    Aggressive Sound. The stock exhaust doesn’t really match the beast of an engine your Mustang has. The SLP Loudmouth Axle-Back Exhaust eliminates the restrictive factory mufflers to produce the loudest, most aggressive rumble as soon as you start the engine. The design effectively reduces the back pressure for enhanced efficiency and power with a loud turbo hum that grabs attention right away, even in the noisiest street.

    Durable construction. SLP Loudmouth Axle-Back Exhaust is engineered from 2.5” high-quality 409 stainless steel tubing for excellent corrosion resistance and added toughness while pre-welded hangers ensure easy installation without hassle. The tubing is mandrel bend to provide an unrestricted flow that helps spike the power of your baby. Hand-polished 3.5" stainless steel tips provide a bright finish that adds a rich look to the rear of Mustang. This makes sure you get the evergreen blend of style and quality even after years of rough usage and aggressive drives.

    Emission Legal. This SLP Exhaust is CARB certified and is smog legal among 50 states so you can enjoy the ride without worrying about breaking the law.

    Clamp Installation. Made for easy installation, the SLP Exhaust comes as a direct bolt-on replacement without the need for any kind of modification so you can easily swap them with your factory exhausts with ease.

    Limited Warranty. The SLP Loudmouth Axle-Back Exhaust comes with a limited warranty that covers all defects in craftsmanship and materials. For more details and possible exclusions, check the manufacturer’s site.

    Application. The SLP Loudmouth Axle-Back Exhaust is made to fit any 2005-2010 Mustang GT and GT500 Models.

      SLP Muffler Delete

      So let me just start off with saying I bought these because they were supposed to have 5 inch tips, upon receiving them I realized they're still 3.5 inch tips so just be warned. I contacted American Muscle and spoke to Joseph who was very apologetic and even sent me a free T-Shirt for the trouble! I did not want to send them back because they are beautifully designed and sound amazing. Overall it's just a muffler delete but I give a solid 9/10 for fit, finish and sound.
