Dinan Free Flow Axle-Back Exhaust - Mini / F55 / Cooper S 5 DoorDinan engineers designed the F55 MINI Cooper S exhaust to improve exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. Like all Dinan exhausts, our F55 Free Flow Axle Back Exhaust is engineered to combat low RPM drone so the cabin of the vehicle is still intimate and not drowned in an excessively loud tone. The
Dinan engineers designed the F55 MINI Cooper S exhaust to improve exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. Like all Dinan exhausts, our F55 Free Flow Axle-Back Exhaust is engineered to combat low-RPM drone so the cabin of the vehicle is still intimate and not drowned in an excessively loud tone.
The system is built with ease in mind and utilizes a simple bolt-on installation with included mounting hardware. It is made from 100% 16-gauge 304 stainless steel and will resist corrosion for years to come. The design features twin 90 mm ceramic black and laser engraved exhaust tips for a tasteful, high-performance look that yields a maximum performance gain of 4 horsepower and 4 ft-lbs of torque.
NOTE: The exhaust system is only offered with black tips as one of the tips is non-functional and would lead to non-matching discoloration over time if polished tips were used.

My Lexi loves them!
Size: 1 Count (Pack of 16)
I myself have never tasted them or chewed them, but my dog Lexi goes crazy over them. I insert them into her chew toy puzzle and she is in heaven! the quality is good. the only problem with them is that my Lexi loves them so much! he is constantly bringing her chew toy over for a refill. again! Lets do it again!

Best dog toys for active dogs!
Size: 1 Count (Pack of 16), Size: 1 Count (Pack of 16)
A while ago we bought the ball bone toy for our dog but after trips to 4 different pet stores we were unable to find the replacement rings. Imagine my joy when I found them on Amazon for about $5! It's money well spent, our dog is happy and so are we! They are long lasting (about an hour for our most determined dog) and are easy to replace in the toy. Word of caution, sometimes bits of the treats get stuck in the grooves of the toy or under the ball, make sure you take the whole thing apart and wash it well before replacing the treats. So far this is the BEST toy to distract our curious overactive pup. We'll keep buying them. Look at this happy pup!

Longer Lasting than most things I've tried
Size: 1 Count (Pack of 16)
I bought these to go on the PetSafe Bouncy Bone which I had bought for my Australian Shepherd/Vizsla mix puppy who chews everything. We had gone through so many "long-lasting" chew toys/bones that really lasted only about 10 minutes and I was looking for something to occupy his time a little longer. These do the trick. Although they still don't last super long, they take a little more effort and keep him distracted a bit longer than anything else edible that I've tried. To me they are a bit pricey, so I try to make them last by only putting one on at a time, instead of one on each end of the toy. I also tighten the ends pretty tight to make it more difficult for him to get at the entire ring. If you don't mind the price, these are an easy and convenient way to keep your dog busy.
