Hi,

I drive a 2005 g35 coupe 6 MT completely stock and around November last year i noticed the exhaust backfiring but not too loud it was very subtle. It was around the same time that i took my car to the dealership because i heard a crackling noise under the engine and the dealership told me that my exhaust heat-shield was rusted and that was causing the noise so they just took off and
they said i was good to go, the crackling noise was gone and i was happy. I dont know if its me but i think the backfiring got a little bit louder. is this
normal for a stock exhaust?

Tonight when i was pulling into a private property i turned my DRL's off by pulling my ebrakes just a bit(without them actually engaging) quickly flicking the key back and forth while the revs were around 3-4000 while the car was rolling around 5 km/h.(this was the second time i did this)

The car was never shut off and when i was on my way home i noticed the backfiring got really louder. It was a loud popping noise. I tried to do some searching and found a thread that matched my experience tonight.

Here's the thread:https://g35driver.com/forums/intake-...ust-trick.html

Anyone would like to give me some advice on whats going on with my car?

is this the wrong section?

 

damn it noone wants to chime in?

 

Read the thread you just posted, there is an answer.
And why would you Referring back to the old thread that is EXACTLY why you are experience backfire...

 

Yea I understand that I shouldn't do that. But I still experience a slight backfire normally. What I wanted to know was is that normal for a stock exhaust? And would taking the heat shield of somehow make the exhaust louder?

 

Mine backfired all the time when i had a stock exhaust and no i dont think taking a heat shield off would affect the exhaust flowing out of the engine and through pipes.

 

ok thanks.
