Just put on Slp Loudmouths, they sound great but I have a vibration/rattle during certain low rpm idles that won't go away...I used the provided clamps to install, Would it help to weld them on? Anybody have this happen to them? Solution?

Also check the hanging brackets, mine was hitting on the rear bracket on axil.
