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]

Shocked
Color: White, Size: Queen (Pack of 2)
I'm really bougie when it comes to pillows. I've never spent less than $50 on a pillow. I'm a side sleeper and like firm support, but also want something soft. I almost ordered the really pricey pillows on Amazon, but was turned off by all the odor complaints. I needed something quick to at least hold me over until I could get exactly what I want, so I took a shot with this pillow with the plan of it being a temporary fix. However, this pillow turned out to be exactly what I was looking for. The first time I laid on it I was skeptical. It had support, but felt like it may have been too soft. It took a bit to get accustomed to, but by the second night I knew this is the pillow. No chemical odors, it's quality at a low cost. I figured this pillow would've been quickly replaced and put into the leg pillow rotation, but it is shockingly a really great pillow. It is not lumpy, stays way cooler than standard or shredded memory foam and is comfy. Hopefully it holds up for a long time. I've paid triple what these 2 pillows cost for a single pillow that isn't as good.

Favorite pillows
Color: White, Size: Queen (Pack of 2)
These pillows are amazing! They are huge and plush but you can change that if you prefer. I really like that the outside cover can be washed and is also filled. It held up great in the washer and dryer. I just followed the directions on the tag. Great price for the quality and look very nice and fluffed on the bed.

Good option
Color: White, Size: Body(Pack of 1)
I’ve been using the ACCURATEX Full Body Pillow for Adults – Hybrid Shredded Memory Foam for a few weeks now, and overall I’m really happy with it. The blend of shredded memory foam gives it a firm, supportive feel, but what I love most is that you can adjust the filling to get the exact firmness you want. Whether you prefer something more structured or slightly softer, it’s easy to customize by adding or removing foam.
Comfort-wise, it’s definitely a step up from standard body pillows. It keeps its shape throughout the night and offers great support for side sleeping. That said, it is a bit firmer out of the box than I expected, which is why I’m giving it 4 stars instead of 5.
If you’re looking for a body pillow that won’t go flat and lets you tweak the feel to your liking, this one is a solid choice.

Favorite pillow!!
Color: White, Size: Body(Pack of 1)
I honestly wasn’t expecting to love this pillow as much as I do. Buying pillows online always feels risky because you can’t actually feel them beforehand, but this ended up being one of the best blind buys I’ve made on Amazon. The quality is genuinely shocking for the price. It feels way more expensive than it is. It’s insanely comfortable, supportive without feeling stiff, and just has that “perfect” cozy feel. I have neck problems, so I’m really picky about pillows, and this one somehow manages to be the perfect balance. It’s supportive without being stiff or overstuffed, but also not too flat where your neck feels unsupported. It has that perfect “sink in but still supportive” feel that’s hard to find. I loved the body pillow version so much that less than a week later I’m already ordering the regular pillow version too. Easily 5 stars from me!!

Probably going to replace all the pillows in the house with these
Color: White, Size: King (Pack of 2)
These pillows are just about perfect. They have to be the best pillow for the money out there at least. I didn't even know that this kind of pillow existed but was asking Google Gemini what kind of pillow would best suit my list of needs and this is what we came up with.
- High loft for comfortable side sleeping, but can be reduced by removing foam to be less high
- Gives initially, but stays at that new same thickness throughout the night b/c it's memory foam chunks
- Doesn't feel lumpy because it has the 1cm outer pillow layer that covers the memory foam pieces
I'm 6/3" 210lbs and after a couple nights of adjusting I found that removing about 1 gallon ziploc of foam chunks from each pillow was about perfect. I saved the foam in ziplocs in case I change my mind. They come REALLY loaded at first so should fit literally anyone with some adjusting. It was definitely too big the first two nights until I got it just right.
