I am looking to put a Flowmaster muffler on my 199 Ford F250 v10 Super Duty, wondering which model would give me the loudest and most aggressive sound? Any suggestions would be appreciated.

 

There's a v10 excursion on youtube with a super 44 muffler that sounds pretty good here's a link to it Some people also like the areo turbine 3030 muffler if you want the loudest you can just straight pipe it but it will sound like crap.

 

In my opinion the , flowmasters sound like crap on a v10 .
I went with a magna flow .
Single in, double out.
Sounds much better , and no drone .

 

Skip the flowmaster. Magnaflow, Jones or Dynomax Super Turbos are what I would use. My 99 had a Borla system, 05 a Dynomax #17792 and now my 02 is getting a Jones max flow(Magnaflow copy).

 

I have a Dynomax ultraflow bullet on my V8, and it is very loud.

 

Race Bullets are loud, that's for sure.

 

I had a single in dual out Magnaflow on my V10 3V and didn't like the sound at all. I ended up using a flowmaster BB70 single in dual out and was much happier with the sound.

 

And I love it. Race bullet with exit right out the side with a dynomax 4" tip.

 

Nice!
