The argument as to what performance SUV is placed atop the performance pyramid always seems to come to an end when the BMW X5M (or X6M) enters the conversation. The burly vehicles are intimidating due to their size yet still remarkably agile and quick given their heft making them perennial kings of the category. Like their sedan sibling, the M5, however there is a bit missing when it comes to audible enjoyment. While in stock trim the exhaust note is respectable, it is held back from unleashing its true glory in the name of refinement and respectability. Dinan brings forth an exhaust upgrade that retains both these important characteristics but also allows the full chorus of all 8 cylinders to surge through the system and display their vocal talents. With Dinan the beast has found its bark… and it is glorious. To achieve desired sound volume and tone Dinan felt becoming of the F9x X5M/X6M the tubing was enlarged to 83mm (vs 80mm stock) to allow freer flow throughout the entirety of the system. The larger tubing is fed into a muffler that is typical of all Dinan exhaust design and utilizes absorption and reactive technologies designed to improve exhaust flow and reduce backpressure. The combination results in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. This is partly courtesy of the retained computer-controlled exhaust valves that limit noise during low-speed driving and open fully during high-load conditions to allow free flow and greater sound as the bulk of the gases are bypassing the muffler. Like all Dinan exhausts, our X5M/X6M free flow exhaust is engineered to reduce low-RPM drone so the cabin of the vehicle is still intimate and not drowned in an excessively loud tone. With the Dinan exhaust equipped on the X5M/X6M you get the best of both worlds; aggressive tone/sound and civility. A combination that is quintessential of the luxury SUV with a penchant for aggressive behavior. Sound isn't the only aspect of the exhaust that has been modified. The Dinan F9x X5M/X6M exhaust has been skillfully crafted entirely out of T304 stainless steel and TIG welded for the best visual appearance and color. The entire system is then brush finished to further guarantee an immaculate looking system out of the box. The attention to detail is not limited to parts of the system you can't see once the exhaust is installed but is also extended to the exhaust tips themselves. The Dinan exhaust sports massive, quad 4.5" (114mm) clamp-on, double-walled, polished stainless steel and laser engraved exhaust tips that are befitting of the big Bavarian beast. The tips masterfully fill up and accentuate upon the factory cut-outs showcasing an extremely aggressive, yet refined, styling that will force people to take notice even before it is heard.
Features:
- Maximum gains of +6 HP and +5 ft-lb of torque
- Enjoyably louder, sportier sound
- Drone abatement technologies used to reduce cabin resonance
- Four, diffuser filling, 4.5" (114mm) double-walled, polished stainless steel clamp-on tips with laser engraved Dinan logo
- Larger diameter piping for increased flow (83mm vs. 80mm)
- Stock exhaust valve actuators reused, and operation of exhaust valve is unchanged so exhaust tone can be adjusted via the M-drive settings
- Computer controlled exhaust valves are retained and limit noise during low-speed driving and open fully during high-load conditions
- Twin secondary exhaust valves are a whopping 76mm diameter, making them 30% less restrictive than the OE valves
- 100% 304 Stainless Steel construction
- Factory-like fitment with included mounting hardware

Great toy but if your dog is an aggressive chewer, please think twice.
Color: Crinkle Chicken (Brown), Size: Large
I received this on May 23rd and on June 8th, after playing with this thing every day, our recently acquired 36 lb dog finally ripped it open and got out all the plastic and the squeaky part. Lily Belle will miss you, chicken.
Lily loooooved this toy! She'd toss it in the air, chew on it, pull it with her teeth etc. but as much as she loved it, we won't replace it. It's just not durable enough for her.
If your dog is an aggressive chewer, you might want to try a different toy. I hate that this lasted just a smidge over two weeks because Lily seemed to truly enjoy this toy.
RIP, squeaky chicken!

Great New Addition To The Nylabone Line - Perfect for Hard Core Chewers!
Flavor Name: Peanut Butter, Size: Large
We've been using and depending on Nylabone for decades. For more than 50 years these toys have been designed with the dog in mind - and to appeal to their natural instinct to chew and interact. Of course there are the occasional flops but they're few and far between.
We have two Old English Bulldogs, a soon to be nine year old and soon to be two year old. I think out of what stands now at close to 600 reviews half have to be dedicated to dog toys and canine care products. After all, they are indeed family in every sense of the word and we indulge them with a constant parade of new toys.
These new Marrow Barbell bones have been a huge hit.
Both our boys have the jaw power to rip a the door off a Hummer and then proceed to shred the steel. Plush and soft toys are our of the question as those adorable little bunnies and chipmunks, even the ones promoted to hardcore chewers end up looking like road kill in the blur of an eye.
The Barbell design is incredibly heavy and thick - believe me you don't want this one dropped on your foot. Elvis our youngest can do a significant amount of damage in one long term chew session, however after hours of relentless chomping the bone looks unscathed.
Some nice touches are:
* Very Thick casting of the Dura Chew material ( the strongest material made by Nylabone)
* Textured nubs on the outside are superb for cleaning off tarter and keeping your best friends pearly whites and gums in great shape.
* YThe Barbell design makes it easy for yor dog to carry around, providing of course he or she can lift it!
So many fly by night companies cater to "aggressive chewers" and more than often we and our Bullies end up not only destroyed in record time - but can pose a choking hazard and other potentially serious problems. I've had dogs my entire life, over 50 years and I've learned that "Virtually Indestructible' is code for - if lasts an hour you're in luck.
Some exceptions to the rule are Kong for hard core chewers, Planet orbee and of course Nylabone. We used Elk horn for a while until it fractured one of our dogs teeth, not good. Antler of any kind is far too hard a substance and fractured teeth can and do go un-noticed and can lead to infection and blood poisoning.
On a brighter note, the Nylabone Dura Chew has enough give to prevent this - and great lasting power. We have tons of different shapes in the Dura Chew material including the Soupers, rings, Turkey legs and so on. They all hold up and the dogs adore them. Please note, these particular toys are for large breeds with powerful jaws and made especially for the tough, show no mercy, serial killer chewers - canine clients.
And if that my fellow dog lovers fits your pooch you can't go wrong with the Barbell peanut butter Chew Toy.
5 Paws Up!

This is gonna be long, so bear with me.
Flavor Name: Peanut Butter, Size: Large
First of all, I didn't receive the pictured item. I got the "Large" sized barbell chew, and the one pictured is the "mega monster" chew.
This review is for the "mega monster" chew which is what's pictured. I have an 80 pound, 1-year-old lab, and this has actually helped her calm her chewing anxieties. She's become less destructive, and a lot more calmer. She even listens now that her hyper-ness has dwindled down.
The chew I got was the one with the golden retriever- which is the large size. It's the exact same thing and the size I'm reviewing (the one that's pictured with the lab). The one with the 'golden retiever' is recommended for sizes 25-50 pounds. The one I needed (the one that is pictured) is for dogs 50 pounds and up, so it's perfect for my lab. (Are you with me still?)
Anyway, I didn't wanna go through the 'returning and waiting for my new product' process, and I didn't wanna risk getting the same wrong product again. So I just took it to my local pet store and exchanged it for what I wanted in the first place when I ordered this, and paid the difference, which was like 3 bucks.
SO, overall this the quality of this item is amazing! My lab is a strong chewer, and she's entertained herself with this product for long periods of time leaving barely a dent in it. I highly recommend it!
