Overview:
The American Thunder® Crossmember-Back exhaust system is a true dual large 3.00-inch muscle car system for the person who is looking for a deep aggressive sound for their high horsepower vehicle. This stainless steel system is mandrel-bent for maximum performance, includes an H-pipe crossover to balance out the exhaust pressures, add hp and torque, and to help eliminate back-rap on deceleration. The specially selected Super 40® Series performance mufflers feature a large case to handle the added horsepower and provide a deep muscular tone flowing through the large 3.00-inch tailpipes. The American Thunder systems generally deliver an aggressive interior and exterior tone and are suited to the enthusiast who wants their performance to be heard. The sound level will depend greatly on the engine and level of modifications. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, these systems include all necessary parts and hardware for easy installation. Covered by our Lifetime Limited Warranty.

Perfect! Easy, convenient, definitely recommend
Size: 100LBS, Size: 100LBS
I am so glad I found this base that I can just fill with water. After screwing on the wheels, I used my garden hose to fill it with water and put my 1.5 inch diameter umbrella in and tightened it. Easy peasy. I love that it rolls and I can move it wherever I want, and also lock two of the wheels if needed. Definitely would recommend this one!

Sturdy, well built has wheels that makes it easy to move and also lock in place.
Size: 100LBS
Happy with my purchase. Sturdy well built, love that it has wheels makes it easy to move around and wheels lock in place. I choose to fill it with sand and water as it gets really windy where we live this will prevent my umbrella flying to the neighbors house again 😅

Must Read before Purchasing!!!! Height is lost if you use this base!!!!
Size: 100LBS
I was so very excited about this for our umbrella - and then I put it together.
I called my adult son to come and take a look - I had to be doing something wrong.
To our dismay, I was not.
The lowest pole in the umbrella system has 4 welded pieces with holes meant to connect to the legs, thus stabilizing the structure. The lowest pole measures (guestimate) 3 feet.
When you choose this system, you do not use the original cross-bars, nor the original lowest pole with the 4 welded pieces. Rather, you use a newly provided lowest piece roughly measuring a foot. In doing so, the structure loses a total of almost 2 feet. For average-height individuals, this would not be a problem. For individuals 6' or greater, this is quite a problem. My son is 6'6. My husband is 6'2.
I really wanted the portability of the product. However, we will be returning it for the kind that rest on the cross-bars. I wish someone had mentioned this in the reviews I read and saved me the trouble.

Makes moving your umbrella around a breeze.
Size: 100LBS
This is best idea in umbrella stands. Decent price. I love that the water intake/release is on the side. Many are on top of the stand. Doesn't leak. Easy to move around and easy to put together with the included tools. I have 2. One for a very heavy 10 x 6' umbrella, and the other for a very light 1/2 round umbrella. Works equally well for both. One tricky part the instructions don't include is that is parts F and J are 'in place' in the base and you need to remove them to re attach them to the cylinder, or what they refer to as the "stand pole". So, if you are looking for parts (and I did this twice), just remember you will find them on the underside of large plastic umbrella base. Both are black, and so not immediately apparent. Love that there are two locking wheels and they include an extra screw. IKEA could learn a few things here.
