What is that third outlet coming out of the pipe? the one coming out of the middle if its not obvious enough.

 

I bet it's some form of "noise maker", or a way to bypass the muffler. Not sure I'd want either one, but you've piqued my interest. I've not heard of this brand yet, but that doesn't mean a whole lot. I'm a newbie to car tweaks.

 

As I recall, this was discussed a while back, and the consensus was that it was a resonant tuning pipe of some sort, to "tune" the tone and volume.

 

that's very strange. it looks like a cutout, but i don't see a valve. if it's just "there" all the exhaust is going to go out that hole instead of through the restrictive muffler.

 

Exactly, path of least resistance and all... I'd love to hear from KS as to what the purpose is

 

If it were a cutout, it would have to have some sort of an attachment points on it for the cap, and it wouldn't be chromed. I vote for resonance chamber.

Or maybe, it's a drain clean out point like household pumbing has... way to get rid of all the soot that must accumulate inside of all of our exhausts! :D

 

Wow, that is one mutant exhaust!

 

hmm maybe rotarygod or wakeech can enlighten us

 

I also think it is a resonance chamber.

 

yeah, that's a really old picture. being that i haven't seen any new info on it, i can only guess as well as you.

i'm not sure that it would be legal for that to be an open outlet (and to me, is about as cool as taking a screwdriver and putting holes in your muffler)... it would be loud as hell, and idling you'd probably end up with exhaust getting up underneath the rear passenger seat.

BUT, what is interesting is how the tubing is bent to go around the long way to have a larger radius through the bends (meaning higher maintained velocity, less energy consuming).

 

In the mid 20th century some exhaust systems utilized what were know as "exhaust boxes". They were just dead end pipes that led to a muffler like device to help control tone. Usually they were just a single open chamber. Size depended upon what the end goals were. They did do a little for muffling but they are best for just tuning out certain resonances. Knight Sports probably had a very annoying tone at a certain frequency and couldn't get rid of it easily. This is most likely a chamber rather than an outlet. I don't think that any company would market a cutout without some form of blocking it off.

 

HA!!! Toldya so! :D

 

so this exhaust is really expensive, i was looking at it the other day. Does anyone have it?

 

Not on this forum I believe.

but if you go on to Japanese sites, TONS of people have that exhaust.

 

do they say its any good?
