Just wondering. I know some people emailed the guy and received answers but the whole subject disappeared or maybe....people just aren't talking
This is supposed to be a stock 2.8 with custom made headers and exhaust:

It isn't a GM motor... I read somewhere that it had been swapped out with a flat crank 6.

180* headers. There are pics floating around of his set up

Wow, sexy. it sounds like the kin of a ferrari.
it looks like a stock 2.8. its all in whatever the Cat. Convertor (if any) and Muffler are.
it sounds like what a 2.8 should be at idle, exept it smooths out the "choppy"-ness at higher rpm.

I want to look into this for a friend, he wants his Lizardo kit to sound like this...

Thats what i want my IMSA to sound like

I've seen pics of this guy's setup and it appears that he has the middle cylinder of the motor separated from the rest of the header and joined somewhere else. I don't know if that makes the sound different since the exhaust would then be "out of sync" with the stock sound making a more smooth sound.

It is not a stock fiero 2.8 motor. It is a 2.8 out of some car in Taiwan. There was a new member from Taiwan a little while back that knew the guy whos car was in the video. He listed what kind of car the motor was from in his thread, but I dont recall what the name was? I'll see if I can find the thread. --Greg

Edit to say the car the motor is from is a Vauxhall VXR

No, it's not the 2.8 DOHC. It is the Fiero 2.8. You can see the stock intake in the video, and there is enough evidence between the video and pictures on the blog, to show that it is a Fiero 2.8. However, the exhaust is very complicated. It is not 180 degree headers. But the exhaust is quite wild.

The one video I saw, not this one. Didnt show the motor. Maybe this one is the fiero motor, I didnt really look. But thats what I was told about the other one I saw from a guy from Taiwan.

Did you guys not see the stock Fiero intake in the engine bay with the exhaust note clearly attached to the throttle input?
Edit: beaten to it.

Flat crank V6? 180* headers? Seriously? This isn't a V8...

It's not too far out of the ordinary, my GM 60 degree V6 Camaro sounds very, very similar with the Corsa catback. It has regular 'shorty style' manifolds and is a dual exhaust the whole way back with an X-pipe in the middle. That's why I bought the catback... while it is an unusual sound coming from a Camaro, I love it just the same. Corsa tunes their exhausts per application to get exactly the sound they desire (that's why they don't sell mufflers alone).

I looked at pinniferrina's threads and he said that he was friends with the guy and the exhaust was VERY expensive. That was the extent of the discussion in the thread.

quote Originally posted by 87antuzzi: 180* headers. There are pics floating around of his set up

I don't know how many times it has to be repeated... 180* headers on the 2.8 aren't possible because the firing strokes are at 120* to each other. Also, if the pics of his set up were clear, then nobody would be talking about this anymore, they'd be doing it. The fact is nobody has figured it out, and if they have, they're not talking. Personally I'm rather skeptical of the whole sound clip on the video... with the amount of effort that people on this forum have studied it, you'd think someone would have the answer by now if it was legit. It's kind of like the Loch Ness Monster... shrouded in mystery to keep the interest alive.

Well I am sorry I did not watch the video to see the intake manifold the first time, MY FAULT! I remeber someone telling me about putting the Vauxhall motor in these cars, because fiero parts aren't as accessible in Taiwan. This is why I usually dont post very much, because you make one little mistake and people like to jump on you..

Post away. I remember the Vauxhall motor scenario in another thread also. I just wonder why it is so hard to get an accurate answer from this guy with details of his exhaust.

Here's a good ol' GM even-fire 60* V6... (skip to 1:44 for revs) This isn't my car but I have the same thing.
It's pretty close to that Fiero's sound, just less 'bassy' probably because it isn't in a parking garage like the Fiero is (my Camaro sounds like that in the parking garage, too)
As previously mentioned, it's a normal dual exhaust with an X-pipe, just tuned for that sound.



(edit) BTW IMSA GT, I saw that you posted in this thread, doesn't that cover it pretty well or am I misunderstanding?

It looks like it would not be too hard to replicate after reading his Blog in the above link and seeing the pics.


1 to 3 and then they combined feed into 2 and the same for the other side. Looks to be true duals as well with simple glass pack style resonators.

Relax. You made a mistake and it was corrected. Sometimes, many people might correct it in quick succession. It's the internet, and everyone can't see what everyone else is typing all at the same time. Accept the fact that you were wrong, and be done with it.

well sorry .

