View Full Version : looking for a really loud exhaust
hey guys im new here and new to the silverado scene, ive had an s10 my whole driving life, so stepping up to the v8 is a big difference... what im looking for is pretty the loudest exhaust set up i can get without losing MPG, maybe even increasing it a bit? added power doesnt mean to much to me, i dont really care, i just want MPG and loud loud sound at all rpms ya know?
cliffnotes: Want to keep MPG the same or perhaps increase, with the loudest exhaust i can buy
thanks guys, and btw its the 4.8 v8
thanks for any help :)

MagnaFlow rocks.
FlowMaster sucks.
Zoom,

LT Headers, off-road Y-pipe, Dumped Dynomax Bullets. :D
thats my plan
see everyone is trying to sell me a flowmaster 40 or a flowmaster 40 "super" catback system saying it will be the loudest... that true?
oh and are the dynomax bullets a strictly race muffler? meaning it may throw off stuff like the computer or somethin?

Flowmaster 40 rocks
Magnaflow sucks
seriously though, I've got a flow 40 dumped not 6 inches past the muffler. LAF. but still nowhere near as loud as my straight pipe 2.2L S-10 was.

A 40 will be loud at all rpm's, but at wot a bullet will be much louder. Also, the 40 is actually said to make you loose some power. But you don't care about that..

I jsut posted this in another thread, But this is my set up with stock manifold, no cats, and 14" bullet dumped at the axle. Definatly load as fuck. It was actually too loud because it was really raspy at certain RPMS.

ok i got a magnaflow single inlet dual outlet exhaust with tips and it was kinda loud but i wasn't satisfied so gutted my cat and now im seriously one of the loudest (without cutouts) i have seen in my town.(still got stock manifolds and y-pipe) im setting off alarms at a fast idle. mine doesn't really smell though. the sound is probably the only good thing about my truck.
you wouldnt happen to have a sound clip would you 95sierra2wd2dr?would guttin teh cat interfere with emissions at all?
and VicRed, your vid doesnt want to play for me right so ill try tomorrow
thanks 1989K1500, ill look more into that site
and thanks to everyone else about the 40 series mufflers and magnaflow!

I have the 40 series flowmaster. It has a nice tone to it, but I wish it was a lot louder. I've heard a few trucks with Magnaflows, and they are quieter than mine.
I would try the Dynomax Bullet.
is the dynomax bullet sorta like taking the cheap way out??? is it like doing a glasspack? or w/e they are called... i dont want some cheap set up thats gonna harm my gas mileage or amount of power ya know? cuz they say on it strictly race muffler
just run 1? at what size? or run duals? that might be a bit too intense

Yes, being in CA, you will be screwed if you don't have a functional cat.
FlowMasters have a good shot of taking a bit of power away, but they are loud. MagnaFlows are mellow when you cruise, and loud when you put your foot in it - and they are more likely to give you a little bit of power.* I honestly don't know anything about DynoMax, but they have a good rep, to my knowledge. True duals on a 4.8L is going to be an overkill.
Also, I think if you dump it, right after most any aftermarket, 'performance' muffler, it will be a bit louder - though it may annoy you with some resonance in the cab.

*And, generally speaking, if you have more power, without adding more fuel, you are using less fuel to get to the same speed, which means better MPG. Generally.

No, a bullet is not the "cheap" way out. They have a great reputation. I have 2.5 inch true duals with x pipe and 2 12' bullets dumped on my 5.3. It is a little overkill, but I have more modifications in my future to put it to better use. I noticed a little better gas mileage also.

I went Magnaflow, no complaints since. But if you want loud mine were not nearly as loud as I expected. But I didn't want loud as much as I just wanted performance. The Magnaflow muffler is straight through so I was suprised when it wasn't super loud, but when I get on it it gets nice and loud so it's there where I want it. Cruising isn't that bad. I'm sure LT headers and an offroad y would make it loud as hell though ;D

No mufflers at all. Mufflers are for old people and girls.

that just makes me even more anxious to get my truck back from the exhaust shop so I can get to hear it with my dual 12" bullets :evil:
alright thanks for all this help on this guys.... i wanna go ahead and go with the dynomax bullet then....
a few questions about them now;
with this being a straight racing muffler, will it throw something off?
what size should i go with? i hear people with different size bullets 9" 12" 14" or somethin, what would the outcome difference be?
can i still pass emissions?

yes..........BUT you won't be able to pass any CHP with in a 1000 yrds. with out getting pulled over :bawl:
i deal with them all the time at work and there starting to crack down on loud exaust, jacked up trucks, street racing, tinted windows and a lot of outher BS. but under CA. motor veh. code they can. IE. we inpounded a chevy pu. a few weeks ago with a 12" lift, and 36" tires, got him for NO CLEARENCE LIGHTS on the cab, and NO SPLASH GUARDS becouse the tires petruded out side of the fender wells
the owner was a dick and got what was comming to him

OK, well let me tell you first that I'm currently running dual 40's series mufflers, each stacked side by side in the stock muffler location, 3" in/3" out to 3.5" tips. I love this setup! It is extremely loud at all RPM's and doesnt crackle at all. I'm easily the loudest in my area. Problem that i'm having is this. Your looking for better gas mileage, but if your looking for the loudest truck at all times, from experience your foot will be in the gas alllllll the time. I probably lose 3 MPG because I want that excessive noise but cant keep my foot out of it, As i like the load noise all the time too. Only other option to better it a little would be invest in a intake but not by much. Just my experience.
Chris
thanks for that link boomer, it sounds really good
and, 2002HeavyChevy, i know what your sayin about keepin your foot in it, im like that with my little truck cuz i love the sound. im not really looking for an increase in gas, i just dont want the set up to make me LOSE mileage, not my driving, just the set up itsself. you wouldnt happen to have a sound clip would ya?
thanks

11-09-2005, 06:57 PM

I dont know what the loudest exhaust would be but I know true duels with out mufflers are pretty damn loud. I know a couples people with that set up and its retarded how loud it is..all the time. forget about volume man you should be thinking about tone. what sounds the best not whats the loudest.

