That thing sounds wicked!

Hmm..
 

Kind of sounds like this:

This build is why I joined this forum. So freakin' awesome!!!

I have a few questions about the exhaust:

1) Why the 180 degree headers?

As he owner of probably the only other FRONT engine car here (Panteras don't count), I am very curious why you would do something so unusual.

2) When are you going to post something so we can here what it REALLY sounds like--beyond a start up and a few revs?

I am dying to hear this thing moving under its own power. A lot of people hate how mine sounds, but you can't do anything different without upsetting at least half the people out there, right?

3) Can I PM you with a bunch of specific questions on the header design once I get a good listen?

Meanwhile, here are a few pics of mine:

Mark, did you build your own 180° headers? Those are slick.

And yes, a lot of "American muscle" type guys are not going to like the sound of 180° headers. They get rid of that distinct American V8 sound. Anyone that gets all hot-and-bothered by a lumpy cam is going to think that a car with 180° headers sounds like a sewing machine.

On a different forum, someone posted a clip of the new Ford "voodoo" engine, with its flat-plane crankshaft... so it has an exhaust note like 180° headers. Anyways, there were people who said that it sounds "rice", because they are used to the uneven chugging of a typical American bent crank motor.

I prefer quiet exhaust, so my opinion is far from the average. I do like the scavenging effects of the 180° headers, but I can't get behind dry-sump oiling so packaging becomes a problem. I guess I am stuck with the rest of us mere mortals, and I will have to settle for some Tri-Y's.

Mark,
cool job on the headers...as far as 180 headers sounding
like sewing machines.... if on a Pantera you split them far apart
they really do not sound that great... I have tried to record
my Pantera with the 4" straight pipes and the Iphone shuts the
sound off.. I guess 109.7 db is too much.. 105 with my street pipes
and maybe 98 with my California Track pipes
We have three Panteras in my shop all with 180 headers and they
all have a distinct sound.. one is a Cleveland with a roller, the other
is a Stroked windsor with a roller cam and turn downs on the ends
and mine is a Stroked windsor with a solid lifter cam.. none of these
sound like sewing machines trust me.. like a V8 at idle

Look on this site "Members on the Scene" and go to the post Sieg did
6-2-2014 Labeled a few Autocross Launches.. my Pantera with 180s'
You should hear it with 4" straight pipes.. actually ordering conicals to
go down to 3" at the ends to try and put a little back pressure in them
before I go to TWS next month

Rampage really hits hard

Mark when can I send my bird over for the header mods:)
would love to do it on the bird but not a lot of room
Herb Adams modified his Oil Pan to get them on his first Firebird

Pic of my Pantera headers... easy compared to what you did

Gonna have to disagree with most of this.
I ran 180* headers on some of my race cars, and they in no way get rid of the distinct american sound. Perhaps your mistaking 180* headers for something else. Sewing machine? Really?
The flat plane engines produce a unique sound of their own. Sounds nothing like a set of 180* headers really. They are probably referring to the ricer term, due to Italian built cars making that sound, because most come with a flat plane crankshaft.

any updates?

haa saw that on IG, my wifes new ring tone



awesome car!!!!!
