would be badass!

It's way more efficient. The staggared sound pulses actually suck the exhaust out from the opposite bank. It's something domestic v8 guys have known for a long time.

[Gocasen]

Yea i know that but i was hoping it would work similar to the inline four. Were the header for each bank oppossed eachother. But guess they run off the second bank also.

[Weasy2k]

inline 4 still connects 4 2 and 1

[Gocasen]

I know but i was thinking that each bank (123 and 456) were serprate and independent of the other. And i was hoping i could just cut the bs and go straight off each bank solo. You know. But i guess it was designed to go off the other bank.

[Oteck]

it actualy goes like 1,3,5 and 2,4,6 per bank

[Gocasen]

I am just making assumptions to get my points across

My turbo resonates at 70. Its really annoying! I put on a couple resonator tips, but it didn't help much. Don't know what to do. Different muffs?

4" Turbo-back (if I can get the piping to fit, otherwise Ill have to go 3") into a 4" ID bullet muffler.

"Radio?" What? You'll have to speak up over my exhaust...

*edit*

And the muffler will be center-exit. I have a photoshop I did but I cant remember the URL on my site so Ill have to find it later, heh.

how did ferrari get their V8's to sound like the V10s....stuff like that...

I think it had something to do with them using flat cranks....I heard this many years ago and my memory is starting to fade me.

The truck sound comes from large displacement and low revs. http://www.v6mr2.com/V6t.wmv you can hear under heavy load and low revs it ideed sounds like a truck or muscle car. Once the revs pick up the engine sounds awsome. Its ALL ABOUT THE REVS!


BTW: max revs at any given point in that video were not above 5600ish immagine the sound at 7500 or 8000! I think the truck sound at idle is unavoidable with out a restrictive exhaust. It is, after all a V6.

[Weasy2k]

hehehe i cant wait to spin this one up there!

Fixed

Is it possilbe to do a true-dual setup and avoid a y-pipe at all? Just 2 seperate exhausts straight off the headers? I think this would sound mean...I love the muscle sound, haha.

[Node]

You actually want the two exhaust streams to cross. There is a noticeable gain in torque on the lower end from the use of an X pipe.

[JMcDonald]

Plus, IMO, true-dual exhausts sound like ass. More exhaust pulses generally means higher pitch all else being equal. If you separate the pulses it will sound like two 3-cyl cars running next to eachother. That is why most TT 350zs still have that deep cow-like pitch even as they approach redline. There simply arent enough pulses to raise the pitch. This is also why I-6s tend to sound so high pitched, because all the exhaust pulses go through the same place. Take a 350z and make it single turbo, and you get nearly the same sound. Also note Vipers. They tend to have a pitch kindof between a 4-cyl and a 6-cyl... like two 5-cyls. Get what Im trying to say? Keep those pulses together!

At least this is all what I've noticed.

[PearlJammzz]

I have heard some old muscle cars w/ true dual all the way back and it sounds sick as ****, lol. Not sure how a 6 would sound.

Why does the cross cause torque? Just create back pressure but still allow the air to flow well?

[Gimpster]

IMO, nothing sounds better than a V8 with an H or X pipe Just staight "duals" always sounds weird to me, and I can pick those car out easy (as they're usually quite a bit LOUDER). They usually sound like 1978 Ford trucks with unconnected cherry bombs

It should be noted you want to use an X pipe like Node said. An H pipe does a good job of balancing the sound pulses, but doesn't scavenge very well (air takes the path of least resistance). The whole point of connecting the cyl banks is to scavenge/smooth out pulses.

I have been trying to figure out any way to run exhaust with a little more generally avaliable muffler. I have been looking into the 350z exhaust, but after looking at some pictures I think that it may be too tall to fit under our cars. I made a drawing of an idea I had and its crude and not to scale but I am wondering if its even possible. I realize that the exhaust tips are not equal length but this type of muffler is easily avaliable and cheap.

[singleslammer]

I have another idea. Alright, flowmaster makes a replacement muffler for an 82-2002 camaro that is very similar to our stock mufflers. It has dimensions of 4x9.75x15 and has an in and out on one side and an out on the other side. you can get either a 2.5 in/out or a 3 in and 2.5 outs. I really want to keep the exhaust as stocking looking as possible. I am not a fan of the canister look and really havent found any aftermarket exhaust that I like.
