The exhaust has a removable db killer (noise restrictor) for racing use. Removing the DB Killer is ILLEGAL and the customer assumes the responsibility if they use the motorbike as on the circuits only, without bags, without flash lights, number plate holder or other parts that would conflict with the different angle of the gas following the transformation into the racing version. Abuse of this situation on the road will result in the loss of the product warranty and any refund request will be rejected.
The warranty is two years from the purchase, with right of reparation with a return to the GPR factory, or the nearest official distributor at the customer's expense.
GPR will not provide a new silencer, but will repair the original silencer. The customer must accept to remount the original exhaust or wait the standard time for the repair.
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.
RACING PRODUCT: This exhaust is supplied with a removable DB Killer. However, it is a RACING product and is not legal for road use.
This kit does not include a catalyst.
In some cases, the use of racing items may require the remapping of the ECU, especially when there are additional modifications, such as the installation of a sports filter.
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 for your road network.

A staple in my pocket!
Format: Paperback
I’m a PA student in clinical rotations. This book helped me survive my ER rotation by guiding me with high yield information, differentials, physical exam and history to obtain. Love that it helps give insight on when to admit vs discharge in the treatment plan. Applicable across the board in family med, urgent care and other clinical settings other than ER too. I recommend this book to all students! My preceptors were very impressed in my thought processes and I have this book to thanks for that. I’ll be using this book throughout my career!

Straight to the point and everything you need
Format: Paperback
EMRA products never disappoint. I hardly leave reviews but this company makes the best resource materials out there. They have managed to distill down to the most important info needed to diagnose treat , and work up most diseases that present to the ED. I also have their quick pocket reference and I love those too. Only thing I would change is make the writing a but bigger. As one gets older it's hard to see
