anyone have sound clips of bullet mufflers on 3rd gens? like the dynomax bullets in summit? reading around in the archives sounds like the bullets flow better.

cant be louder then what i got, my pipe is gone from the cat on back, no muffler just the cat.

kinda thinking of putting the muffler just infront of the axle and then running my single tip back to the bumper, be light compared to a stock setup and i'de hopefully get some lowend torque back.

 

I'd like to see a dyno run that proves no catback decreases torque becuase I don't think its true. Run bullets before the axle may decrease ground clearance depending on location. I'd put it past the axle just becuase there is so much room there. You'd only be saving a few pounds really. It'd definitely be quieter in the car than your current setup.

 

Nothing flows better than a bullet! You can almost stick your arm right through one and they sound great!

 

A lot of people say the bullets are too loud, I had an ida, will it work?

Basically, put 1 bullet at the stock muffler spot, put a U at the end, hooke it to another bullet, so ther are 2 bullets side by side in the stock muffler location, then run the tail pipe out of the second bullet out the right rear.


So, would 2 bullets inline be quieter than 1?


If you can't picture what i am trying to say, it would look kinda like the chambered exhaust, at least in terms of muffler location.

 

Im running Hedman LT's with 2.5" duals. I am running the bullets and the dump just before the rear. It is not "that" loud with normal driving, but you can sure hear them at WOT.

On the 3" version, you can drop a pop can straight through it.

 

2 in series should be quieter than one.

However, I wouldn't go about it that way. Put the first bullet where the cat normally goes, and another where the stock muffler goes. The pipe volume between them will help in the quieting process. If you still have a cat, then one in place of the stock muffler is probably sufficient.

I haven't used a Bullet or Bullets on a 3rd gen, but I did have a pair in a dual setup on the '57. 3" mufflers down to 2.5" for the tailpipes. It wasn't too loud at idle, but it didn't take much throttle for them the cackle something fierce, so much so that it was difficult to get home from the track after midnight after Friday racing without disturbing the neighbors. I had to get them out of there for quieter mufflers.

 

if its quiet at idle then its an improvement, mine's loud all over. im sure it will be quietethen it is now but im wondering how good it will sound. nobody has a clip?

 

Who said anything about them being "quiet" at idle?

The clip thread doesn't appear to have anything with Bullets. Truth is, they're loud, don't have a mellow sound at all.

 

I have a sound clip of my car, stock manifolds, no cat, 3" bullet muffler in the I pipe. I'll try to upload it later.

Basically, it's loud.

 

Click the "Hear me!" link in my sig.

 

link doesn't work

 

fixed, sorry about that!

 

Urbanhunter: Sounds very loud and poppy, like ghetto IMO


Heres some more sound:
WAV of dual 3" Purple Hornies (Hedman LTs, 3" Xtenders)

 

Thats the problem though, sound recording quality, volume, position, acoustics, etc all vary the sound extremely. I think the recording is extremly raspy but it could just be a bad position. So many people toss a mic at the tailpipes, but don't forget that your ears aren't level with the pipes when you hear a car in person.

 

My friend was right behind the car with a camera, standing at normal height about 10 feet back.

It does sound raspy in the recording and does to some extent in real life. No cat remember.

It's extremely loud and racy sounding. I have never gotten anything but compliments in real life. It sounds WAYYYYY better than open headers/straight pipes.

And it does pop, that however is NOT due to the muffler/resonator design, however due to the fact the car runs slightly rich.

 

Im just wondering, so for all of you who run a single bullet, do you just have one tailpipe out the back instead of the 2 like it comes stock?

 

my setup is run specifically to have two tailpipes out the back:



The bullet is in the I-pipe before the rear axle, then splits into a Y at the top of the axle and out the back end.

 

Did anyone else replace the stock with a bullet and just one tailpipe?

 

I have a bullet and only a single tail pipe. The single tails flow better than any crossflow contraption you can make. Some love the cosmetic look of 2 tail pipes but if your all about function then a single tail is the only way to go! I had a flowmaster 80series on mine and swaaped it out for a single tail bullet and was blow away by how much better it sounded and got way better throttle response. diffinately picked up some power. Bullets have a great linear sound, they get meaner and meaner as you go up through the rpm band!

 

In regards to the sound, how much more volume does the bullet have over the flowmaster?

 

Take the flowmaster 80s series and triple the volume.

I'm honestly not impressed at all with Flowmasters. If you're coming from a flowmaster you'll see a gain throughout the RP M band and a nice change in tone, and it'll be MUCH louder. Flowmasters are actually quite quiet, imho.

The single tailpipe flows fine, mine flows good as well. Mine is cosmetic really, but when I put my hand to the pipes they are both flowing the same, so I'd imagine it's not impeding anything.

When I remove my cat-pipe and run with an open Y-pipe there is absolutely NO change in either ET or Trap Speed vs straight piped with bullet, so I'd imagine it flows well. And yes I have done back to back testing, with the same temperature /humidity and the same engine temps, very similar 60 ft.

