Hey guys Yeah i know i know give my exhaust a rest! BUT I CANT HELP IT!! But Here is just a question for you guys. I was on youtube and i saw a video of a 4.7l durango like mine with no muffler. The guy was probably changing mufflers and decided to make a vdeo. But my question is when istraight pipe my durango 4.7l and ran tail pipe why does it sound different from what his sounded like?

Mine is a 2002 4.7L V8 dodge durango and his is a 2003 4.7L dodge durango


Heres my video:

Here is a 5.2l Durango with no muffler i thought i'd throw it in for comparison:

Does it make a difference just leaving it open under the cab vs having full pipe afterwards???

I'M REALLY CURIOUS ABOUT HOW WHY THIS IS GUYS!! PLZ AND THANKS IN ADVANCE!!

AND "45AUTOPETE" IF YOUR READING THIS DONT GET MAD I DONT PLAN ON DOING ANYTHING JUST LOOKING TO LEARN SOMETHING!!!!!

 

Open under the cab will be noisy inside the cab vs. pipe out the back end. Also in stop and go driving with the windows down the exhasut fumes will enter the vehicle much easier.

 

I have my muffler off also!!!!!!!!!!!!!!!!!!!!

Well do oyu still have stock piping? 2.25 inch piping? and do you have it dumped after the muffler or do do you have a full tail pipe afterwards? Which video above can you compare it too lol?
