Hello lude crew i think i got a prob with my 5 th gen lude it has muffler, headers and intake, whenever i am driving and i de accelerate/ let my foot off the gas i hear a low pitch fluttering noise from the exhaust, is this normal?? it lasts a least a second. any ideals ?

 

mine does the same since gutting my cat...i'd say it's pressure-related

 

is it like a really quick little "pff" noise?

my sisters boyfriends G35 coupe has an exhaust leak and it sounds sort of fluttery

 

coming from your exhaust? or like.. underneath or car? or from the header?

 

sounds like it coming from exhaust, like kinda sputters makes a sound when i let go of gas on all gears.

 

normal. this happens on my car and every other lude i've been in.
