How many resonators are on the 4.7l and where are they located? im running a flowmaster 40 in place of the stock muffler and was thinking if i removed the resonators it would give me a little different sound and also read it would cut down on some drone

 

Im not sure on the 4.7 I wanna know also

 

im reading about the bubble in the exhaust pipe being a resonator so i was wondering if there was more than one

 

What is this bubble you write of? I have no resonators and still have 8yr old stock exhaust.

 

ok im dedicated its 20 degrees and snow on the ground but i went out there and snapped some pictures

bubble from wheel well:


bubble from underneath looking foward:


flowmaster 40 muffler:


stock y pipe (look how crimped it is):


stock cats:



as far as i can see there is only the bubble for a resonator but that stock y pipe is ridiculous

 

You know, I'm gonna have to go check mine out this afternoon. While doing the timing cover replacement, don't ask, I did happen to notice the y-pipe looking quite crimped.

Very dedicated there Razor, thanks for the pics. BTW it's sunny and 70f here in Phoenix

 

It's interesting to me that someone would suggest REMOVING the resonators to cut down on droning, since cutting down the drone is the only reason for installing the resonators.

 

Side question, anyone ever cut the resonators open? Are there anything in them like the cats?

 

from what ive found a resonator basically attempts to break up the sound of each combustion into more of a hum leading me to believe it would cause drone

weed i have no idea im not wanting to chop it right off because im going to use the stock pipe for my exhaust setup since its already mandrel bent im guessing it looks like a glasspack minus the fiberglass

so my exhaust set up would be cats new y pipe flowmaster 40 remove rear resonator and then a nice rolled tip

 

Come on, mien are already gone (long time ago) so you can be our guinea pig.
