Production Time: 7 - 10 DAYS Weight: 1.35 Lbs. / 2.98 Kg. Length: 11.81 in. / 300 mm. GPR developed the M3 Inox after the victories in the Moto3 World Championship. It has a removable racing grill and CNC-machined bottoms. It has a hand-brushed stainless steel body, and a round shape with a diameter of 3.9 inches (100MM). FEATURES • SOUND: Upgraded sound from stock exhaust. • PERFORMANCE: Upgraded performance from stock exhaust • QUALITY: Italian made with high-grade welding • WEIGHT: Lighter than stock exhaust 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] Reference: E4.KT.87.M3.INOX

Very stylish and extremely comfortable. It feels like you're walking on a cloud! It is made of great and strudy material and the quality is excellent. My size also fit me perfectly. I would definitely buy it again.

Insoles suggested.
Size: 12, Color: All Black
Nice, business-style, soft, shiny, leather-like material, extremely light and well cushioned all around. But, there is little or no arch support, which make these shoes NOT for all day wear, unless an insole is inserted. The slip resistance is not great, but acceptable. Still, very good for the price.

Great shoes!!
Size: 8.5, Color: All Black
Really comfortable I feel like I’m walk on a cloud. In terms of the shoe quality, I work in these for retail, they do crease quickly within 2-3 days. They fit true to size.
