Flo - Pro Exhausts are designed to fit all wheelbase and cab configurations, unless stated otherwise. The kit replaces your restrictive OE downpipe with 4' high - flow piping. You can easily install it on your existing turbo and exhaust system using basic hand - tools. Key features include a 4' downpipe, increased power, better fuel mileage, options of aluminized or stainless steel, and it fits your OEM turbo and exhaust. Note that this kit only fits Ford F - Series Powerstrokes with an automatic transmission.

Using this downpipe kit is straightforward. First, gather basic hand - tools. Then, remove the restrictive OE downpipe from your 2008 - 2010 Ford F - Series with a 6.4L Powerstroke and automatic transmission. Next, bolt the 4' high - flow piping from the FLO 846 kit directly to your existing turbo and exhaust system. As for maintenance, regularly check the connections to ensure they're tight. If you chose the aluminized option, be aware that it may rust over time, so keep an eye on it. For the stainless steel option, it's more corrosion - resistant. Also, remember that this kit is only for Ford F - Series Powerstrokes with an automatic transmission, so don't try to use it on other models.
