Production Time: 7 - 10 DAYS Weight: 2.27 Lbs. / 5 Kg. Length: 15.75 in. / 400 mm. GPR's Trioval series is a GPR best-seller, with a classic ovoid drop shape. It is made of hand-polished 304 stainless steel and has a diameter of 3.9 inches x 5.1 inches (100MM x 130MM). FEATURES • SOUND: Upgraded sound from stock exhaust. Although louder than stock, this exhaust produces the softest sound of all the GPR exhausts. • 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: Y.135.TRI

ASICS shoes never disappoint
Size: 10.5, Color: Cool Grey/White
My husband has run in Asics for years. He usually gets another style but decided to try the Excite because they were on sale. The material in the uppers is very breathable which is nice on hot days. They also have a very stable, thick sole which is perfect for running on asphalt. Generally we don’t walk in our running shoes but on a recent vacation he only had these sneakers so spent a lot of time walking around and they remained incredibly comfy! The Excite seem a bit more narrow in the toe box but otherwise run true to size. We would order them again!

Take my advice, upsize half size bigger
Size: 11.5, Color: Winter Sea/Black
I need to start suggesting everyone that owns Gel-Kayano, Gel-Cumulus and/or GT-1000 14, that if for example you wear US men's size 11 with these, order 11.5 in Gel-Excite 11. When I did a search using AI for getting suggestions on the fitment and sizing of the Gel-Excite's 11, I got 'order half size up' in all results, I was a little skeptical but I follow the suggestions and I'm glad I did because no way that size 11 would've fit me, 11.5 fit me perfectly as the Gel-Kayano 32 in size 11. I've just tried these one, so far I feel them comfortable, I walked for 5K steps and haven't had any discomfort with my flat feet and the issue I have with my left knee patellar tendon. I stood up for 30 minutes while I waited for my car at the carwash, no issues. Time will tell about durability, but I can say the looks and comfort are pretty good for such a budget shoe.
