Post your sound clips here... I'm particularly wanting to hear the Dynomax catback on our little 6's

Idle from rear

Revving from driver side

Mind you these were recorded with my Compaq iPaq PDA but it's somethin.... I'm running a Cherry Bomb Vortex Turbo 2.5" cat-back exhaust w/ duel 3" chrome Monza tips.

Doward

Nice! Any of the Dynomax setup from anyone yet?

TomP

WWasem, never thought of that idea! I'll have to try recording some with my Dell Axim... I assume you did the "idle from rear" while you were standing between the tailpipes, behind the rear bumper? Where did you record the revving from? Did you keep the ipaq inside the car or did you reach it as far backwards as you could? (It'd be interesting to simulate your exact position if I record the Dynomax...)

Y2KFirehawk

Tom,
Yes, I was standing between the tailpipes behind the rear bumper, percisely! As for the revving, I stuck my foot in the car to reach the gas and reached back as far as I could. Yeah I agree it would be interesting to hear the same positions with different exhausts! :rockon:

I'm running Dynomax cat-back (no cat) right now. I'll toss up a sound clip as soon as I get a chance for you...

OPen manifolds on 3.4

really cheesy recording , used mini headphones for mic , but you get the idea. Sat in drivers seat & let phones just dangle under car.

Doward

YES! Thank you!!

BackInBlackGP

I will try and get a recording device in my garage on Wednesday. The exhaust is a bit raspy at high, no load RPMs, but has a nice low mellow tone at idle.

Doward

yeah... I wanna hear it running!

TekViper

heres two sound clips of my 3.1L with a performance muffler and high flow cat. they didnt come out too great and it is backfiring a little less now these days. it sounds 100x better when the car is under load, the v6 just isnt a good sounding free revving engine. it sounds sweet at idle and under load accelerating though.

TekViper - Mine used to sound kinda like that and backfire some, but after I replaced my intake with a CAI, it eliminated the backfiring. It sounds nice and smooth now...

TekViper

yep i took my intake arm off temporarly and the exhaust sounded a ton smoother. i havent gotten around to fixing that stock intake yet though.

92RS3.1L

How much of a performance increase did u get with the SLP cold air intake?

Well, here you go... If you have a subwoofer, I suggest turning it up for the full effect!

Microphone was 6' behind car, 1' off the ground.

i'll see if i can get some sound clips of mine on here soon. i want to get some with open headers too!!

AGood2.8

I don't know if its just the recordings but my car doesn't sound like any of them. I.m hearing hesitation and popping in just about all of them. My motor sounds very smooth and throatly compared to everything I've heard here. I run a flowmaster/ Gibson setup, w/ absolutely no crackling or backfire noise what so ever Not one of you even come close to sounding like a V8 at ilde of revved.

AGood2.8

After listening to these- mine sounds closest to this, However this sound clip still sounds tinny when it revs- mine sound smooth (not popping after throttle lift) and quick revving like this but more throaty: http://www.exhaustsoundclips.com/sou...rochamber.html I'm not getting the vippy revving sound that this clip has, this still sounds like a Honda

V6camaroman

those are all good clips guys. mine right now sounds very similar to TEKVIPER just mine is a hair louder. i do like the dynomax clip of BACKINBLACKGP's. is that the whole dynomax system?... int pipe, muffler and tail pipes? is sounds good. the only part i dont like of the dynomax's is the idle sound the rest is great

Y2KFirehawk

I feel a lot more power especially at highway speeds. And when it is hot outside and such, I don't feel as much of a power loss due to the heat. Definately improved the tone of the exhaust note. And I like that it looks stock.

I don't feel as if I have any hesitation or popping/backfire. I believe mine sounds very much like a V8 at idle and revved. I think I will record it with a DV camera and see what I can get out of that then. The quality wasn't the best because I recorded it with my PDA...

IndyTruck

AGood-- That Aerochamber clip you linked sounds awesome. But what parts are in your Gibson/Flowmaster setup? Can't wait to hear that!

kevin

BackInBlackGP

Yes. Yes. And yes. The recording doesn't do it justice. It needs to be heard in person to truly appreciate the fact that it's only a 2.8...

The idle in the recording is a little bassy. I've used a sound pressure meter at 10ft, ground level before... IIRC, I peaked out around 110db...

AGood2.8

Just a Gibson high flow cat 3" in and out but tapered into 2 1/2" pipes for and aft. The muffler is a standard Flowmaster 80 with 2 1/2" in and ( I think here might be the difference) with only 2" dual coming out and NO tips. It sounds deep but not echoing resonating through the smaller duals- gives a very smooth sound. My motor mods and intake also play a part in its sound- I don't have any restiction in intake flow what so ever and the roller rockers, power pulley, and smaller diameter convertor give it a quicker rev combined with the hottest ignition setup availible for smoothness.

AGood2.8

Yours sound just like a 12A rotary mazda motor- and I did here a pop in the decreasing r's, not percise time each rev but there after each, the first rev is clearly heard, the second set of revs the pop comes delayed.

Edit: keep in mind what you are hearing on your computer and what I am hearing on mine may differ based on the quality if your computers sound system. I have a very high quality sound system on my computer and your clip doesn't sound remotely close to a V8, sorry just being honest. I don't think mine sounds like a V8 either.

AGood2.8

Here's a sound clip of mine via a tape recorder transfered to computer- hope this works.
Edit guess not, I have to figure out how to upload the sound file.

Doward

email it to me, I'll see if I can host it - Doward_@hotmail.com

92birdie

I dont want to spend a grand and I dont know how to do anything witht he exhust.
Which sounds the best for the money flows?cherry bomb?dino?
thanks

I hate freeservers... *sigh*

Doward

Can anyone here host a 250k MP3 file? My current Freeservers setup won't allow remote posting. : /

Project: 85 2.8 bird

get a Raven exhaust, sound great w/a 3.4 when I heard it.

