Are people exaggerating when they say that these engines sound horrible at anything above idle? Or is it true... Does anyone have any sound clips? No idling clips please, i know they sound good at idle.. Im more looking for outside shots, im sure all you can hear from the inside is the supercharger whine :P

In my humble opinion, it's no exaggeration.

It's a great motor, makes lots of power, inexpensive, responds well to mods, and looks like it belongs in the Fiero engine bay...but sound good under throttle...not so much.

I have yet to hear one that sounds good at anything other than idle. Heck even a duke sounds decent at idle, but once you wind up the 3800 it sounds like a V8 that's missing 2 cylinders...because that what it is.

something like a baby with pots and pans well maybe not have you ever heard a non z28 or a firebird with exhaust 98-02 model just really raspy not the normal deep tones of a v8 or such

if you dont like the way it sounds, just throw a nice muffler on it, quiet it up a lot and you'll have yourself a sleeper...

You tell me bro, what's it sound like to you?

Has anyone ever done a true duo exhaust with headers & no crossover pipe? That should make a considerable difference in sound.

i think you should just put on a recording of a V8 in your cd player and it would sound much better .

flow masters on the 98 bird n/a sound like **** at high rpms it idle it sounds badass and mid way dosent sond to bad high rpms it just sounds to raspy.

Let me guess...you are under 21 years old? To those of us old enough to remember a muscle car, supercharger whine is not what I want to hear when I punch it. Not that there is anything wrong with that, just not my cup of tea.

to tell you the truth i think the best sound to ever come from a car besides for exotics is the infinity G35 fx35 muerano (if thats how you spell it) and the chrysler 300m special

I dont know about you guys, but I'd rock it. It aint no northstar, but its one hell of an engine.

3800's bug me because alot of GP guys kind of ruin it for me with their N/A cars. However that car in particular is pretty savage.

i agree but you can still pick up that raspy noise even out of that had i known it was going to make my firebird worse i would have never put the flowmaster on it but the good thing is at low rpm's it sounds good and for some reason my firebird is starting to sound better

At idle and rolling into it my car sounds good with a nice rumble--Anything after that then it sounds pretty nasty but I have no complaints.

anyone have any drive by shots? Going by the 2 videos posted, its not that bad.. Theres a local guy that has one, so ill hear it in person at some point, but i want to hear more from your guys experiences..

Is there some sort of law forbidding anyone from driving an old school muscle car until they're 21?! What does age have to do with understanding/appreciating the dynamics of cars of the 20's, 30's, 40's, 50's, 60's 70's, 80's? Why would anyone need to be as old as you to know what you're talking about? Don't be so quick to assume.



And just because its all you had growing up, doesn't mean that its something I'd necessarily want.

I dont know about anything over idle. Ive had more than one car guy ask me if it was a V8 after I drove up, and complement on the sound. Im not to sure about at WOT, as Ive never heard it at WOT from the outside, and im a little more occupied trying to keep in a straight line when Im nailing it.

the 3800's problem with sound is it's fire order. The 60 degree v6's (like the 2.8, 3.1, etc) have a 180 degree fire order (bank-to-bank), 1-2-3-4-5-6

The 3.8 is more like a small-block 1-6-5-4-3-2, (still bank to bank...huh, i thought it was different than that) plus the degrees of separation are more like the v8, making them a little bit uneven, especially compared to the purpose built 60 degree 6ers.

I've heard one, maybe two nice sounding exhaust systems for the 3800 (for the entire RPM range. Most sound decent at mid-low RPM, but get over 3500/4000 and they sound like ass). Both were in a Camaro, and both were fairly expensive and custom work. My favorite used headers, an H-pipe and 2 borla mufflers that dumped out over the back axle. It sounded pissed

I loved my 3800 Camaro, but I like my Quad4 Cavalier better (Yeah, I got another one...muahaha!)

EDIT: Of course, I love my Fiero best of all!

They might sound awful but I won't complain about 360HP+ with less weight than a V8!

yes, the 60dV6 sounds so much better

really does. something I really noticed at the 25th track days.

I'd expect with some header & exhaust options a better sound could be created - but - I do beleive the output/performance is what counts.

I guess I am biased... When I am driving it, I am not aware of how the engine actually sounds, as I am too busy grinning. I do know that the sound at idle is okay in my book. But I must not be an engine sound connoisseur.

So if the majority says it sounds like @ss, I guess it must... but it is still a joy to own and drive.


BTW, mine has a flowmaster 80 and I replaced the stock "trumpet" resonators with oval resonator tips.

