Mufflers

[Nacho-RT74]

Here is a vid of my new exhaust system, headman headers, 2.5 Dynomax ultra flow, and a universal summit x pipe. I think it has a burly but not screechy tone. It may be too quiet for some peoples tastes though, it does get loud after the first couple trips out.

what's that one ? I mean the PN ?

i ran 3 inch flowmaster 40's through headers for a long time. they sound great, perform great but if you are building a car to cruise then i would go with a different series. the car was no fun to drive after 15 or 20 minutes. you had a headache from the sound and could not hold a conversation with the guy in the front seat. you literaly had to scream at each other to hear anything over the mufflers. 

i changed over to the flowmaster 50 series suv mufflers. they are incredible. car runs great on them, no issues with performance, they have the flowmaster sound but are also unique as well. the cruise levels are very mild and quiet, virtually no drone (below my cruise rpm), and when you stand on the throttle they get nice and loud.

here are a few videos, the 40 series banging gears is with the windows up, the 50 series suv test drive is with the windows down.

yes those are exactly my thoughts about 40s...

should it be some diff between SUV and Delta flow what you are aware ? beside the thick since I remmeber on specs SUV are thicker, I mean about the sound

[c00nhunterjoe]

the suv's are quieter then the delta flows, have a little different tone and the case size is longer and taller then a delta flow. might be longer, not sure offhand. the 50 series suv is a large muffler.

My flowmaster 50's are too loud.  Looking forward to some Dynomax Ultra's to fix that and increase flow.  Already have the x-pipe.

After switching from 40's to Pypes violator series ive been very happy. No annoying drone!!

They seem pretty quiet at idle to me, but really wake up under some throttle.

Ill try to get a higher quality video soon. Damn snow!

Frank, I was under the impression that your car was still in Mass.  Are you waiting on me to get the chunk to you so you can get the 8.75 in there.  Let me know and I'll step up my program a little.  I really thought it was getting body work done at Chuck and Blair's still.  My bad.
Mike

And my vote on the mufflers is Dynomax all the way.  Flowcrapsters are restrictive.

[Nacho-RT74]

what Dinomax model under the requirements I'm searching ?

and Frank... what specifically are those ?

[FLG]

Mike, you have a PM!


Nacho,

They are made by "Pypes" and they are the "Violator Series" mufflers.

Im working on getting a better vid, only have the one i posted and this one

As you can see..under some throttle you can hear em...but when i let off there is really more wind from my bad door seals than the mufflers. If you listen till the very end you can even clearly hear my buddy who was sleeping in the back say "That woke my a$$ up"

[Nacho-RT74]

visited their website and wow, is a good option too.

How much cost at your dealer ? Summit have them on $59, Racers too ( street pro on $46.5 )

Jones are on $40

[Runner]

Yes, Flowmasters have a drone at 1800 RPM's....This is only if you are running 2.97 gears at 65 MPH....If you have ANY gear in the car at all, you will be above 1800 At cruise anyway IMO...


I

i had 4.57 gears and a 3800 stall and the drone was absolutly terrible.   plus every time i got on the car i had to be scared that i alerted every cop in town.    my wife wore ear plugs in the car and we couldnt even carry on a conversation.    man im glad those things are gone.

    i now have 3 inch exhaust going into 2.5 inch dynomax super turbos with an h pipe and at the track i use race bullets right off the headers.   the race bullets sound soooo good but our to loud for street use imo.       most of the rest of our cars is 2.5 inch exhaust into summit turbos , they sound decent, the dart has 2.5's into flowtech terminators, they are a little louder than the summit mufflers and have a diffeent sound.   my wife likes them and i think they are ok

A little late to this thread - but I'm wondering why glasspacks don't seem to be considered that much any more.  They're a straight-through design, and sound deep and savage.  (Especially when they dump at the rear axles.)  They still seem like a viable option.  I'd be running them that way if I could stand to butcher my tail pipes.  But I can't - so I went with the round style of welded ultra flos.  Based mostly on what I learned on this site.  I needed the mufflers to be as minimally restrictive as possible because I'm not running headers.  The flowmasters do sound tough in those clips though. 

[Nacho-RT74]

not late yet...

It sounds like you are looking for something slightly better than stock...Something that is quiet when it should be, but can turn heads when you want to get on it...

I'd suggest you run some Dynomax Super Turbos.  These are the old standard and sound like they fit the bill for what you are wanting to do and most importantly they will not break the bank.

There tend to be 3 camps to muffler subjectivity:

1-Flow (ple that care about cfms and HP and could give a care less if that is 2 db less than open headers or makes a big hyd cammed 440 sound docile...whatever makes the car faster on the track is ideal).