 

I have Hedman shorties to a 2 1/2" Y pipe and the bullet sits where to CAT was and no tailpipe just a turn down...and if you dont like interior noise or very loud dont buy a bullet...get a Flowmaster...But i love it

 

i ran my camaro with no pipe from the cat back for a year and loved it, i worked at a dragstrip though so i was used to it and so were the people who heard it but it was a lil uncivilized for anyone else. i just got it back from the exhaust shop on thursday with a bullet and its SOOO quiet in comparison. Its growing on me though, it makes the car sound alot smoother and i can listen to my system at a reasonable volume now. it still scares **** burners though!
just took it to the track last night and i saw a slight improvement in et's, i managed to stay in the 15.7's all night, not a single 15.8 so my average et came down a bit but i didnt beat my best time of 15.65, came close at a 15.69 but no cudos.

 

so wait I have a question, I was thinking of getting Flowmaster 80 series for my car, but since some of you say the DYNOMAX is better should I just get that instead?

I have a 305 TBI, will the Bullet exhaust sound much better on my engine or will it not make much of a difference?

So what I am basically asking is if the flowmaster 80 or the dynomax bullet muffler would sound better on a car like mine.

91 Chevy Camaro RS

I want a car that'll sound mean at both idle and high RPMs, I listened to one person's flowmaster clip awhile ago and I must say it sounds good, but I like the DYNOMAX because it sounds awesome when it idles....

how much hp increase would I get from the two? Flowmaster or Dynomax?

 

You'd see about 5-7 more rwhp using a bullet setup.

The bullet might actually cost less as well, but remember they're going to have to do some fabrication unless you can find an entire catback system. Any good exhaust shop can do it.

IMO, a bullet will sound way better on your L03 than a flowmaster will, although being only a 305 it won't be as deep as a 350 with the bullet.

All depends on what you can stand. I have this system on my daily driver and love it. Some people hate that much noise and would rather have a flowmaster with a cutout. Your pick. IMO a bullet will sound fine.

 

I saw another post on TGO about mufflers and i think it was some guy that worked for Thunder Racing(i THINK), But he said the Flowmasters and the Spintechs are actually a very restrictive muffler compared to the Hooker Aero Chambered muffler. But a Bullet cant be too damn restrictive, because i can stick my arm completely through mine, but is 3" in and out. So a bullet would have to flow better than a Flowmaster. How much i dont know.

 

What do you mean by doing some fabrication?

I just wanted to buy the muffler, online at summit racing its like 38 dollars for the muffler only, what else do I need to install this thing?

I am gonna need new tailpipes I know that for sure, but what else?

 

I have dual bullets on my 305. They are mounted at the rear of the car.

Sound

 

There isn't a catback setup for this muffler. So if you wanted to run 3" pipes, the exhaust shop will have to custom bend them. Like I said before, any good shop should be able to do it. Shop around for prices. Mine was $150 for installation including pipes.

So basically, buy the muffler from summit. Take it to the exhaust guy and say "Hey!! (point to I-pipe) Put this thing in there and make me some new pipes!!"



If you went with the bullet you wouldn't be disappointed with the tone. And if noise itself is a concern, the bullet is actually very mello just barely pressing the gas so you can ease up your neighborhood at 2 AM

 

Eh I can see having a short exhuast could hurt low end torque a little bit but I don't see it effecting it that much

 

i didnt gain much back going to my new setup.
the exhaust has really grown on me since i last posted it sounds alott like a stock 4th gen trans am but much nicer at idle, subtract the percusion from decreasing rpms and you're almost there.

 

I just want to say that I hate Flowmasters, too comerciallized, tired of em' don't care if anyone gets mad.


The End.

 

I agree. Don't mean to offend the many, but they suck! Just look at the inside of them, that outta tell you all you need to know.

 

Thank You for joining on my side, flows need to be better.

 

the sound isnt bad tho for the flowmaster tho... its definately different

 

I agree. Different strokes for different folks. I myself do not like the raspy, crackle, pop note bullets give off. What I dont understand is if you can drop a pop can right through them, why put a bullet on at all? Just run straight pipes

 

My bullet doesn't crackle at all. It growls beatifully and puts the flowmaster 80 series I had on my car to shame in sound and performance. I guess it depends on the situation, I still have my cat on the car, maybe thats why it sounds nice and isn't over the top. Everybody from kids to guys working on their hot rods in the garage turn their heads to see whats coming when I'm going by. The car sounds great!

 

cause the bullets still actually muffle the sound a little bit better then nothing at all.
loud yeah but livable for daily dr iving

 

i had straight pipe on my car with the stock cat and its ridiculously loud at anything above idle. idle, its as loud as the flowmaster. but once you get some gas in it, it gets mighty loud.

and it had no tone to it. i didnt like the way it sounded. at 4000rpms it was gettin better, race car like, but down low, it was more like a annoying truck.

the dynomax will help tone it, and make a more enjoyable sound. some exhausts pop and crackle. my flow used to to that till i got the headers on. bullets usually have a raspy roar that i like and i havent heard many that crackle
