I would like to get some other opinions on exhaust for the 5.4, I was wondering what setup (mufflers,pipes,cats) would yield the deepest sound and most horsepower

 

Flowmaster 40 and Borla seems popular at this time for 5.4.

I heard that Flowmaster only flow 250 CFM approx... i dont know if its true or not..but it has some good rumble at idle and a bit loud than Borla...

YOMAN!

 

i have a flowmaster on mine and i love it, good deep sound, i got alittle better MPG and felt alittle better performanse

 

Very few muffler guys show their flow rates because they're so low. Look at this chart:
www.dynomax.com/ultrafloss.stm

In this chart, the number on the second row above each muffler is it's flow rate.

For extremely high flow rates, look at the flow rates in this chart; like the #17220 and #17221.

I'm gonna say Magnaflow. They sound great on every Ford product I've heard them on (Cobra's, GT's, Lightning's and a friends Screw). Well made, less expensive than Bassani, and much more of a throatier sound than Borla (which are a bit too quiet on our trucks in my opinion). Check around and see if you know of anyone with Magnaflow's on their Ford truck. You'll see what I mean.

 

at a missour chapter f150 meet i heard a guys truck that had magnaflow hi flo cats and magnaflow mufflers (dont know which ones), but it sounded pretty dam deep and had a NICE rumble

 

AMEN

I wouldnt trade my Magnaflow setup for anything out there (Bassani, Borla, Gibson, etc)

 

Great info! Wonder how well Magnaflow does...

In sound loudness an quality of sound, is Magnaflow or Dynamax or the Bullet resonators louder???? Thanks!

The Dynomax Race Bullet would be the loudest... its basically glasspack w/o louvers to disrupt the flow. I had one on my truck and it was LOUD! I had a Dynomax Ultraflow on my truck (Oval w/14" case) for a little while and it had a deep mellow tone but it wasn't very loud.

 

I have the Bullet on my truck. Its a little bit louder than the SIDO flowmaster that I used to have but I think it sounds good. You cant beat the price for a Bullet

 

Magnaflow sounds great, looks great, and last:

Is the Bullet exhaust made by Dynomax? The guy at ORW was talking about Bullet exhaust. Wasnt sure.

 

Its a muffler made by Dynomax. Mine is just a single 3" turned down in front of the axle.

On my 2001 supercrew I went with the dual set from Summit racing Sounds good and the dual setup looks good.
