It's so good!

This Exhaust System is the best!
? sound good
? Good shape.
Cost is good among the products for zx25r

Even if you don't pull out the Baffle, it sounds great. It sounds even better when you run it to the point of burning!
If I pull out Baffle and run... It sounds too good to be true, and I don't want to get a fan and have to ask for Sign, so I don't.

(I didn't want to use the normal tandem step, so it can be added to the exhaust bracket of the Trickster, but it will push the exhaust system up a bit.) You're on your own. View detail

It's loud, but it's great.

It is an explosive I'm a little more careful when I run at night...
If you're looking for sound, you can't go wrong with this one.
If you drive on a mountain pass, the sound echoes and it's really good (vocabulary)
Tunnel... Oh, my... It's... It's great.

Gasket is not included, so you need to order it from Manufacturer. View detail

Increased performance, reduced weight

Good in general.
From a performance point of view, you can feel the power from the low speed, which may be due to the weight reduction.
Of course the high rpm extension is also better.
Power up in the whole range? Speaking of
There is a trough of Torque around 9000-10000rpm.
It is a little Stress.
However, with the For Racing Exhaust System, if you are able to maintain a higher RPM than that, you can.
It's not a particular problem.
Power will also change with or without the included Baffle.

I haven't heard anything else about the sound quality, but... (It may be a personal thing.) With Baffle, there is a little low-mid rpm and grating component.
It's quite a blast if you take the Baffle.

As for the installation, the joint is quite hard and the alignment is Large strange.
The Instruction Manual is rather solid, so it is best to follow the instructions faithfully. View detail
