This is the second f 150 I have installed the super 40 muffler on. Both have a deep tone and sound good.

Had bad factory cats so I redid my entire exhaust. Flowmaster cats seem to be working just fine. Service engine light is off. Definitely have more power and torque. And not sucking down a ton of gas!!!!
