Default Exhaust Spacers

Just had a set of exhaust spacers installed on my JKU and i hear a rattle in my exhaust sometimes when I hit a rough road. Crawled underneath and looked around but no visual signs of where it's coming from.

I will crawl under again tomorrow and check all the bolts but any idea where it's coming from?

Mine too. I think mine is from the exhaust "buzzing" against the crossmember when the engine twists on the motor mounts. It only does it for. Split second under hard acceleration from a dead stop. I put a washer between the crossmember and it lessened it a bunch, but I think I need to add one more to get total clearance.

That's what I was thinking. It is super close to the crossmember. Could you take a picture of what you've done with the washer?

Nevermind... I get what you've done. I'll try doing the same thing tomorrow but maybe I'll throw two in there. Thanks

I put 4 spacers in at the crossmember and the rattle is gone. Thanks for the idea.
