Hi, I am new to this site. I just bought an 02 F150 4x4. It has the 4.6 V8. I had the muffler cut off and the exhaust straight piped with true duals. it is a little to raspy at high rpms. I am looking for a muffler that will keep the deep tone and not make it too much quieter. I just want to get rid of the raspy sound at higher rpms. does anyone have any sound clips of their 4.6 with custom exhaust such as magnaflow, flowmaster, etc? or any suggestions. thank you very much

 

summit.com fordracing.com dynomax is a good muffler... you dont want any slowmasters magnaflow is good..

 

Dynomax Ultraflow is a nice muffler. I have one installed siso with stock 2.5'' pipe and it sounds nice. One of my friends has them true dual with 2.5'' pipe and 4'' tips and it sounds wicked!! Nice mellow rumble at idle and when cruising, but when you step on it all hell breaks loose.

 

i think im debating between the flowmaster 40 series or super 40. what is the main difference. which would sound better on my 4.6? i am looking for a deep tone and nice rumble. does anyone have any sound clips of their 4.6 with the flowaster 40 or super 40? thanks

 

yes, Flowmaster

the origional 40 is deoop loud & can pop, Super 40 is what you really want, hardly any pop, deep & mean.

 

Ive got a dynomax bullet. Its really cheap cost, and is a great sounding alternative, to your super expensive flomaster/magnaflow etc.