AGood2.8

Doward, I tried to setup a cardomain page and "host" it there but that doesn't seem to want to let me either?

TomP

My turn!! My turn!!

Finally got some recordings! Turned my pocket pc (Windows version of a Palm Pilot) last wednesday and found out both my batteries ran down, lost everything. Got it going this weekend, and here I am with some sound clips!

I tried to copy WWasem's placement of his pocket pc. For the idle noise, I held the Axim about a foot behind the bumper, at waist height. For the revving, as I worked the gas pedal with my foot, I had the door open, and reached back as far as I could.

There's a lot of static on them, sorry 'bout that. I don't get static if I do a normal voice recording; maybe the little built-in mic couldn't handle a car's deep exhaust? Or maybe my MSD box was interefering? But my MSD doesn't come over my car radio... oh well.

Website is here: http://www.geocities.com/tomp_3rdgen/exhaustclips.html

I'd say to turn up your subwoofer, but the static bursts might pop your regular speakers out! Let me know what you think... oh and I can't remote host from Geocities either, that's why I made that quick-n-dirty webpage. Those javascript errors aren't mine!! That's what geocities adds to the end of every page.

Y2KFirehawk

Sounds good Tom! As for the cracking during the recording, I'm not sure if the Axim's come with Pocket PC. But if so, if you didn't already, you can click on Start, then go to Settings, and then under the System tab, I have an icon called Microphone AGC. And what that does is automatic gain control. That might help things out.

Also you can go to Start, Settings, open Input and then click on the Options tab and you can adjust the voice recording format. I have mine set on 11,025 Hz, 16bit, Stereo (43 KB/sec).

I'm going to try and play around with your recordings on my computer to see if I can eliminate the pop sounds and static in the background and see if I have any luck with that.

TomP

Hey, thanks! (Axims come with Pocket PC 2002) My mike gain was all the way up, and my voice recording was set to 8,000 Hz, 16 bit, Mono (16KB/s). I guess that's good for voice notes, and nothing else. I changed the recording to your setting, what did you have your mic gain set to? I'll try another recording when I go home. Might seem odd if I'm revving my engine at work

Y2KFirehawk

In my microphone gain control I just have two options, Enable and Disable... LOL! I think changing the recording settings should put you on track though. I played with the recordings of the other one on my computer and the program I'm using isn't that spectacular and in order for me to get rid of the "pops" I would also be changing the tone of your exhaust... At one point I had your car sounding like a 454 BBC!!

TomP

I've got 6 settings on mine; a slide-bar from low to high. Currently it's set to "high". I'll try it in the middle.

I thought my exhaust would sound like everyone else's, but the recording is pretty accurate (other then the static). Strange. I figured the recordings were distorting somehow. How did you other guys measure yours? Like AGood said, there's really no hollowness or backfiring coming from my exhaust... maybe it's the y-pipe I have?

Hey, wait, does your Compaq have two microphones? I'm pretty sure my Axim just has one; I'll try a recording in "mono", too.

after hearing all these i would have to say mine sounds the best. no joke.. i have them on pc but dont no how to get them on the net some one tell me and u guys could hear for your self.

Y2KFirehawk

But the sad thing about Geocities is.......

Y2KFirehawk

Another note about you guys uploading your sounds and such....

Most ISPs, the ones around here at least, give you FTP space. My cable modem ISP gave me 10MB of space on their FTP. I know AOL gives you 10MB of space as well I believe. Or is it you start with 5 and then over time they give you 10..... I forget..... But you should check and see if you have your own personal FTP spaces. If you do you can upload the files there and link them however you like.

I know for AOL users in order to get to your FTP space, it is keywork My Space. And if you discover that your ISP does in fact provide you with FTP space, the website below is a simple guide as to how to connect to it.

O.k. screw it- My car goes Vroooom, vroooom.

Hows that! I hate computers

TomP

Yipe.. did that happen to my site? No... hm.. either nobody listened to my sounds or my file's much smaller then AGood's?

I was going to re-record the exhaust, came home from work and passed out; woke up a half hour ago... I can't wake the neighbors up this late. Maybe I'll go find an abandoned parking lot tomorrow during lunch.

AGood2.8

I think the problem I'm having is my file is a "WAV." file and not "html". Will a wav. file work with your method?

AGood2.8

I just decided to take a little time and email all that posted (those with email links in their profiles). Figured that is easier than messing with this hosting crap anymore. I you didn't get it and want to hear it- just email me at AFrikinGoodTime@aol.com.

You guys will notice that my motor revs quicker the any of yours- what that is from is my buddy Jimmy who owns Darrell Young Racing Transmissions built me a custom 700r4 for this little V6 motor but used a special spleened HD input shaft and had the convertor shop build a custom smaller diameter convertor for this application- thus resulting in less rotation mass and more power to the pavement. The r's also wind up quicker from the y-pipe (instead of t-pipe), roller rockers and power pulley.

TekViper

hard to tell from the clip, doesnt sound like u revved it too high, maybe 2-3k? in my clip i was at or a little past 5k. it doesnt backfire as much when its fully warmed and never under load. one of these days ill record a better clip of my car, the ones i have posted now are from my webcam hanging out the window and the car in the driveway.

AGood2.8

Each rev went to about 4500-5000 rpms, This motor revs way quicker than a stock 2.8. Thats the whole point of me trying to post its clip. Mine sounds much different than any other in tone and rev speed. Just to show what can be accomplished so far with a little wimpy V6
