what are the loudest sounding mufflers?

[THE CHARGER PUNK]

i am wondering what are the loudest sounding mufflers? i want something a motorcycle loud,any ideaz?-MATT

[Troy]

Why use mufflers?

Troy

[Dans 68]

Maybe he means the loudest, "street-legal" system available?

Dan

[Silver R/T]

street legal hmm well I know loudest would be Dynomax bullets but they wouldnt be street legal on 440 as it would be too loud

[69bananabeast]

I dont know about the loudest but flowmaster 40's sound good. sometimes my 318 sounds almost as good as a 383. Cant wait till I get the 440 in and let it rip .

[ClassicStack]

This is old technology but here it goe's. 12 inch glasspacks with headers. But I don't know if 12 inch glasspacks are street legal. I know 16's are. But 12's are pretty damn loud. Or you could run open pipe. This is what I used to do when I was a kid. Header's to exhaust cutouts with a cable to open them from the inside of car then from exhaust cutouts to 16 inch glasspacks when not running open pipe. Or you could do the above with Hemi muffler's or any muffler of you choice with the headers and exhaust cutouts. With open pipe it's loud enough to rattle window's, door's, hearing damage, knock dishes's of the shelf and get you car toed by the cops. IM VERY SERIOUS ABOUT THE LAST SENTENCE! Last thing you want is hearing damage and you car toed away by the cop's.

If moderator's feel this is to much info please feel free to delete this post. Im just giving my personnel experience about what I used to do.

[69bananabeast]

im gonna have electrical exhaust cut outs behind the 440 and  in front of a flowmaster 40's with  X pipe . The other day I Started to pull the 318 and once I got the headers off and I started her up . A couple of the neighbors came out and thought something fell on me 

[firefighter3931]

Don't put flowbastards on the car unless you want to slow it down.

[69bananabeast]

well back in the day when i knew nothing about performance or being a mechanic I bought the car out of california and brought it here to texas. the exhaust dumped off to short . so I took it to a muffler shop and they did everything I dont know if it had flowmaster to begin with or not thats what i've always had.   Also does any one know how long a 440 can run open headers safely?

[Runner]

race bullets are nice and loud, nothing id want on a daily driver but they are loud

[79JON]

I have a mild built 318 with 2.25 full exhaust with Flowmaster 40 series.   I kept the manifolds on there to keep the exhaust leak from happening.   I also have a H pipe which gives it an extra rumble.  I swear my car sounds like a big block driving around and people always think its a 383, 440.  And they get shocked when I tell them its a 318  HAHA.

[CFMopar]

Dynomax ultra flows. Quiet untill you floor it. Plus its a straight through design not like flowbastards.

[Mopared]

Race bullets got my vote.  Saw a video of muscle car with them.  sounded like open headers.

[my73charger]

Whats up with that Ron?  I have flowmaster 40'2 and I love them.  They are a straight shot front to back muffler and they sound great.

[MoparYoungGun]

Flowmasters use chambers with baffles in them to absorb/reduce sound. The baffles restrict the flow of exhaust which inturn hurts your performance. The Dynomax Ultra-Flo uses a straight threw design with packing to absorb/reduce sound. The Dynomax's don't hurt your performance because there is nothing to restrict your exhaust flow. Personally, I will use Ultra-Flo's on my Charger.

My dad owned a 68 charger with boat exausts that came out in front of the tires. I havent heard that before but he said it was sweet.

Actually, flowmasters are quite restrictive. If you define sound as a measure of performance then maybe the flows are worthwhile but only if you want that type of sound....personally the resonating drone is quite annoying....my opinion of course.

How restrictive are they....a member on this board dropped 6-7 tenths in et by taking off his "fflowmaster" exhaust system.   That's not the first time i've seen that happen either. I also know guys who run full exhaust systems on their cars and run faster than on open headers. These are x-pipe/ultraflow combos with tailpipes.....the full deal. These aren't slow cars either....630hp and mid 10's at 128mph....with the "right" exhaust system in place.

Thanks for the insight.

Thanks for the insight.  

Here's a flow chart comparing dynomax ultraflows to some of the other popular mufflers out there in the marketplace.

[steves66]

Which one of these mufflers is louder, the Dynamax Ultra Flows or the the Flow Masters 40's?

[CFMopar]

probley the flow bastards but if you dont care bout going fast put them on then   

[steves66]

Don't hold anything back, say what you really mean I plan on the Dynamax Ultra Flows myself. I have no interest in slowing my car down.

[CFMopar]

Thank you I will

The American Thunder 40 Series is the most aggressive sounding street and strip muffler in Flowmaster's product line. The 40 Series will generate extreme interior resonance within the vehicle. If you want to really hear your exhaust system inside as well as outside your vehicle the 40 Series is for you.

  Huh. I was thinking thrush turbos would be good. Glasspacks sound too loud ( not good with a 2 bbl 318 though... )

Should say:
The American Thunder 40 series is the most aggressive power eater muffler in Flowbastards line. The 40 series will generate extreme interior resonance so much so that you will want to shoot yourself at idle. If you want to add .5 seconds to you 1/4 mile and be so loud that you get tickets at every corner the 40 series is for you.

Flowmasters can actually do a pretty good job of making your nice wedge motor sound like a Chebbie! 

On a Dynomax set-up, has anyone used an Ultra-flo up front and a race bullet out back as a sort of resonator?  What would that sound like?

I haven't but have heard of people who have. I would tend to think it would sound the same just a little quieter. People also have used Glasspacks as resonators too.

