I have a vibration sound when i first take off in my jeep pulling out of drive then at idle it is not there or any other time driving it seems like mostly after first take off after sitting. But then it may do it other times when accelerating from a stop. But not all the time i am assuming something is vibrating against frame or muffler pipes but i have been under there a lot and can't find loose skids heat shields or anything. What else could it be?

i will look at this in the morning dark out now but i will go out put in drive with brake and see if i can get that sound to come back...

I had a similar issue after having my headers installed. It was the heat shield on the passenger side around the location of the catalytic converter.

Holy shit that is EXACTLY the same vibration that I get and under the very same circumstances. Gonna maybe poke around under there tomorrow a bit.

They were expensive but i love em. I have a Tereflex long arm lift so we had to tweak them a bit to get passed the relocated control arm brackets. Sounds good for a V6. Especially at WOT. You can definitely notice a difference and i have not even installed the tune with the Diablo yet. Eventually i will get it dyno'd to find out my true gains.

This happened to me, it was the muffler.

Same here. Gonna see if Jae from CT can help me sort it out.

For my rig, he tentatively diagnosed it as exhaust vibrating against my Skid Row plate due to small tolerance. Think I need shim(s) to increase gap slightly.

Thanks again Jae for helping with this.

Cool but what is the other wrapped piece for Ludski?
