i was cruzin tonight
and i pulled into a parking lot and i notciced a wierd sound that wasnt there before. When ever my car was revving it made a wierd rattling sound under the car
it seems to drop revs a little quicker than usual also.
it made the sound more when the revs were dropping also
i just wanted the expert opinion of this forum
i think its something exhaust related but i could be wrong
thanks for the help in advance

Check the heat shield where the mufflers flange to the y pipe. That’s where mine rattles.

i dont think that would effect the revs dropping
it just drops faster than usual
im thinking some sort of backpressure loss

maybe you've got a hole somewhere in your catback area.

would that account for the rattling tho??

I have a similar problem. When at idle, I can hear my exhaust pop every 3 seconds or so very softly, and the dealership says that I definitely have exhaust leaks.

it was dark out when it happened
so im gonna take a look under the car tomorrow and see if i could possibly fix it

could it be your cat?

is it possible to remove all the heatshields from the y-pipe without destroying the y-pipe?
