FlowMaster Catback Exhaust

[Cobra18]

Does anyone use a flowmaster catback on their 5.0? How do the "American Thunder" and the "Force II" Flowmaster Catbacks sound with the stock pipe/headers? What catbacks would you recomend under $300 dollars?

just call summit racing and order two dynomax bullet race mufflers take them to ur local shop and get them welded up. you will have an awesome soundin car

I'm also going for some performance, not just sound.

My car came with the flowmaster catback with Lx tips it sounded great.....before I tore the car apart.....they are in the trunk now....but it had a catted H and l/t headers so it may sound different than yours.

american thunder is the classic 2 chamber catback, force mufflers are 3 chamber. American thunder sounds better
