Production Time: 7 - 10 DAYS Weight: 1.58 Lbs. / 3.48 Kg. Length: 13.78 in. / 350 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: H.224.M3.INOX

Reputable, reasonably priced fuel additive to clean valves, with handy dispenser. Not all comes out.
Size: 300 Milliliter, Size: 300 Milliliter
Honest review of Liqui Moly 2007 Jectron Gasoline Fuel Injection Cleaner - 300 ml , blue @ $8.68 at time of order. I recently acquired a 2002 Ford Taurus with the 3.0L V6 and DOHC. It only had about 131,000 miles on it, but I noticed it seemed like there would be some intermittent misses in the firing. Other than oil changes, I do not believe that this vehicle was mechanically well maintained. After some research and reading reviews of products, I opted to try some injection cleaner as one step in a treatment regimen. I will endeavor to update this review with results after giving it time to work. Likes: Amazon Prime shipping, returns and refunds within 30 days of receipt. Reputable product. The price point seemed reasonable, especially if it works as advertised (10.1 ounces, single treatment can). Comes with dispensing attachment for easier pouring. Dislikes: The design of the can and pouring mechanism left a small amount of product inside the can of valve cleaner. Even completely inverting the can it wouldn’t come out. Granted, it wasn’t a whole lot, but I paid for all of it, not for some left in the can that wouldn’t even shake out. Sorry if this sounds nitpicky, but it is also a problem for disposal afterwards as it has to sit out and evaporate or put it in the trash with flammable liquid inside. Meh: I have put several miles on since adding this to just over a quarter tank of fuel and have not noticed any improvements. I realize it might take a while longer perhaps. Hopefully this honest review helps someone decide about this product.

This stuff really works fast and improves mpg like you won’t believe
Size: 300 Milliliter
I’ve tried many other types of fuel injector cleaners but this brand is amazing. I ran my truck down to less than a quarter of a tank of gas and poured it into the tank. I then drove 30 miles to an appointment and spent an hour in the appointment on the way home I noticed my mpg had gone up significantly. My truck tells me how many miles per gallon. I’m getting as I drive. I had gotten a code and I replaced the mass air filter and found a slight crack in an air hose, which I replaced that help with my code a little bit, but cleaning the fuel injectors with this product made such a significant difference. I just simply had a hard time believing it, but it’s true. I’m done with all those other brands of fuel injector cleaners which never really seemed to help much if you really want an amazing experience give this product to try.
