    Description

    New Sound Levels. Take your truck's sound to an all-new aggressive level when driving around wtih this SLP Loudmouth II cat-back exhaust kit. It features wide tubes that are split into dual pipes at the end with wide 3.5" tips for the most aggressive sound possible. When you use this exhaust setup you'll enjoy deeper tones and louder notes when driving around.

    Serious Power Boost. When you rely on this kit you don't just change the sound of your truck, you can also add more power to it. That's right, when you add this SLP Loudmouth II cat-back exhaust you can bump the power levels by as much as 10 HP. That's not huge, but this exhaust setup makes your system more efficient and lets your engine run the way that it should. That's a huge benefit.

    Long Term Durability. Unlike some of the kits sold on the market today made from coated steel, this one is made from full stainless steel. The pipes, and the muffler and tip are all made from top-grade T-409 stainless steel. That material is rated to last for years without rusting or corroding. You can use your truck in snowy and icy areas and still enjoy reliable exhaust pipes and a muffler.

    Installs Quick. With this kit you shouldn't spend any more than 2 hours putting it into position. At the most you would have to take an additional hour if you aren't familiar with the system. The kit locks onto the existing mounts and all the hardware is included. If you really aren't sure what to do you could pay a professional as well.

    Application. This SLP Loudmouth II Dual Side Exit Cat-Back Exhaust System is designed to fit 2004 to 2008 5.4L F-150s with the following cab and bed sizes.
