This kit includes the specific lnik pipe or half-manifold with specific appropriate brackets and accessories. This allows for installation without any structural modifications.
To install, no structural modifications are required. GPR recommends reading the included instructions or tutorial on http://www.gpr.it or the GPR channel on Youtube.
For on-line purchases, activate the warranty by sending the installation receipt from the mechanic / shop via email to [email protected], or sending the sales receipt from the physical or online store.
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.
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]

Comfy cute boyshorts
Color: Multicolor-4pack-a1, Size: Medium
The boyshorts are so comfy,true to size & good support. The waistband doesn't curl,has a no show look & is good for Everyday wear. The colors are nice, doesn't fade in wash or shrink in the dryer. The material feels good & is lightweight. I highly recommend trying these boyshorts at the reasonable price.

Not all cotton panty.
Color: Multicolor-4pack-a1, Size: Large, Color: Multicolor-4pack-a1, Size: Large
These are comfortable. I weight 150 lbs normally I wear a size large. I ordered large. They fit good because they stretch. They are not tight, just comfy. I think if I ordered an X-lg they would feel more like my regular panties. Giving me a little more room. Also…I was under the impression that they mostly made with cotton. The crotch is the only thing that’s 100% cotton. I’ve attached a photo of the material content. I’ll be looking for another boxer brand that is all cotton.
