exhaust only comes out of one of the pipes coming out of the muffler. This is wierd. I picked up a 2004 G35 sedan last week and i swear it was coming out of both pipes, but not now.
anyone else experience this?

 

huh? what do u mean it only came out of one of the pipes? sedans dont have dual exhaust

 

two pipes off same muffler on sedan, only one has air moving out of it from what i can feel and see

 

thats weird, i dont have my stock exhaust anymore but i kno when i did mine didnt do that? i dunno y yours would

 

Infiniti designed it that way. At low idle, only one of the tail pipes is open.
At higher RPMs, both open up for more power. Infiniti states this on their web site.
I upgraded to the HKS rear section exhaust, both pipes are open all the
time.