11-16-2005, 10:21 PM
^^^He does make a point a quieter exhaust with a good aggressive tone will sound better than a loud ass exhaust with no tone anyday. I have a single Flowmaster 40 muffler and it is loud and has a good tone to it. I just wish i could take the cats off and pass emissions.
silveradoreb
11-16-2005, 10:40 PM
I have had bullets, a super 40 and reg 40 and no muffler on my 5.3. Then I took off the cats, which made everything extremly loud and popped like a sun of a bitch. The best sounding overall is just no muffler on a 5.3. Right now I have two tiny ass hi flow cats off ebay, they were 36 bucks each and no muffler. This is the loudest and best sounding yet, it pops real bad when it sits, or is cold, but after you get on it for a couple min it goes away and sounds great.

11-16-2005, 10:59 PM
The smaller the muffler the louder. In order to get loud, run larger pipes, headers wouldnt hurt, small ass mufflers dumped with no cats.
angelofdeath
11-16-2005, 11:36 PM
just get a bullet muffler and down pipe that bitch from the muffler! no exhaust pipes or tips. slap on some LT pacesetter heads with a y pipe. thats what i did. and it sounds like no other. louder than the 40 series, coz that what i used to have.
StrokerAce03
11-17-2005, 12:19 AM
I had true duals on my 4.8 with straight pipes after the cats and 4" tips. It was loud but it sounded damn good. For the best tone IMO go with either a Dynomax bullet or Hooker Aerochamber. Hooker makes a Max Flow too that's louder than the Aerochamber but I don't know how good it sounds.
man no one really talks about the hooker line....
would you consider the hooker aero/max flow better then the bullets?

No muffs are the only way to go. My 5.7 pops bad when its cold but after a few minutes the poping goes down alot and it just sounds so badass.

You sent me a pm about my spintech exhaust, but I thought I would reply to this also.
My spintech on my 5.3 is loud, I'm going to try and get a sound clip for you tonight, I just got internet hooked up at home yesterday, so I will be able to do it there.
Dynomax is good stuff also, I have dual 2.5 inch Race Magnum welded on my 81 pickup, I don't know if they make those mufflers anymore, but I love them. Aggressive idle and cruising but when you get on it everyone knows.
I'll try to get that sound clip tonight, if not I will get it saturday morning for sure.

kool man, thanks for the help.. im gonna check and see about those race magnums
what my dad thinks is that since the bullet is straight through, ill lose backpressure, and he thinks more then likely it will throw a light or somethin....

11-18-2005, 07:14 AM
Well, you probably won't throw a light for too little backpressure, but you are definitely going to lose low end power, what some of the others said about 3 inch being overkill on a 4.8 is true, unless you are going with a single. I ran into this when picking and exhaust for my 81, after talking to many people about it, I came to the conclusion that large diameter exhaust on a smaller v8 is for racing, something that will be held at high rpm's for extended times, that's when the benefits show. But for street driving, the loss of low end power isn't worth the gains in high end power. Some backpressure is needed for torque, otherwise your motor just spins up faster. :imo
And I will have that soundclip for you tomorrow morning, I'll try to get to an area where I can do a drive by. (my wife is going to think I am absolutely nuts for this :LOL: )

OP,
Take said vehicle to Burns Stainless, open wallet, hand them lots of cash and/or credit card, and then profit and an extremely loud, well built exhaust, that will do everything you want.

I'll tell you what's the loudest exhaust, on my best friend's 5.3 he had cut off the stock exhaust right at the flange after the y-pipe and welded on a piece of 3in pipe to the back of the cab. It was retarded loud at all rpms, didn't pop or crack, but you could hear the annoying sound when the rpms drop after a shift. It set off alarms all the time, but he never got a ticket for it. And the drone was only slightly worse than a flowmaster on the freeway. However, what did happen is after a year of towing like that, it burned up one of his kittys from not having sufficient backpressure on the exhaust. So after changing the y pipe with new cats he went and had a magnaflow 18in put on with tips out the back and everything is much better now.
Okay story time is over, just wanted to keep anybody from burning out a kitty if they didn't want or mean too, ya know.
jschrock
06-29-2011, 11:46 AM
Are you serious? Please tell me you are joking.....are you Elkins brother?
BACK PRESSURE is BAD.....do not know how else to say this.....the only way you could fuck up something by reducing the back pressure is to run too lean because the reduction in back pressure allows more air into the chamber and in turn burning a valve or causing a pre-ignition knock on a CARBURATED engine, newer engines/efi can adjust for this. It will not fuck up a cat.
