Subaru WRX STI Forester XT EJ20 and EJ25 2008 to 2021 Downpipe kit - ES-SW08-KITB

Unlock the maximum potential of your turbocharged Boxer engine with the Xforce 3" Downpipe Kit. Specifically designed for EJ20 and EJ25 platforms, this kit replaces the highly restrictive factory downpipe to significantly reduce backpressure at the turbocharger. Featuring a high-quality cast bell-mouth dump pipe, it allows exhaust gases to exit the turbine wheel and wastegate more efficiently, resulting in faster turbo spool, increased horsepower, and improved throttle response.

Note: This downpipe is specifically designed to bolt up ONLY to an Xforce cat-back exhaust system. Engine ECU tuning is mandatory after installation to optimize performance and ensure engine safety.

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.

⭐️⭐️⭐️⭐️⭐️ Easy to use and produces vibrant prints
This Hiipoo sublimation ink has been a fantastic upgrade for my EcoTank printer. The autofill bottles fit perfectly into the ink tanks - no syringes, no mess, and no wasted ink. Refilling is quick and hassle-free, which makes the whole process so much easier. The print quality is excellent. Colors come out bright, vivid, and crisp with great saturation and no fading. It transfers beautifully onto mugs, T-shirts, and tumblers, drying fast without smudges. I really appreciate that it works ICC-free, yet still delivers professional results. The ink is certified and feels reliable, and I’ve had zero clogging issues. Overall, this is a high-quality, easy-to-use sublimation ink that’s perfect for both hobby projects and small business use. Definitely recommend for anyone doing heat transfer printing.
