magna flow on with some straight pipe and then used my old tail pipe, its so loud i have gotten pulled over twice already for it, i would probably go with a complete system instead unless you dont mind getting pulled over.

 

Do you think an Oval shaped muffler would be quieter? Like this - http://www.dynomax.com/ecat/pdfs/ultraflowelded.pdf ?

 

no typically the larger the muffler the quieter

 

Thank you for the help I have narrowed my search to prossibly this muffler - http://www.magnaflow.com/02product/shopexd.asp?zone=main&id=7998 . I think I would prefer a MagnaFlow.

 

honestly i wouldnt go with the center in/output go with offset in and out here check this one out! this is what i recommend
