i'm a huge flowmaster fan and would like to put one on my 02 F150 with the 5.4L. i used to have a 4.0L ranger with a 40 series flowmaster (chosen because it is the loudest series) on it and it sounded great but i'm worried that if i put a 40 series on a 5.4L it will crack (my brother put a 40 series on his 4.3L sonoma with duals and it cracks pretty badly), which i want to avoid at all costs. there is a 50 series that is slightly quieter than the 40 series and seems more suited for larger displacement engines. any input would be appreciated, past experience, tech articles read, etc. thanks.

yes those are the links i fixed um thanks for letting me know

 

NP, second clip sounded real nice

 

that does sound great, you said that it is a Super 40 Series? i know this is being nit-picky but do you happen to remember how high your RPMs were when you revved it in the video? i only ask because sometimes an exhaust won't crack unless it's at a fairly high RPM. also what diameter tailpipes did you use? thanks.

hey i think i revved the rpms pretty high when i shot the clip. it is 2.5 inch pipes and the inlet on the muffler is 3 inch and the outlets are 2.5 inch i used an upsize to make the muffler work. all 2.5 inch piping

 

u can hear it, but its not deffening loud

 

Ok Im wanting something a little louder, but not so loud that I see red and blue lights in my truck everytime I look in the rearview, would a flowmaster 40 be good for this, or should I go with something else, it sounds really good, but its hard to tell how loud something is just by a vid clip. Thanks

 

I have the Flowmaster 40, SIDO and I don't consider it loud at all. It has a nice throaty sound and you hear it on acceleration, but not real loud.

 

Sweet thanks bluejay

both vids are with the flowmaster equiped and windows down.

 

Thanks. I'm leaning towards going with the 3 inch SI/SO muffler with a single 3 inch tailpipe that exits at the stock position except it will exit at a 45 degree angle instead of the factory 90 degrees.
