6mt only i guess, does anybody get a loud farting noise , not a pop, in the exhaust when they let off the accelerator pedal in high rpms in 2nd or 3rd, it happens to me from time to time, it lasts for a couple of seconds the car sounds stupid and it feels like it shakes inside, is this due to the exhaust valve or something, can't figure it out.

 

If its a pop under load in higher rpms its probably a back fire. My 300zx used to do it all the time when I let off around 4k due to the tuning and exhaust setup.

 

haha , he said "fart"

 

it could be the trunk monkey

Just feed him more fiber

 

backfire.....????