What car/dash is this? I really like that instrument cluster. Is it an all-LCD panel? Just 3 days ago I was drawing up plans for an LCD cluster. Please tell me what car this is (I read the thread, but I didn't see it) Thanks.

I'd rather be driving the L67 than my DOHC, and that's one of the sexiest exhaust notes on the planet! Jncomutt has no issue passing his beast exhaust note off as a stroked 383. I prefer a quieter engine with more charger whine.

The video I posted is of an older Holden Monaro with an intercooled series V blower. It's equipped with analog gauges, they're just hard to see in the video.



Speaking of which- Jncomutt's new Turbo setup. Someone outside mistook the sound for the Mustang Cobra that was parked in the next bay.

I'd rather hear the supercharger wine, than a loud exhaust any day of the week. Kinda like the Supra I own. I want the quietest exhaust on it that I can find, and let the turbo make all the noise as I accelerate.

I'm the type that likes to make people guess as to what's under the hood, and find out only when I leave them looking at my taillights.

Mine sounds good at idle, but i've never heard it at high speed, guess the sound never catches up !

You must be younger than 21 Deabioni.

Pardon my ignorance, but can someone explain why you cant change the firing order?? Im sure it would be costly, custom parts, but idk.. maybe i dont understand it all :P That would be the crank that determines the order right? Couldn't you get one custom made ($$)?

[This message has been edited by kawana (edited 11-12-2008).]

You're on the right track. It all has to do with physics, you can change the firing order (crankshaft, electronics, camshaft), but the hardest part is keeping everything balanced. 90* motors have an odd splay angle, so it makes balancing each throw very hard. You end up with three configurations today for the 6 cylinder:

Straight Six Firing order: 1-5-3-6-2-4
3800 90* splays: 1-6-5-4-3-2
V6's with 60* splays: 1-2-3-4-5-6

You can't really change the firing order on the 3800, and still balance the block without adding balancers etc. Besides being almost impossible, it'd cost more than twice what the car's worth. Be happy with the 3800 for what it is. If you want something exotic, go with the 60* V6 or something foreign. The reason 60* V6's are so smooth and fire, 1-2-3-4-5-6 is because of their 60 degree throws. So: 1 throw each 60* = 6 throws in 360* (a full rotation) / 12 times in 720* (a full cycle). The engine almost balances itself entirely without a balance shaft.

They sound horrid.

Put a turbo on, and a decent turbo style muffler, and it changes into more of a roar than a sound. Any other time cruising around, you just hear the turbo spooling. 3800's sound decent at idle.

Its near impossible to make a swap exhaust quiet, short of putting 2 full size stock mufflers on it, and modding them so they can flow a decent amount.

Is it really something you notice from inside the car? Or is it pretty much drowned out? Say your going like 70mph, but your not going WOT, will you hear the supercharger, or will it not really be screaming?

Oh, and while were on the topic of exhaust systems, what would it sound like if you each cyl. bank had its own exhaust system, like instead of both sides joining up. Im not thinking of doing this, im just curious what it would do to the sound... probably sound like ass :P

Pardon my crude paint skills Obviously you'd have to squeeze a muffler in there, but you get the gyst of what im saying..

Actually, I thought about that too. Having to seperate outlets would be interesting to see if you'd gain performance. I'd think maybe abit more, but someone would have to try this to confirm if the HP gains are there. Let us know...

I am using nothing but a single glass pack and I love the way it sounds.

do you have any clips of it? And by "love the way it sounds', do you mean at idle, or WOT?

Coming straight out of a spintech muffler at the time. Sounds a little more civilized with the tips on it now. More directional less reverberations into the cab.

Ah, i just finished watching that video too. Think you could shoot another with more WOT hits/less talking lol :P I guess its hard to really tell if i dont see one in person :P

I'm not claiming it sounds like a V8, but I love to hear it!

Yeah I'm gonna try to get out tommorow. Been meaning to get some new video since I got the exhaust finished.

My 3800SC series III is loud and that's with a 3" in / dual 2 1/2" out Flowtech muffler AND two pair of Heddman Hot Tips resonator ends. . At idle it rumbles and at road load it quiets down to a rumble but at WOT all hell breaks loose. Like em loud then you'll like the sound of the 3800SC and as Darkhorizon has said its almost impossible to have a quiet exhaust on this engine with a modifed free flow swap exhaust. If you want it quiet only one system will provide it- a set of WCF headers with a CAT a muffler in the stock location, stock exhaust routing and with dual exhaust tips.. A guy in my club runs this system and its not very loud. Only one problem; this setup will zap some horsepower
