This Flowmaster® Outlaw® cat-back exhaust system is for the 2021-2026 Ford F-150 trucks with the 2.7L, 3.5L and 5.0L engines and offers maximum sound levels both inside and outside of the truck, with all of the performance benefits that you would expect from Flowmaster.

    Good Product, But Doesn't Fit All RAV4 Models
    Size: For Avalon 19-22|Camry 18-24|19-25 RAV4/ES350, Size: For Avalon 19-22|Camry 18-24|19-25 RAV4/ES350
    Both filters seemed to be of high quality, but the engine air filter did not fit in my 2019 RAV4 XSE Hybrid. Please note that ordering this was my mistake -- I didn't realize that the hybrid and gas-only filters were different sizes -- and that StaunchAuto also offers a hybrid version of the kit, which I have just ordered.

    Exactly as pictured
    I ordered this air filter for my car, it is exactly as described and pictured. The fit was perfect and the quality is worth the price.

    Great filters at half the price of others. Try them! They are just as good as the pricier ones..

    Don’t pay the labor fee. Do it yourself
    Much cheaper than having the dealer install it or even from the auto parts store. Easy to install, took less than 5 minutes.
