Overview:

For the person who wants a subtle custom appearance with all the benefits that a Flowmaster Cat-back exhaust system provides. This American Thunder system for the 2001-2006 (2007 Classic) Chevrolet Silverado, GMC Sierra 2500HD/3500HD with 6.0L or 8.1L engine with dual inlet muffler, delivers a moderate interior tone with a deep powerful exterior tone and is suited to the enthusiast who wants their performance to be heard. The system attaches to the back of the catalytic converter with a dual inlet 50 Series Big Block muffler for a deep powerful sound without being obnoxious. Includes a large custom formed aluminum heat shield with stainless clamps and easily attaches directly to the muffler body. The custom bent 3.50-inch 409 stainless steel tailpipe uses the factory hanger locations for an easy installation and exits out behind the right side rear wheel which is ideal for towing. The tailpipe is finished off with a large 4.00-inch polished 304 stainless steel tip embossed with the Flowmaster logo. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, these systems include all necessary parts, hardware and easy to follow instructions for a trouble free installation. Covered by Flowmaster's Lifetime Limited Warranty.

    fits my Sienna 2006 with a little adjustment - sturdy, clean and happy that I brought it
    Size: 8.3" x 8.4" x 0.6"
    I brought this for my Camry 2006 and I have a Sienna 2004 as well that use the same regular cabin filter with the exact model. But when I put this K&N filter on my Sienna it doesn't fit well. The K&N filter sits in the plastic cabin filter frame exactly but there are four little plastic square on the side of the plastic frame sticking out that were in the way. I trim off the K&N border a bit and also the frame too in order to fit in. Beside a little adjustment, it works perfectly for my Sienna 2004. The smell is gone. I also use an oil pen to note on the K&N filter that "Do not replace" in case the dealer replace it during a maintain. I would buy more but this is life time I will buy another one for my camry. I am more than glad introducing this to my friends

    Make sure it fits your vehicle cabin filter.
    Size: 8.3" x 8.4" x 0.6"
    I like that it last long and I don't need to buy replacement every time a funky smell starts appearing after turning on the car or truck AC or heater. Saves money by easy to maintain without replacements.

    buen material
    Size: 8.3" x 8.4" x 0.6"
    Es una buena compra excelente producto calza perfectamente en mi Fj cruiser 2011, en cuanto a su durabilidad lo diré cuando pueda hacerlo por lo pronto está instalado cuando haga los primeros lavados volveré a comentar si se mantienen en buen estado como promete. Lo que difiere con el original es que un lado va para abajo el que tienen una felpa tipo algodón y el otro para arriba en cambio en este filtro de cabina K&N no se sabe cual lado ba abajo o cual arriba, por eso menos una estrella

    It works as advertised
    Size: 8.3" x 8.4" x 0.6"
    The one thing I haven't found out is if the product will remove exhaust smells - I don't believe it will, but the nice thing is that air flows a little bit better then the Toyota FJ carbon filter that was in there. I don't believe the previous owner even knew it had a cabin filter. Glad to have this in there.
