Got me some new Ultra Flo's!---Done with vid's & serious DRONE!! 3-24-12

[Just 6T9 CHGR]

Now do I crush the corners or not?  

[Back N Black]

I have the same mufflers, you won't be disappointed. 

[resq302]

Chris, being that those seem to be lap jointed and welded, I would be worried about cracking the weld if you dent them in on the opposing corners.  Also, are they the same length as the stock ones?

[bill440rt]

Yay!! 
x2 

I got 'em in my '69 also, Chris. Much better than the Flowdeafeners. You'll like them! 

[Charger-Bodie]

Awesome mufflers! If you are asking if you need too dent them for fit? the answer is "No". If you are asking for your minds sake of having them look stock? Then, "No" because they still wont!! 

[RECHRGD]

Yes, you will love them!!!  Nice aggressive sound but not really loud until you mash the pedal....

[resq302]

Sounds like the Magnaflow 18" muffler I just put onto my 07 Ford F150.  I got tired of the truck being too quiet so I cut out the factory 31" muffler and put in the 5x9 oval 18" long muffler.  Fairly quiet at idle but nice throaty sound when it gets to about 2000 rpms.

OMG....hell must be freezing over 

A non-stock, performance part is being installed on Chris' car

LOL bro! 

Brian C., they are almost the same length as the Hemi mufflers I have on there now.... they are 25" total long (the Hemi High Flow's from Accurate LTD are 25.5" long)

Brian B.  yes the question was to crush the corners to make 'em look the part

Basically I wanted something with a bit more tone to them.....plus Im running out of things to change on the car

Nose and wing??

[MoparMotel]

Very Nice! I've been thinking of getting a set. Had Flowmaster 40's put on this summer and the echo inside the cab is getting to be a bit much.

[Just 6T9 CHGR]

ha ha nope!!

The best price I found for them was at StreetSideauto.com

$187 for the pair shipped to my door ($104 each but I had a code for $20 off plus FREE shipping & no tax....)

For reference they are Dynomax #17513 Ultra Flo Welded

[bsakal]

Chris, if you really wanted to have the crushed corners, you could heat them before attempting to dent them. Or send them to me, I can have my buddy cut and reweld the corners. He's been building race cars for over 25 years, builds headers, and occassionally modifies welded mufflers.

I am curious to see if there is a power increase over the Accurate Hi-Flows....

[Charger4404spd]

...plus Im running out of things to change on the car

Me too... thats why Im puttin a huffer up on top

Thanks Brian...but it was more of a joke than anything 
I doubt there will be any seat of the pants increase....Im hoping for more of a sound increase 

Me too... thats why Im puttin a huffer up on top

Sweet!!!

[bill440rt]

So, when will they become one with the Charger?? 

[Just 6T9 CHGR]

When it warms up more to take it to my friends shop that has a lift & a torch.....getting too old/wise to try and replace them on my back in the garage without a torch

[Charger4404spd]

Come on old man, you know you want to hear them. Grab a piece of cardboard (po'mans creeper) and a sawzall

[c00nhunterjoe]

I am curious to hear what they sound like.

Bill- Flowdeafners.....lmao, havnt heard that before....... to each his own I suppose.

I have the Flowdeaf's on my '68. They sound GREAT at idle and WOT. At cruising speed (35 - 45mph), there is a terrible drone inside the car. Makes you feel like your head is gonna explode. Even put some sound deadening mat under the carpet in the rear. Helped somewhat, but not much.
I'm considering swapping them for the Dynamax's in the future.

[c00nhunterjoe]

Not to hi-jack the thread, but which mode is on your car? The make many different styles to suit your needs. I'm extremely pleased with the 50 suv's I put on mine. Quiet while cruising with nearly no drone but loud and aggressive when you stand on the throttle.

[Just 6T9 CHGR]

I had the Flobastards on my car when I first got it in '97...hated the drone & instantly tossed them for the Hemi mufflers....not sure if they had any other "series" back then...

[Back N Black]

This is what the ultra flow's sound like. http://www.youtube.com/watch?v=rkwtlBhWDc4&context=C34f5ac0ADOEgsToPDskKaoPwLlj5hwClfc5jG2dkj

[c00nhunterjoe]

Sounds really good. How are they at other rpms? Sounds a lot like my car

[Wolfie]

stupid question but is necessary to have headers installed as well to get this sound boost?

[c00nhunterjoe]

The headers will give it a totally different sound. Mufflers will make it louder, long tube headers make it angry..... if that makes sense

[Wolfie]

that helps. thanks : )

Totaly different sound on very similar engines. My cam is a littlebigger then his. The headers make a huge difference in sound.



So how is the ultraflow install coming? Will you have before and after videos?

Not gonna get them on for at least a month or so....for now heres a before video

[c00nhunterjoe]

Cam sounds pretty good. Idle speed sounds a little low but maybe its just the camera. The hemi mufflers are louderthen I thought they would be. I anxiously await the update

[Just 6T9 CHGR]

Got the mufflers put on today.

UltraFlo's sound great!!  Definitely a deeper, more aggressive tone

BUT......got me a nice drone back     not too happy about that.   Drones right around cruise RPM 1800-2200 rpm 

Hemi High Flow mufflers....

[resq302]

Maybe it is just me but I think it sounded better at idle with the hemi mufflers.  Although when you gave it gas, it sounded better with the Dynomax mufflers.

That completely blows that you now have a drone. Is your timing right on?

[c00nhunterjoe]

Sounds pretty good on the throttle.

[Rolling_Thunder]

....plus Im running out of things to change on the car

ORLY?     Remember what happened the last time you said that ?           

[resq302]

hmmmm...... me thinks Chris will be looking into a new over drive trans in the future since that is one thing he has not changed out yet.   

[Just 6T9 CHGR]

Its right on for the dizzy I am running.....Don @ FBO recurved it to use manifold vacuum instead of ported vacuum....I wonder if that would have something to do with it??? 

[RJS]

Definitely sounds quieter at idle, more powerful and RPM I like it!!!!
Need another sound bite to be sure though, please POWERBRAKE in your driveway!!!  Ron

[Just 6T9 CHGR]

Not really "quieter" but "deeper"....doesnt have that "exhaust leak" type of a sound anymore @ idle....

PS---no powerbraking on my new concrete!! 

[68r/t]

I had the same problem, sounds crazy but I put resonators on which did get rid of the drone but killed off a bit the idle note so then I put the R/T tips on and the drone is piercing, take the tips off and the drone is gone.
Mines does it in the same rpm as yours.

[1ol72charger4me]

http://www.jegs.com/p/Dynomax/Dynomax-VT-Mufflers/1316158/10002/-1      Has anybody tried these? They are advertised as a "drone free performance muffler". Kinda weird looking insides. Also on sale at advance auto for $15 off. BTW all Dynomaxs are $10 off including Thrush if anybody is shoppin....

Thats what Im hoping I DONT have to do to use these mufflers

Still wondering if the fact that I use manifold vacuum at my distributor as opposed to the stock ported vacuum has anything to do with it
