alrite for the past week theres been a rattle i cant find where its coming from this time..now those of u that have the 70mm knows how loud it is..the rattle doesnt occur all the time only between 2.5 and 4k rpms..this is where the exhaust system vibrates the car the most in acceleration..i only hear the rattle during this point and sense i cant pin point it inside around the consol area im guessing its outside and might have something to do with the catback..i havnt gotten under to take a look at it yet but i will after work 2mrw..its kinda faint so im guessing its prly loud outside and i just cant hear it inside as bad but its still hella loud enough to hear over the exhaust system so it has to me somewhat loud..anyone have any ideas of what it could be hitting? BTW ive had the exhaust on for about..~3-4 months but i never got back under it to tighten anything up like i was supposed to..oh yea and the hangers have been cut so its not a muffler hanger issue..could it have to due with something somewhere around the header/cat. and catback connecters since it sounds like its coming from the middle of the car around the consol area? like the header springs (if any on stock header i forget..)? hanger issues other than the muffler hangers (which i had cut before the install)?
