I was running B-pipe out for a while and after finally getting annoyed with the sonic boom sounding exhaust note, I decided to put back on the rear section of my exhaust. It is now making a pretty irritating sound around 3800rpms. I double checked the bolts to make sure it wasn't rubbing from them being loose and everything is tight.

Is it possible that I blew out the innards of the muffler?

 

check the heatshields. (all 3 towards mid/rear)

 

I removed them all- it's definately the rear section...

I think its either rubbing at the bolts that connect it to the b- pipe or it is the inside of the muffler housing.

If it is the connecting area then are there some rubber washers I can use or???

 

Maybe the exhaust donut is leaking. Clean that area and see if it turns black after a few days of driving.

 

1. check heatshields for cracks and loose bolts
2. check exhaust pipes for cracks/leaks.. anywhere on exhaust pipes you see black spots... same exhaust buildup you see inside exhaust tip - thats where you have a leak..
3. check gaskets for leaks

Try these. Theres nothing in the muffler to actually go bad

 

Is there a gasket/ donut between the rear section and the b-pipe?

 

Just remember that if you replace your muffler with another stock muffler, and you buy it from the dealer and let them do the install, it comes with a lifetime warranty that covers parts AND labor. Something to consider.

 

there should be a dunut gasket since it spring tension bolts, look at connection where pipe connects to muffler, see if theres any black spots around welds
