Hey guys. Ill get straight to the point as i've been looking through other threads like this but do not find the simliar problems...
It kills me everytime i get in the car and have someone setting with me there is seems to be like a plastic on plastic noise coming from their seat, but the seat is moved forward and not leaned back. I have observed for a little while and think it may be the seatbelt on the leather, because i tested it on mine an it sounds familiar but not as loud and doesn't happen when i sit. It happens even when the passenger doesn't move...

Im not to concerned about this as i am with the seat...
but, when i have the top up (sometimes this happens sometimes its doesnt) there a realllly weird sound which i know people have heard similiar before but its a very strong vibrating noise at about 3k-3.8k and around idle as well... its coming from the back it seems like... If you have any idea please let me know. Im not to concerned about this as i am with the seats...

FAQ

 

Do you have an aftermarket high flow cat or tp?

if so it could be resonating / vibrating on the underbody?

 

Yea...i have a high flow signle exhaust.
and btw Ckit, i see you always going to people's threads and going FAQ, well i went to the FAQ and i cannot find it so maybe you can please post FAQ with a link behind it sending us there instead of just saying, FAQ because like i said in my description i have looked through forums.

 

Spare nut?

 

I bumped my exhaust, and there's a MINOR crease on the bend which forced the cat over to the right. At 3k-4k where's the most resonance I have the same symptoms you described because it's vibrating against the underbody.

While I can't say you have the same issue, my symptoms are very similar and that's the cause.

 

hey dude....i found this https://www.s2ki.com/forums/index.php?showt...&#entry18033716 (not in FAQ in don't think; unsure)......is this helpful?

good luck!

 

i guess i dont notice it over my exhaust. lol
