I'm looking to buy an 2004-2006 F150 (4.6 or 5.4) and am wondering how loud a magnalfow 14" round body muffler would be. Any idea what Flowmaster model it sounds like? I want it aggressive and deep, but not obnoxious. And I would like to hear it a bit in the cab. Just want to know how this muffler would be based off of what I'm looking for.

 

SI/DO btw

 

Magnaflow round body mufflers are SI/SO only. If you want a Dual Out you will need to look at the Oval bodies.

The 14" round sounds similar to a 40 series Delta once broken in.

 

What he said.

 

Thanks guys... I meant oval body... my bad. Is the sound similar even with the oval body to the 40 series delta flow?
