Hey everyone. Looking into getting the Flowmaster american thunder for my 2006 f150 fx4. Just wondering if anyone has it and what they think about it. Also, if you've installed it, how was that experience.

Thanks

 

flowmasters are just noise makers. they are one of the worst flowing muflers you can buy.

 

I've had flowmaster mufflers before just not a cat back system and I liked them.
