Yeah, that does seem odd, but I think they just used dual tip muffs for the show. Maybe the custom ones weren't ready in time. :scratch: At least that's what I hope.

 

but the dualtips are still connected to the mufflers It doesn't make any sense to me :scratch:

 

would it have been that hard to make it real?

 

I believe it. For some reason I think if they bent the tubes properly to get it out the back (where they have them in the middle) they would lose some horse power. Then again, I could be way off.

 

the pipes in back are because , being a manufacturer rather than a tuner, they have to meet noise regulations. the turndowns are controlled by some kind of bypass valve judged off of exhaust pressure. so, theyre all real

 

yeah, i saw this for a second on another thread. the back pipes ae always functional, at high power a valve opens up the second set of pipes to allow better exhaust flow. they are turned downward to quiet them down.

 

A bypass valve in the muffler? :scratch:

I'm a little skeptical on that.

 

You know, I dont really LOVE any single car from the SEMA show... I could probably build a perfect one using different parts from each..

Most are too gawdy to me... Just my opinion of course. Like take the rear end of the saleen. The blacked out bar in the tailights seems lame to me... Like its done just to be different SOMEHOW...

There was a thread about this on Stangnet. The bypass is supposed to open on WOT and reduce backpressure. They're turned down to reduce noise.

 

If you go to the Saleen website and click the link that shows the introduction of the car by steve saleen at one of the auto show and watch the clip he talks about the bypass valve and talk about how it is better because you have good torque at high rpm along with high horsepower...or soemthing like that But anyway go watch the clip it explains it all....

 

Thanks!

I'm a :geek: I like to know how things work.

 

That is the single cheesiest exhaust i have ever seen bar none.
The HP gains he mentions are more than likly lost with all the extra weight of the metal to make that exhaust. I'm sure it's not much in the gaines dept. Certainly not worth the rediculousness of it.

Once again Saleen have proven to me that thier slogan should be "Bad taste in the hands of a few" Goodnight! eace:

no offense to yo0u saleen fans out there..these are just my opinions

 

hmmm.... thats odd

 

here's how the exhaust works, and this may be why and when.... if you dump all of your backpressure, you lose your bottom end torque, but if your pipes are constrictive, you lose your ability to breath on the top end.... so I'm assuming it's closed on the bottom end to allow for more bottom torque and opens at higher RPMs at WOT to accelerate the ehaust and allow the engine to breath..... for higher peak hp.

 

The Saleen system is essentially the same all the way to mufflers. The only difference is th mufflers themselves and the extra tips sticking out the back? How much do figure the mufflers and the extra tips weigh?

 

Below is the atircle from fast-autos.net

Innovative Exhaust System

The exhaust system is an innovative "variable design," featuring twin mufflers with vacuum-actuated valves that open above a specified back pressure. When these valves open, a portion of the exhaust gases is routed through a second set of tail pipes pointed at the ground. This design offers numerous advantages. It allows the engine to be calibrated to produce higher torque. Secondly, it provides a free-flowing exhaust system, while still providing the capability for passing mandated pass-by noise regulations in the U.S., Canada, and U.K. Thirdly, it makes for some lovely exhaust sounds at wide-open throttle. The exhaust side of the engine also features a full 2 ½ inch stainless steel exhaust system, running from the exhaust manifold outlet to the tip of the exhaust pipes.

I think he put it in to prove a point. The added weight is probably not that much (if any at all) and the system probably do benefit performance. But hey if you don't like it, you don't. To each, their own.

 

does look wierd though.
in the first picture the big pipe that curves and connects the two muffelers looks like it is not even open to the two center tips.
or is that just me?

 

ding! ding! I think we have a winner.
