Are there any mufflers out there that sound just like the stock ones do but are louder? I like the stock sound but would like it to be a little louder.

 

Yeah...Get you a flowmaster 80 Series muffler...

 

Anybody else have any mufflers to fit in this category?

 

dynomax ultra, cheaper than the flowmaster

 

I'ld prefferably use a spintech over a flowmaster. I've had both and the spintech is better sounding and less drone in my opinion.

 

Flowmaster is NOTHING like stock. Its louder and obnoxious. What kind of Flowmaster have you been listening to???

I would recommend the Dynomax for a stock sound. Magnaflow is also good but sounds different than stock.

 

Magnaflow has a unique sound to it. Magnaflow were actually made for 4th gens, thats why Magnaflow doesnt make a kit for our cars. Check out my sound clip in signature.
I also concur that Dynomax is stock sounding. I had Dynomax before I went to Magnaflow.

Check it out

 

I agree, for a stock type of sound go with the dynomax kit. It's cheaper than most others and it's about one notch louder than stock.

 

i got a 3'' kit with flowmaster 80* and its too quite. and i dont even have a cat

 

Well IMO, being you said you wanted to keep it 'stock sounding but louder' I would go with a Dynomax SuperTurbo. They are just slightly more dBs than stock and have a sweet burble.
However there are alot of different variables. Like weather you have a catalytic converter or have a testpipe, diameter of intermediate pipe (2.25,2.5 or 3"), headers or stock manifolds and believe it or not, the tips and exit.
Stock has a few different pipe diameters dependent on year and motor.
If you have headers, then longs and short tunes will differentiate the sound.
Stock the tips/tailpipes are usually (2) 2.5" (unless a V6 car) and point downward. Which downward IMO tends to make the sound more burble than straight.
I did a D.Max SuperTurbo on the TA back when it was a 305. It was the full catback replacement kit. It was a 2.5" intermediate pipe with dual 2.5" outlets. This was just like stock for my model. Tips faced down angle like the stock 1986 exhaust did. With the converter on it, I had just a little louder yet more pronounced tone. It did get slightly more louder as it broke in, but not too much. I got many complements on it. I removed the cat (gutted it) and it got I would say 10dB louder. Which was very noticable, but the exhaust still had a reasonably stockish-mod sound. No resonance or drone inside. The cat had a tinny sound from being gutted which I hated. I later had a testpipe made and it was much better. Next I did Headman 1 5/8 headers (shorty) and y-pipe. It got louder and more header-like. Took away from the stockish sound, bt the levels and tone was reasonable.
I would like another DMax ST, but now I have a 3" intermediate pipe and they dont make a ST with a 3" inlet.
Now I have a way louder 80-series Flowmaster (the stock replacement model for the F-body by them is the 80-series), a 355 with stoudt cam and SLP 1 3/4 headers.
Ive heard the 80-series Flows on a stock with cat 305TBI B4 first hand. Its much louder but not too unreal. It doesnt have alot of resonace control. Meaning inside the car you hear it..especially cruising. Kinda like a drone. Also has limited control on the deacceleration pop-pop sound.
Magnaflows Ive heard are not too loud, but the tone isnt stockish or pleasing IMO.

 

What, are you deaf? Flowmaster without a cat should be way loud.

 

Heh, we might just be getting old… one of my favorite exhausts ever was basically headers, 2 high flow cats and straight 3” pipes with no mufflers on a mild 305. I have another 305 project car now and I’m wondering what I would think of that setup now (it’s been about, wow, holy ****, 15years since I did that the first time around).

FWIW, dynomax or headman stuff is going to sound the closest to stock but louder…

 

I run the Dynomax Bullet on my single 4" and Love it.

 

Flowmaster 80 crossflow, no cat here. Much too loud for my taste.

Had dual 3" bullets on the '57 for awhile (a couple of months). Had fellow racers looking under the car to see how I was getting away without mufflers in the mufflers-required class we were running in. Also had to drive with an egg between my foot and the accelerator pedal when driving home at midnight after a night of racing. Certainly not even close to a step louder than factory stock.

