My Motordyne Exhaust has been making a weird noise i think its coming from the ART test pipes. It sounds like something is either loose or stuck in the exhaust.

The Sound sounds like a flapping piece of paper in the wind it makes the exhaust sounds cheap and ricer. Its more apparent when car is in sports mode and you downshift

Anyone have issues with their exhaust? Any input please

 

do you get that sound on acceleration or when you release the pedal?

 

Both, its more apparent in sports mode going from 1st to 2nd and then the backfire from the art pipes you hear that sound but i can notice its not the exhaust tone for the motordyne something is wrong with it. im going to try and raise the car later and check underneath.

 

Air in air out, you may not understand why I'm asking this question..."Are you sure the drop in filter is clean? I had strange noised coming from my exhaust only to find out my intake had blockage causing the issue. Back firing isn't a good thing, are you throwing any error codes?...Gary

 

I have the Drop in Filter and Ztube,

 

No error codes

 

figured out the problem gasket I believe is loose a lot of air coming out when revving the engine from the art test pipes to the y pipe