2-Loud (ple that put overall performance and ETs on a backseat to sound...and in this case they want it loud...the louder the better).

3-Not too loud (anyone that says this should just stick to stock type mufflers or something along the lines of the dynomax super turbo...the last thing you want to do is spend $$ on a set of mufflres that you are going to hate driving around with).

Personally I value performance with a particular partiality to the louder side of the spectrum    It works for me and it is what I want and expect from what I have.  Should I ever acquire a Mopar, say a Slant Six 66 Barracuda, that doesn't fit the bill for what I think should sound like a fire breathing monster, I will go with something deathly silent.  It all comes down to the individual and what they want and will tolerate from their exhaust system.  There are always trade-offs and the important thing is that you get it right the first time so you don't sink unnecessary money in the project.

Based on what you've said I would strongly suggest you at least consider the Dynomax Superturbo.

yes you got it

Then you should look into Dynomax SuperTurbos 

[Nacho-RT74]

Ok... there are some that I like a lot ( Jones, Dynomax super turbos or thrust turbos, Violators by Pypes, Flowmasters 50 ). I have heard with attention all your advices and I liked several options... I'm trying to get first at local market first. There is one dealer offering the Raptor series by Flowtech... what do you think ?

they are on a more less decent price for the local market ( I can get allmost two of these by the price the thie... I meant, exhaust shops    sells one Flowmaster )

[R2]

How big of a difference do you guys think between the Flowmaster 40's.,,,,,, and the 50's,,,,, ??

[R2]

anyone ?

Nacho heres a quick video i made last night.

Will do another one soon. Was playing with the new phone (DROID, awesome btw) and uploaded it straight to youtube. Worked out well, you just cant see anything LOL!

Think you get a better idea of the sound, though not quite. I will be recording one on saturday with in nice hi def.

I have used a variety of mufflers on a variety of V8's so it's hard to give a direct comparison. I have Magnaflow's on my 73 Vette with a 383ci Stroker. I have Flowmaster 40's on my 66 Buick 300ci. I have Edelbrock SDT's on my Olds 442 with a 400ci. On my 68 Charger with 470ci Stoker, I have Accurate's "Hemi" mufflers. I have Dynomax on my 65 Mustang, but it's only a 6.

For me, the best exhaust is something that has a powerful bark when I stomp the throttle, but a mellow, quiter "growl" at idle an cruise. I'm very sensitive to higher pitches or tinny sounds. A mellow, low grumble is the best as far as I'm concerned. Any exhaust that sounds good is going to have some drone. The issue is volume and resonance. Frankly, I don't mind a little drone at idle, but I wouldn't put up with something too overpowering.

Without a doubt, my two recommendations are the Magnaflows or the Accurate HEMI mufflers. Both of them are awesome. They have a TON of presence when you stomp the throttle, have a great idle sound, but are mellow at cruise. The HEMI mufflers have a little bit more drone, but the frequency doesn't bother me. The Magnaflow drone I find to be more mellow. But I would rank #1 the Hemi and #2 the Magnaflow.

The Flowmasters are nice – but Flowmasters are like Torq Thrust wheels. Nobody is going to fault you for buying them, but everyone's got them. They sound fine, good traditional muscle car sound, but they don't have a ton of presence. If you want something a little more mellow, but with some personality, I would actually recommend the Edelbrock SDT's. They are a TINGE louder the Flowmasters, but have a throatier idle sound  - they have a great muscle car sound but are more unique. They are equally as quiet as the Flowmasters at cruise.

The Dynomax's that I've heard are comparable to the SDT's. They're a bit throatier, but have a slightly higher pitch to them which I don't quite like as much.

As you know – all very subjective.

Not gonna lie I jumped a bit. That's a lot of bark compared to the idle.

[Nacho-RT74]

Corellian Corvette... which magnaflows ?, their website is very set to modern cars

mmm hemi mufflers  , never though on that before!

LOL I did like the Flow's-Torq Thrust comparisison... is true LOL, and thats why I wen't far away from those wheels... I'm set on centerlines 915s vintage

( editing... well, Hemi mufllers on $120-150 rate are discarded )

[Nacho-RT74]

dunno, but on this comparision... I choose FMs http://www.youtube.com/watch?v=zgz3x1w71qs&feature=related

50s of course

They really wake up when you get some flow going through em.

does somebody knows about FLOWMONSTER ? I talked about an ebay dealer of this brand talking about my requirements and budget, and he replied me talking about these:
