Hi, i have a 03 f-250 and i just put a flowmaster super 40 muffler on my truck and it sounds stock. why? I just removed the stock muffler and replaced it with the flowmaster. I thought the super 40 was one of flowmasters louder mufflers? Should i replace it with something else? Please let me know what you guys think. Thanks

 

i have a 50 series on mine...same as you just replaced the muffler and my truck is much louder

 

on my 02 f-250 with the 5.4 i put a 2 1/2 cherrybomb glasspack has a nice rumble not too loud

 

Thanks for the reply but doesnt glasspacks have a "crackle" sound? Im not looking for that sound I would like the deep rummble. I was thinking about putting the flowmaster super 10 or magnaflow bullet. Has anyone tryed these? If so let me know what you think.

 

I find it hard to believe that it is not louder than stock. Maybe it's just not as loud as you expected it to be?

I installed a Magnaflow single in/out in place of the stock muffler and although it's not considerably louder it has a nice tone to it. I had researched the Flowmaster 40 series through several peoples experience and had the impression the Flowmaster was louder than the Magnaflow. Just my .02 cents

 

my glasspack dosent crackle all i hear is a loud boom boom the reason why they crackle thin small pipes from what i have seen/hear but if you just cuting the muffler out and using the stock 3" pipe has a nice rumble

 

If your truck still has the stock cats, they are excellent mufflers.

 

do you have a psd or gas on my 00 psd its straight pipe and sounds great

 

Thanks for all the replys. It help.