[426wedge]

I used a set of Magnaflow mufflers on my 440 Cuda. It was very loud and had a really deep pitch to it. The car had an angry sound to it. Don't use without tailpipes!!!!!!

[brian_charger74]

I run Cherry Bombs on my 340. Let me tell you, it is really, really loud. Do even think about using a cellphone and at 40-45 Mph your teeth will rattle in your head. I don't really like the sound but, if you want to loud legally they are the way to go. But, the packing doesn't last too long in them and they will get a little louder with time.

[CFMopar]

The packing last about 20 mins I dont think their legal once they've worn out. I got rid of my cherry bombs cause the droning sound killed me....

[myk]

I have to admit that I like that "Flowmaster" tone, but I like the fact that I probably run faster with the Dynomax's even more.  It's times like this whenI have to remind myself that having a head-turning exhaust is for the ricer crowd; head-turning speed on the other hand is for folks like us...

[MTPOCKET]

Red cherry bomb glass packs. Bolt right to the headers no stright pipe.

[73rallye440magnum]

im currently running turbo mufflers, no tailpipes yet (project car, it hasnt been driven) ill get tailpipes, drive it for awhile, then probably put some glasspacks in coming out infront of the rear tire. im asking to get pulled over. i have stock manifolds.

[KMPX2]

I run open pipes on one of my Harleys go for it.

[charger72]

my opinion is that you stay away from dynomax. I had them on my 72 when I did the exhaust and they blew up a day later. It looked like someone grabbed them ad twisted cause they collapsed inside. Plus they were pretty quite with the 318 and duel exhaust with h pipe. Now I have flowmasters with series 40 open chambers, and it is deffinatly loud.

[CFMopar]

loud... but slower.

[ChgrSteve67]

 

[derailed]

After reading what Ron said, I would say the Dynomaxes are the way to go and if you feel they arent loud enough you could always install some header dumps for the moments of loudness which you would probably get tired of. That way you have the best of both worlds.

[CFMopar]

 

Trust me loudness gets boring after a while when you cant hear the person beside you.

[cudaken]

 You need loud mufflers, you need a engine! Something loud to me is easy picken's.

When you are nasty, people need to cock there heads a little to hear the nasty ass lop. But loud exhast is cheaper.

Headers and header mufflers and no other pipes is the way to go if you want your head to hurt and want 5 counties and cops you are coming.

Long time ago I was young and broke. My Ruuner was not stock and only had Header mufflers for exhaust, Thrush I believe. I drove her to Vothech school and all of the guys where asking about cam, carb and other stuff. One of the guy's in my class walked over and but his hands over his ear's! That is when I knew it was time for a new exhaust system. Brad was born deaf, never heard a thing in his life, but could feel the 68 Runner exhaust! Now that is loud. Not top fule loud but loud.

My self, I like quite now unless it is the Stereo.

[ChgrSteve67]

I'll second that.

[dd44068]

I have 40 series flowmasters on my 68 charger r/t they are ok but between like 25 and 50mph they can be annoying at times

[RT DAVE]

Do they still make "Purple Hornies"?   I don't really want to know, just wanted to type "purple hornies".   

[Lowprofile]

Actually wasn't it TK73 that was a big fan of Purple Hornies?

Anyone ever used glass packs as a resonator after a muffler?

[deathcharger71]

i run spintech mufflers on my car, not a lot of people know about them but they are pretty sweet. sound simialar to flowmasters but have no interior resanance...hated the flowmaster on my jeep. mine are pretty loud, cop pulled me over told me they were a little too loud but let me go with a warning. but they make a muffler thats meant to be loud with catalytic converters and if you run them without cats its supposed to be ground pounding! i almost got them but i decided to get cut outs for when i really want to piss off the neighbors 

[Ghoste]

That's so funny because last night, I guy I know with a 72 Road Runner was pulling out of the parking lot and someone beside me said something about what a nice job he did on that car.  My reply was, "yeah, now if he'd just get rid of those Chevy frap mufflers."  I was then informed that he had just put new Flowmasters on the car last week.

[plum500]

I've got Flowmasters -- as I'm gettin educated on here, I'm thinking that's the next thing that's gonna change... not this year though. ...yikes...

They were on there when I first got it - but with turndowns right after the mufflers. I really liked that sound, but damn restrictions/vehicle inspection forced me to run tail pipes which took most of the nice, um, "open" sound away. Still loud, especially at the right speed...but...

..either way, I do/did recognize that "zone" where the Flowmasters produce an effect I'm not crazy about -- before and after the pipes.

...not to mention, I want that baby to be able to breath....

[Ghoste]

So, at the risk of thread hijacking here, do any of you know why Chevy's sound that way?  Is it a universally desired sound by Chev owners or is it something to do with the way they are engineered?

It's called horsepower...   

[Ghoste]

Well, there's that too of course, but I meant that brappy noise they all seem to make from the exhaust.

[XXSpiralXX]

   Yeah they still make purple hornies, but I dont know anybody who actually uses them. I put generic turbo mufflers on my 72. 2 1/4 in inch with an H pipe. Its a 2 bbl 318 and it sounds pretty good. When I put a better motor in or go with headers itll be nice, but the resonance sucks at about 40 mph.

[GoodysGotaCUDA]

Im running Flowmaster Super40s on my 318. Some people may say 'flowcrappers' or whatever, i like them on my car and thats what matters here 


Crappy quality, but my lil 318 makin noise
