Ive had my GMPP SPORT CATBACK EXHAUST on for a month or so now and whenever i start off and dont give it a good amount of rpms, or sometimes when im cruisin in higher rpms, i notice my exhaust rattling what feels like right under my feet, is the exhaust known to rattle in some places, and is there a way i can fix it, its slightly annoying lol...thanks

 

check your hanger,mine came off the hanger in the same spot and had a rattle or you have the hanger turned upwards causeing the exaust to rattle off the shield

 

how would i be able to tell, i used the stock hangers... do you think i put them on wrong??

 

i doubt you put them on wrong. its just when you put the exhausts on in pieces how close you line up everything to the body. just take some pliers after you jack the car up properly and bend some of the shield away from the exhaust and after that there should be no rattle.
