Rattle from break light behind rear windshield!
 

I have an aftermarket exhaust and test pipe so when im going from 1-3k rpms i get a raddle from the break light. Has anyone else got this issue? Please help if you have fixed this issue!

The back dash area is the noisiest/rattle prone part of this car as you add exhaust or stereo equipment... A combination of sound deadening dynamat behind the pillars, the deck, the keyfob sensor, the plastic molding of the brake light, the plastic molding pieces that surround the opening (window insulation strip foam used) should help.. If not dynamat the trunk and trunk lid. Lots of work, but it all adds up to a quieter car with little weight added.

Old thread...... But I'm on the same boat! Going try the dynamat in a couple weeks. Hopefully not too costly?
