It's not always noticable. Mine is most noticable on highway on/off ramps (turning right). Check the knuckle joint in your driveshaft after like a week of driving. If its rubbing you'l see a ring where the paint wore off on the joint.

 

alright thanks, ill have to check when i do my oil change

 

If it is rubbing you will be able to hear it not to mention see where the knuckle is actually machining away material on the resonator.

 

I noticed mine when it would rain. I believe the rain would cause the exhaust to contract and push into the pilot shaft joint. If it is rubbing it will sound like a Whining/grinding sound.

 

i have an 8 but i had no problems with rubbing or anything, not sure what the problem is.. my exhaust mated with a helix dp and hfc.

 

Problem fixed. (resonator delete)

 

My cousin has a 9 mr and had the same problem. WHat he did was buy the Kartboy hangers. It helped a little but the huge resonator was still in the way. All he did was go to an exhaust shop and have the resonator taken out and replaced with a straight 3 inch pipe. It sounded noticably deeper. This was the only way my cousin solved this problem you have. -Johncy