 

Stay away from the GMMG if you want a quiet exhaust. This thing with cat is louder than my Flowmaster 80 without cat.

If you want the stock sound, but slightly louder and want the performance boost to go with it. I'd keep the stock muffler but put on some headers. Not easy or cheap. But should give you more HP than any muffler will give you and also sets you up for down the road.

 

I'm going with a hooker aero, I heard sound vids from other cars and it sound nice. not to loud, just right, seems like the best of both worlds

 

I liked the Hooker sound myself too. Im going to keep ly 80 Flow until its dead tho =) But the Hooker is prob my next one

 

I have an aerochamber on my truck and love it. Nice and deep, healthy sounding outside, almost not there inside. I’m considering a 4” on my TA…

 

Dynomax Superturbo for close to stock sound definitely..

 

anybody heard the flowmaster super 40s?

 

I have a Super 40 on my S10. Its a 2.5 in/2.5 out and the truck is a 4.3 It is different on the V6 than the V8, but IMO its not the quietest Flowmaster but its far from the loudest Flow. It was a reccomended muffler for a smaller cube motor by a few sources. On the truck I am happy with it. There is a member on the S10 forum I moderate who has a 4.3 Silverado. He just created a video of the different muffler setups he tried. One is the Super 40, one is a Magnaflow, one is a Super 44 and the other I think was a Dynomax. I can get you that link if you want. Its a 4.3 motor, so its overall sound is different than the V8s. But it would give you a dB differentiation to compare it to.

 

Super 40’s and flowmasters on v6’s and 4cly are sort of unique situations. I generally hate the sound of flowmasters on v8’s, but the new (relatively, compared to the rest of their line) super 40’s sound completely different than the rest, they’re lower, deeper and more mellow than the rest, they don’t have the metallic raspieness that the rest of the flowmaster line has.

Second, as much as I usually hate how flowmasters sound on a V8, I think they sound kind of cool on smaller engines.

Mikz… I’d love to see that thread, a 4.3L, having the same port layout, geometry and most parts of a 350 should sound a lot more like a small block than most other smaller engines…

 

i was thinking about this one: http://store.summitracing.com/partde...2D2816&FROM=MG

 

man............if the flowmasters are loud then i definitely dont need to go with the glass packs i was planning on.

my neighbor has a magnaflow on his 92 bird. its summit racings PN MPE-14329. and it has a mellow sound at idle and a great sounding rumble when driving down the block.

isnt dynomax and magnflow the same corporation? or is it Trush and dynomax?

 

hahaha whatever you do. dont go buying a cheap cherrybomb muffler.
thats what i did. they sound like crap. pure crap.
i only got it because i needed a muffler and it was really cheap.
and i still have it on my car

 

It’s different, me being one of the people generally objecting to them, I think I’d more accurately put it as most flowmasters are noisy. I’ve run a 305 with headers, 2 high flow cats and 3” pipes, no muffler at all and was very happy with how that sounded, and at one point looked at the same 1500 3x, that was really a piece of junk, but it’s glass pack exhaust sounded soo good, even my wife liked it.

Walker owns an oem division (lots of the stock stuff on cars is made by them), commercial, aftermarket as well as dynomax, thrush, and some others, the cool thing is that if you know your way around their catalog and part numbers you can often order performance parts through non performance suppliers and in some cases get parts much cheaper under one name then the other

the flowmaster 80 dont reli sound much different than stock. Its deeper and you dont hear it inside the car which is a huge plus

My Flowmaster 80 with the stock I-pipe and a gutted cat idling a tad high because it was still warming up.

I think it's pretty loud sometimes, other times I think it's way too quiet. Depends on my mood. Has a nasty drone at exactly 60 mph (Around 1700 rpms) and the whole car just starts resonating... I'm used to it now and dont even notice it anymore, but on 55 mph roads I stay right on that drone to go 60mph, since I dont have a cruise control.

