anybody have the flowmaster super 44,s on thier 5.4? how loud?good and bad comments welcome.thinking of going duals w/44,s.thanks,bill

 

I would suggest a magnaflow, the flowmasters sound good, but are known to cause a loss of hp and tq.

 

not on a 5.4, but I got them on my '05 6.0L Silverado & they sound bad ***, very deep toned low rpm, straight piped sounding WOT

 

yea i have super 44 si/do with 3.5" tips ngled out back. it does have a really nice sound pretty darn deep for just a replacement muffler. i can deal with the supposedly loss in performance i dont notice it that much. a friend at school listened and asked me if it was true duals lol
