ATP Turbo 3" Stainless Steel Downpipe with 4.21" Marmon Flange for Borg Warner S Turbos
$39.00

If you're diving into the world of turbo setups, you know how crucial the right downpipe flange is. This 3" Stainless Downpipe Flange and Clamp is a solid choice for anyone running Borg Warner S, SX, or SX-E turbos—think S200, S300, S200SX, and S300SXE, just to name a few. Trust me, this isn't just another piece of metal; it’s crafted from 304 Grade stainless steel, machined from billet, which means it’s built to last and resist corrosion like a champ.

One of the standout features here is the 4.21" outer diameter with a contoured, beveled face that’s specifically designed for those Borg Warner models. This isn't some generic fit; it’s made to match the unique characteristics of those turbo series. When you slip a 3" OD tube into the back end, it’s ready for welding—simple as that. And if you’re looking to upsize to a 3.5" downpipe, you can easily grind down the tapered section on the flange. It’s versatile and gives you options, which is always a plus.

Oh, and let’s not forget about the V-band clamp that comes with it. It’s made from high-quality stainless steel right here in the USA, so you know you’re getting something sturdy. No flimsy parts that’ll let you down when you’re pushing your setup to the limit. This clamp holds everything tight, ensuring a leak-free connection that keeps your performance on point.

Whether you’re building a street monster or a track-ready beast, this flange and clamp combo is a reliable choice that won’t let you down. You’ll appreciate the craftsmanship and the thought that went into making it. So, if you’re ready to step up your turbo game, this is a piece you’ll want in your toolkit.
