i just purchased a flowmaster 40 and was wondering if anyone has used one,also what are the pro's and cons.

 

yeah, probably most popular. Pro and cons? Just sound i guess...

 

does it help with the slugishness of the 3.slow.lol

 

I've heard the flowmasters are more for sound and less for performance. It's not like your going to get much performance either way from a muffler.

 

i have one on my truck and it sounds amazing!

 

More sound than performance for sure. I had two different 40 series on my truck then switched to a borla proXS, which I thought was a little quieter but more refined sounding with added top end power.

 

i have a flowmaster 40, with duals out the rear, sounds great..have had mine for bout 2years now.. i really didnt notice any performance increase.

 

yup that is good news for me,since mine is also a 3.0 five speed,makes you wonder what the con's of the 40 are.

 

cons: doesnt really do anything for power, ur gonna get pulled over, and it sucks tryin to sneak around at night!

 

so i take it,it is loud,but has a good rumble to it,mine has a 2.5 inlet and outlet,the guy i bought it from,sold it for the noise polution reason.

 

same size as mine... rev it up to like 2100- 2600 and let off and hear that sh*t rumble and pop... i love the poppin sometimes

 

yeah i had one like it before,and liked the way it sounded,so i decided to give it a try on my truck,is yours dumped??

 

nah mine isnt dumped... it actually goes back to the stock pipe after the outlet... thats bein changed to 2.5 inch pipes in early june with a cut-out

 

sweet

 

i have a 4banger and like it. As long as you don't mind some interior drone then you'll like the flow 40 -Mike-

 

i have the 40s with si/si but with a Y pipe to dual out that back. not to loud if u ask me but i have the 4.0L but i has a good sound to it.but i know i got 122.6 decibles on a decible test at the carshow. i wonder what the leagal limmit is for where i am?

 

original has the drone. delta doesnt...

and for the record my truck with a 40 is more quiet then all the ricers that drive by my house with fart cans

 

I have a 2" si/so 40 Delta Flow on my 3.0L with both cats in placed and dumped after the muffler . . . couldn't get any closer to a v8 rumble and sound if I tried. It has the nice V8 rumble at idle, 600-1500rpm range is a steady humm (only con) and then above that sounds like a quiet V8 with a little more rapid rumbling. When engine braking (downshifting) it has a nice and LOW rumble, draws looks down busy streets when I get the muffler warmed up. Overall if you're looking for a deep, V8 sounding rumble, the Flowmaster 40 Series Delta Flow is the way to go!

 

On the 3.0 there isn’t a exhaust system out there that will even noticeably increase your power, so basically its all for sound. The Flow40 is definitely the best sounding one IMO, i love mine.

On a side note, my Original40 has zero in cab drone unless i want it to. And at crusing speeds (40mps and 65-75mph) there is also ZERO drone.

 

I noticed an immediate increase from just my Borla muffler. I have 2.25 piping which helped a lot.

 

well i finally got my 40 installed,it is not loud at all,but it does have a nice rumble to it.
