Just put a set of 4" Rineharts on. With out taking the baffle out to look i was wondering if they wrap them with packing. Im guessing not. Got 500 mi on since i installed them and seem like they may be getting a little louder which is fine with me. Maybe i just think they are getting louder. Thanks

 

mine did not have any

 

Generally wrapped mufflers get louder with miles and then level out. If not wrapped I would think the sound level would not change.

 

Thx guys. I know there not getting louder, just in my head. They sound good. Again thx
