My 2012 is getting quiter. Engine idle and exhaust

 

wow,wierd,i've never heard that before

 

How do u figure that out? Im not doubting i just wanna know how yer telling the difference?

 

are your RPM lower

 

you forgot to pull your ear plugs out after work man just had to be a smart a$$ a little bit

 

Have you used any fuel additive(s) lately? Maybe your kitty is clogging up (assuming you still have it). OR, excessive ear wax build up....
Are ya running 5" straight or muffled? Maybe an issue with the muffler (assuming youre running one)

 

No muffler straight piped 5 inch

I might just have gotten used to the noise

 

5" straight piped and getting quiet

 

Well thats defenelty not the case with my 5" straight exhaust!

 

Very well could be.
I bet that sounds freaking awesome!
Have you noticed your truck running any different?
