SLP Loudmouth II Dual Side Exit Exhaust (04-08 4.6/5.4 L F150 SuperCab 6.5ft bed / SuperCrew 5.5ft bed

Muscle-Car Inspired Style. For years, the name SLP has been connected with the biggest, baddest aftermarket performance parts for muscle cars. Now you can have their same signature sound and power for your F150. With their all-new side exit Loudmouth II cat-back system for your 04-08 F150, you'll get a big, bold sound with a sporty dual side exit look.

Signature Loudmouth™ Sound. The aggressive muscle-car tone of this exhaust is achieved by using a pair of stainless steel Loud Mouth II resonators. Combined with the more freely flowing design and attractive 3.5" dual-wall stainless steel tips that emerge from the passenger side of your truck, this exhaust is sure to impress both your buddies with its power and your date with its big, deep sound. The modular design also allows you to moderate the exhaust's tone by stepping up to an even bigger sound by installing a pair of bolt-in original Loud Mouth bullet-style resonators, which will make even the concrete tremble in fear with its truly loud bass rumble.

Bolt on HP, TQ. The Loudmouth II doesn't offer just exceptional sound and style - this system adds up to 10 HP and 10 lb-ft of TQ as well.

SLP Quality Construction. This top of the line exhaust is hand-crafted from 2.5" stainless steel, and features rotating dual side-exit 3.5" polished dual-wall stainless steel tips for a show-quality finish.

Lifetime Warranty. SLP is so confident that this system is designed to the highest standards, they back it with their limited lifetime warranty.
