Anyone run a 4.7 w/o mufflers?
 
I am looking to liven up my exhaust note, and im thinking of going with magna flow exhaust. From what i have found on youtube, it sounds great.

My quetion stems from a friend, who owns a 2008 Ram w/5.7. He went to the muffler shop to get something louder put on, but he asked them to remove the mufflers then fire it up to here how it was. When they fired it up, it was only slightly louder than with the mufflers on...weird, yes. Is that how the 4.7 in our WK's is? Anyone have some experience they want to throw in here?

Oh and hello, first serious post on JG.

I have an SRT exhaust on my 4.7 without the muffler and the sound is awesome IMO. It does have the SRT rear resonators as well. I would post a new clip...but my 4.7 is highly modified and wouldnt give you a good comparison as to a stock 4.7.

Spill the beans on the mods, im interested :)

Thanks also for the mini review. Its almost paid off and ive been driving it around for 3.5 years stock :(

Im starting to see more of the WK's and its really bugging me that its stock....lol.

You are in the right place to mod then. The mods for the WK are almost endless....for performance and visual.


I replaced my 06 4.7 with an 08 4.7 stroked to 5.7, forged, cammed, race ported heads etc. I am now working on tranny upgrades. The visuals are obvious by the sig pic or just search my username.

Im sure its been covered, but why go to a stroker 4.7 instead of a 5.7 or 6.1?

And congrats on owning a wicked ride lol.

theres an exhaust clip thread here too with lots of clips and videos

Found the exhaust clip thread. As much as i hate to say it, i like how the flow master 40's sound on the 4.7

I had a 5.0 mustang, and the magnaflows made it sound awesome...but the 4.7 loses that awesome smooth sound the 5.0 had. Unless im wrong, anyone here have a better quality clip of magnas on a 4.7/5.7?