I actually was in contact with one of the Taiwan guys. The engine is a stock 2.8 and the exhaust system was custom made there. I have a number of pictures that he took and sent to me. The car has been sitting for awhile and is currenly in disrepair. The pictures I got are relatively dark and hard to make out. They used what appears to be a small diesel truck resonator instead of a muffler and mounted it where the cat normally goes.

One of the guys here has duplicated the system, and I hope to hear how his sounds when the build is complete. While it is not a 180 degree system, by crossing specific exhaust ports from one side and mating them to the opposite side, along with the diesel resonator, they managed to make an exotic sounding system.

If it can be duplicated, I want one for my 3.4 PR.

Looking at his set up and what he posted in his blog it doesn't look like he crossed side to side at all...

quote Originally posted by deezil: Looking at his set up and what he posted in his blog it doesn't look like he crossed side to side at all...

At least one cylinder on each side has to be mated with at least one cylinder on the other side, given there are an uneven number of cylinders on each side.

After some still frame shots of his video His blog doesn't really match what the exhaust is really doing.

Too bad my turbo will kill any chances of that type of sound, but I guess I can live with the ear-shattering wail of Earth being forcefully inhaled instead.

Just for stuffs and grins, I'm thinking about pulling off my Camaro's Corsa mufflers and sticking them on the unterminated pipes currently coming to the rear of my Fiero, once it's running and back in my hands. The mufflers are a 2.5" slip fit and the Fiero tailpipes are 2.5". Perfect for a sound test. If it sounds at all good I'll be sure to post it up.

BTW, this thread made me want to go for a relaxed drive in the Camaro, so I took it around my 'loop' and hit 7k every chance I got. Coming under that bridge entering onto I-95 with the windows down while screaming full-tilt at 7000rpm sounds SUWEEET.
I don't care what anyone thinks, the LLT (3.6 DOHC VVT DI) is the PERFECT engine for a N/A Fiero. There are a few others that are more powerful and faster, but nothing would deliver that pure intoxication like this one! It is the 3.4 DOHC for the new millennium but there's no real comparison as this is a properly designed high compression 7000rpm all-aluminum DOHC V6 with ample power from 2000rpm all the way up, topping at ~325hp as installed in a Fiero. Times are good.

Not really.

quote You can find the cylinder 1 and 5 merge together first then re connect to cylinder 3.

Cylinders are numbered on the 60* V6's as follows:

135
246

So 1, 3 and 5 are on the same side.

you will get a very similar sound with a set of nice equal length headers and a tubi muffler. my .02

I have the same sound with my 3.4 and here is why. My 3.4 has short headers, the Y pipe joins to a single cat. The after cat pipe goes to a single inlet borla muffler with dual outlets. The outlets run to the back which take 90º bends to head back to the center of the car for a center exit exhaust. The exhaust tip is like a large plenum that accepts both exhaust pipes. The combination of headers, bends, borla and center exhaust sounds just like the video.

All this stuff was covered in this thread. And the link describing how the header pipes are merged has been posted above.

Needless to say, this subject has come up often. And it seems everyone's questions have been answered many times. So please excuse me for being terse.

Can you make a vid?

This is outside in the wide open. Had I done this in a parking garage, your jaw would drop, the sound is sweet as hell. I went though some sustained rpms to let you hear the tone. none were actually wide open.

Ok exhaust Gods, please make this kit. Make it for the 3800,3.4 dohc and the 2.8 and 3.4. This will be so nice.

Just goes to show you that exhaust tuning can really change the sound. While its good to be creative and have a nice sounding exhaust; a slick sounding exhaust isn't going to help you win any races.. I have only one concern-HORSEPOWER and getting from point A to point B as quick as possible. If my exhaust sounds like sh*t so be it but I actually like my 3800SC exhaust sound. .

That was the next question....what impact would this type of exhaust routing and splitting have on performance. Meaning, you won't gain any horsepower from this but will it actually kill what little stock power the motor has?

Thanks for the vid but I Do not think it sounds much at all like the Taiwan fiero exhaust.

Sell them Fieros and get yourself a helicopter. Cars only move as fast as the traffic around them (and any police around to enforce the laws you already agreed not to break).

Actually it can help if set up right.

it creates a scavenge effect and does create horsepower. it is minimal, 8-10hp, but it is horsepower. if hp is your game there are lots of other ways to get more hp for your $$$.

That's just the 3.4 V6? That sounds amazing!
