question after LM installation

just installed a loudmouth on my 02 formula and im getting a light rattle at low RPMs (1200-3000) that sounds like its coming from the rear - and I cant hear it under idle or under cruising. any suggestions?

it also drones a bit in the midrange RPM which I have read is common with this system. any recommendations on replacing the resonator with something that sounds a little better?

mine was rubbing right where it goes over the rear axle just before it splits...look for signs of rubbing....mine wasnt rubbing all the time either...just at certain points in the RPM range.

Mine actually was rubbing on the G-load brace. I bent it down a little and added some rubber padding and it's good to go.

if u wanna replace it, go to LS1sounds.com and listen to borlamouth, dynomouth, or magnamouth...they all have their ups and downs...also look into powersticks or sweet thunders for a deeper more old school tone...
