[B]So what I'm basically reading from just about everyone but cdelena is that one large pipe will flow better than having TRUE duals?

 

I thought that all 5.7L V8 Camaros/Firebirds/TransAms have dual exhaust. Mine did. Only the V6s have single pipes. But to answer Chuck's original question see Mingster's post right below yours. There is no correct answer and no wrong answer it is your own preference.

Some folks prefer dual over single for looks. Some folks prefer single over dual for weight savings. Some folks prefer Ti over Steel. Some want HP for their money some don't care. Some prefer loudness over subtleness. Some folks prefer stock over aftermarket. Some prefer inexpensive over very expensive. There are too many factors for anyone to sway you one way or another choose what you can live with.

 

for something that is not that loud but a much greater sound..
no horsepower gain(no horsepower lose at any range) but reduce weight a lot for dual exhaust set up..!!

 

Chuck,

I don't think you can count on objectivity here People will tend to endorse the things they've bought. I suggest you try to listen yourself to as many exhausts as you can. The best place to do that is an S2000 meet somewhere. I stayed stock for over a year because I wanted to see and hear as many exhausts as possible -- and I did manage to hear most of them. I settled on the Supersprint, but it's expensive and very hard to get. In the end, it's a matter of personal preference, although those who've heard the Supersprint and HKS say the SS is better.

[B]I am thinking about buying new exhaust for my S2000.

 

Chuck, why don't you post this in the North Texas forum b/c there's a couple of us that have different aftermarket exhausts. We've all heard them in person & perhaps you can too if you join us sometime. Here's some of the local guys & what they have:

cdelena: Mugen
jk: HKS Hiper
Svann: HKS Hiper
Elistan: J's Racing N1
Myself: Amuse N1
RedDevils2k: RM Racing (B&B Tri-Flo)

I dont' mean to be rude but I had 2 camaro's (please don't ask why ) I had a '96 Z28 and a '97 30th Anniversary SS (350hp stock).. They both had dual pipes out the back. If you get UNDER the car, it is one muffler with 2 pipes coming out of it. The Firebird/Firehawk/Trans Am/Z28/SS/White Trash (j/k) are all the same. One pipe coming out of the cat back to One muffler to two pipes on each side of the back of the car. I would never say that one pipe is better than one, just for Normal Performance (not FIA Sportscar performance), one pipe is not the enemy.. The Vette does have 2 mufflers and so does the mustang.. hehe.. I would never go one pipe on my S2k though..

 

I am a retard.. I meant to say "two"

 

The 2 pipe vs. one pipe debate:

I'm a mechanical engineer, so I've taken courses in fluid mechanics. The better of a dual or single exhaust system will come down to who put together the better design, every time. By this I mean which engineering group went through more design iterations with YOUR personal criteria in mind. And more design iterations means longer payroll and a higher net cost. The largest contributors to the airflow and hp gains will be (in no particular order) the cross sectional area of the pipe, the friction on the internal surface, and the number and angles of bends in the pipe. I've never checked the Reynolds numbers, but I assume flow through exhaust is fully turbulent, so this internal friction has much less effect than it could. My text is at work, but from memory a 45 degree bend has about a fifth the impeding impact as a 90 degree bend on flow. I could look this all up and quantify it as flow resistance if anybody really cares.

But the bottom line is, the better pipe has less to do with whether it's a single 4" or dual 2.50" and much more to do with how well the company put it together and how closely their success criteria (sound, power, etc) coincides with your own.
