The exhaust was installed on a crypton 105 98' completely original, as it is from the factory and according to its code (Apido SRL-Z) it is for this specific bike.
QUALITY: for the 60 euros I paid for it, it has a mediocre construction quality, I can say acceptable. It weighs 1660g, compared to the genuine one that weighs 3560g. I have a gain of about 2kg. Nice lines, mediocre paint quality, which has turned gray after 200 kilometers. I have no complaints about the price I paid, although 2 years ago the price was 50 euros.

SOUND: the sound, even with the baffle, is quite loud and a bit annoying for my taste. It doesn't sound bad although it lacks bass. It sounds a bit high-pitched and dry, but if you remove the baffle, the sound changes. It becomes deeper and bassier, quite nice! Maybe even a bit louder.

INSTALLATION: here it is a bit of a hassle!! Although I thought it was plug and play because I bought the code for my bike, it's not like that. It requires hitting, bending, spacers, and improvisation to stabilize it, as it doesn't fit on the existing base of the old exhaust. I had to mount it in another spot as you can see in the photo. Nevertheless, it tends to look a bit outward as shown in the photo and due to the pulling, it also needs a washer between the neck and the cylinder to prevent leakage. The washer is not included in the package, it would be good to get it as an extra.

PERFORMANCE: And yet, I noticed a difference!!! Although I wanted to remove it because it had a loud noise, even with the baffle, I kept it because the difference in performance was evident! It doesn't set the asphalt on fire, but I definitely felt a boost, especially in the mid-range RPMs. In the high RPMs, it doesn't do anything, I have the same top speed. But in the mid-range, it took off. While before I would shift to 3rd gear at 45km/h, now I can easily go with 4th gear. It has a positive increase in RPMs. Also, I got the impression that the engine doesn't work as "tight" anymore. The tests were done with the throttle limiter. Removing it, I didn't see any further improvement.

SUMMARY:
NEGATIVES: mediocre construction quality, some difficulty in installation, loud and annoying sound.
POSITIVES: very good performance, lightweight, beautiful exhaust, decent price.
