This is not a plug-and-play installation. Due to the complexity, the installation requires a professional shop that specializes in Cafè Racers. The installation requires installing, cutting the original header and creating the connection to the silencer directly on the motorbike. This kit does not include link pipes, and the professional mechanic must manufacture or create a link pipe and fitting.
This is a universal kit, designed for transformations and customizations. Because it does not include link pipes or brackets, it requires changes to the manifold for proper installation.
This is an original GPR product, developed after GPR's experience in the World Championship. It offers an innovative design, improved performance, weight savings and a full-bodied sound.
Made in Italy with a 2-year international warranty.
Tampering with the DB Killer welding or antitampering screws or fastener is illegal for road use within the EU directives. It is permitted only for RACING use in the circuits. The use of the open version (without the DB Killer) on roads does not comply with regulations governing circulation on the public road network.
This kit is homologated for noise only. Please check whether a catalyst is necessary within your country to be road-legal and to pass any local inspections.
GPR Products are plug-and-play. However, we do recommend a professional installation.
If you buy online from a seller that is NOT GPR, we recommend you buy from a seller in YOUR COUNTRY to ensure that the item arrives with the correct approvals that must also comply with local legislation. Make sure before purchasing that the seller is trustworthy and offers the items that comply your road network.
Each package includes the homologation certificate, assembly instructions, and a homologation code on each silencer.
In case of a problem during installation, please stop the installation process and immediately contact customer care via email at [email protected]
Requires cutting the original header

Durable for Heavy Chewing Rottweiler
Fit for Rottweiler, indestructible and ordered the Y stick from them as well! Lasted longer than any other toy I’ve given her. Kong who?

Soccer pups
Color: Green-M
This one is a must toy for the pup who loves to chase balls and chew. I bought one for our pup and our daughter's pup. Both have a blast with it and so do the adults.
The only improvement I would make is the straps need to be more durable- they haven't frayed which is good for the pup who likes to chew everything, but some have torn. The ball itself has stayed intact though; its fairly bouncy too; which makes for fun times

My Great Dane loves this ball! It is sturdy and fun for her; she can pick it up by the tabs as well as grab the whole ball.

Great toy:) but doesn't last long
Color: Green-M
This ball was actually really great!. I bought a few different toy balls for our puppy to play with and Aka (our puppy) found this one to be the best. Aka loves carrying things with his mouth. I also think he found it enjoyable, with all the pull tabs, to carry this ball around instead of trying to fit it in his mouth. I waited around 2 weeks to write this since that's how long it took Aka to destroy the ball:) At least it wasn't within the first day. We have a bigger dog an American Bulldog that's about 90lbs and he punctured this ball within the first day but it held up for a little. It's the same as a soccer ball really, not super tough and if you have dogs with big bite forces that are heavy chewers they'll destroy this so fast! But i like the design of this toy and I think it made a great toy while it lasted! It did deflate when it got punctured and held some air for about a week. With constant play it deflated completely after that. It was also the same size as a soccer ball.

Fun toy for dogs that like to fetch
Color: Green-M
The toy is great, good quality, and durable. My dog will only play with it if I am am playing with her, otherwise she loses interest and that is why I am giving it a 4 out of 5. She is a 60 lb. dog and the size. It is a good price for the product and when my dog does play with it the multiple tabs on it make it user friendly for chewing and tossing.
