Full system carbon fibre shortie twin exhaust for Hyosung GT650

[John_H]

Brand new full system, Still in packaging. Sounds amazing, looks very cool. Picture is similar to this system on sale. More pics to come.

Those pipes are tiny! sure it's for a 650?

Size of pipes has nothing to do with what bike they are for. You can have small bikes with big pipes or big bikes with small pipes..and so on.

The system looks very cool, kinda like an rs-4 twin system from yoshi.

How do you know it sounds amazing if it's still in the packaging? :blink::mellow:

Because I have seen the same system on another bike. Thanks for your input.

[John_H]

Pipes now sold. Thanks!

Err, yes it does.
Two strokes have tiny pipes. Small 4 strokes have small pipes. Large 4 strokes have large pipes. It's all about airflow and backpressure. A big bike with a small pipe is going to be seriously restricted...

It has two exits and the stock bike one, from the link/collector box those are definitly a smaller diameter than stock, dare I say perhaps about maybe half? We can't see the headers but i'd guess they are about the same as stock.

Nice looking system, and a cheap one too!

All good, I was taking the piss... please come again :)

And if you look really closely (those of you that know your Hyosungs), you will see that the bike in the picture is a GT250R. Perhaps why it has smaller pipes.....

If you put on your glasses and look even closer it actually says GT 125 R :blink:

[Wannabiker]

So it does. You obviously know yout Hyosungs :innocent: I was just going off the frame. Single rectangular tube, not twin round tube of the 650.

I had heard they did a 125...

[Lurch]

My god. Can you imagine the scooter-like feel of a 125 hyosung!?!

[Slyer]

This would explain the tiny pipes. :bleh:
Why the hell would you want one, the exact same handling characteristics but half the power. =/

Still, the one that was for sale could hardly be called "similar" lol.

fuel injected 125 v-twin, what a bucket racer that would make!

It would be a very impressive 3 or 4 laps.

Dry mass of 166 kgs and 14.5 hp. Hmmmm

Sigh. Its mainly about header pipe design.

A lot of the time it boils down to emissions control and noise control.

Someone tell the guys at yamaha, honda and suzuki they have it wrong, they need to chuck a bigger pipe on it.

Sigh @ you. I AM talking about header pipes. Did I say anything about exhaust, can or muffler?

All good bro. But this system from the Hyobag 125 on your old CBR11000XX overkill and see how it runs.

It's actually more about airflow, exhaust velocities, back pressure and a myriad of other things. But bottom line is that if the internal diameter of an exhaust pipe is too big or too small then you're bike will run like a bag of shit and ultimately you will lose power and potentially over time cause excessive and unnecessary wear to your engine.

Sorry sam, I assumed from your wording here that you were talking about mufflers; otherwise it still isn't making sense, two stroke pipes headers and expansion chambers are definately not always small on small capacity two strokes, neither neccessarily are their mufflers (gt750s dont have small pipes).

I was merely saying you cannot use big or small as dimensional guidelines based on capacticy. I won't continue typing, you are a smart lad. You can think up some examples.

It is like saying (and I apologise for the racial sterotyping) that all asians have tiny penises, all white poeple have small penises compared to african americans who have big penises.

Note: I wasn't referring to the picture of the gtr250 at all in my comments

I didnt say ti would dude, I was just saying that you can't generalise like how sam did.