I think how loud it is depends entirely on whether you have stock manifolds or headers. I heard an 80 on a 350 TPI Formula and it was deafeningly raunchy, dare I say, trashy log truck loud as I was following it down the road. I guess mine may be that loud on the highway from behind, I dont really know.

Normally I think it's a little too quiet... But it does sound pretty good. I like a raunchy sounding exhaust. Makes the L03 worth having.

 

Again, you must be deaf. Flowmasters are LOUD and DEEP. They resonate inside the car when you hit their magic RPM, around 2000 rpms. They may sound fine on a stock car, but once you start opening up the rest of the intake and exhaust with performance mods, Flowmasters become annoying, in my opinion.

 

I was looking at a hooker catback just because every other camaro or firebird has the flowmaster 80. And they all sound nice at idle, but get sloppy and drone while driving.

However, I started looking at the flowmaster again after I heard one on a firebird like mine that was a 5-speed. I think the manual tranny really makes a huge difference in the sound, and it sounds sick when you let off to shift, then get back on it.

Im sure it will drone alot inside the car even with a manual, but I can deal with that. My old 3.1L 1995 monte had a blown out cat, 2.5" exhaust, and dual IMCO Pro mufflers (knock off 40 series that were $20). Let me tell you, the 60* v6 really drones at about 2300 RPM. OMG I used to get the worse headaches after a trip. But after a year, I didnt notice it at all.

So I think a V8 drone will be not so bad. At least it will be pleasing to the ears!

 

Well compared to my friends bimmer (hes got the 40 series) my car isnt loud at all. I guess when i get the headers installed itll be alittle louder

 

I've never heard a Flowmaster that is anywhere near loud on any mildly built car or engine. The exception being a dedicated drag car with a huge cam and high flowing heads with a muffler at the end of LT headers. Nor do I think they have a deep tone. They have got to be one of the least deep sounding mufflers that I've heard. I have a Flowmaster 40 series with 2 1/4" x 3" exhaust without a cat on my stock LB9 and I can still carry out a conversation with any passenger at WOT barely having to raise my voice. No drone either. But then again I guess the fact that I work at the drag strip might have something to do with it. To me, anything over 93 dB at 100' away is loud. anything over 103 dB is earsplitting. my car is right around 85 dB.

 

Do flowmasters die? I mean, its all chambers and baffles. My flowmaster Delta Force single chamber's werent cheap, and I dont want to have to buy them again.

I don’t know what he meant by that, but flowmasters do go through a sound change after you run them a little and thein insides get coated and baked some. Eventually they will rot out also, just like any muffler that isn’t stainless

 

I'm pretty satisfied to Flowmaster quality(aluminized versions)First flowmaster which I bought at 1991 lasted only four years.That was non aluminized 40 series muffler.Second one(aluminized 50 series) that I bougth after first one at 1995 has lasted to present day.Now it is time to new muffler,trying to figure muffler(3"offset in and 2x2,5" centered out opposite side of inlet) that has max flow capacity and quiet enough....I'm getting old...

 

True duel pipes running down 1 side,(2) 1 chamber flowmaster racing 6 inch long mufflers,DR Gas X PIPE,4 Inch tips,Its VERY loud,so dont go that way,unless you want to wake up THE WORLD,LOL Sounds like a NHRA drag car!!!
Dynomax,Magnaflow,Walker,are all about the same,not to loud,but not quit like stock,they all sound good.

 

Gary Sanders, you dont happen to have a clip of your car with the combination listed do you? I looked at your sig and noticed that we have to nearly the same engine combination. Except the 355ci I'm building is a solid roller Iskedarien cam, with Dart Iron Eagle heads. My pistons are 10.8:1 TRW's, and my crank is a SCAT forged. Rods are Eagle H-Beams. Would be cool to hear my engine before it is even in the car.


Thanks,
Max
