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.

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.

Works
Size: 8.5"x11"
Works great for sublimation. Get plenty of sheets. Great value for the price. The paper is pretty thick and seems to hold a good amount of ink without smearing.

My go-to sublimation paper for crafting
Size: 8.5"x11"
I've used several sublimation papers, and this one has worked really well for my crafting projects. The colors transfer bright and vibrant, and the images come out crisp with good detail when using the proper sublimation printer and ink. The paper feeds smoothly through my printer and feels like a good quality weight—not too thin and not overly thick. I've used it for tumblers, keychains, and other sublimation projects, and I've been happy with the results. I also appreciate getting 110 sheets in one pack because it lasts a while, especially when working on multiple projects at once. Overall, this is a reliable sublimation paper that gives consistent results and is great for crafters or small business owners.

My Go-To Sublimation Paper — Flawless Results Every Time
Size: 8.5"x11", Size: 8.5"x11"
This is hands down the best sublimation paper I’ve used and the only one I continue to buy. I get a perfect transfer every single time—no fracturing, no fading, and no uneven results. The paper dries fast, which makes my workflow so much smoother, especially when I’m producing items in batches.
I use this regularly to make air fresheners and tote bags for my small business, and the color payoff is always vibrant and crisp. The transfer rate is excellent, and it works beautifully on light-colored, high-quality polyester and other sublimation-ready surfaces.
If you’re a small business owner or crafter who values consistency, quality, and ease of use, this paper is absolutely worth it. I highly recommend it and will continue to repurchase.

Best Sublimation Paper
Size: 8.5"x11"
I’ve been using A-Sub paper for my sublimation projects, and it is easily one of the best. The ink dries almost instantly once printed, so I don’t have to worry about smudging the design or getting those annoying "pizza wheel" marks from the printer rollers. The paper itself feels substantial and doesn't tear or curl easily. One of the biggest wins for me is that it never jams; it feeds through perfectly every time, saving me the frustration of wasting expensive ink and paper.
When I go to press my designs, the ink releases almost completely, leaving very little behind on the paper and putting all that color onto the project. The final results look super professional, with colors that are vibrant and sharp rather than looking faded or dull. It has worked perfectly for everything I’ve tried so far, and if you want a reliable paper that gives you consistent, high-quality results, this is definitely the one to get.
