I don't think this happened all of a sudden .. but damn, my greddy catback exhaust has gotten annoyingly loud.

I'm also hearing slight 'farting' noises at low rpms. Any ideas? I only have the greddy sp catback exhaust .. stock ypipe.

any ideas to fix this or check?

thanks!

 

check your y-pipe to make sure it is still in good condition.

 

Where is the Loudest part coming from? Engine bay, just behind the firewall, tailpipe?

I know on 3rd gen maximas our exhaust studs go out, along with our motor mounts which all add up to exhaust leaks right around the flex pipe, in fact my flex pipe has broken completely off from my exhaust system. I kinda have that trucker/open header sound now.

 

check flex pipe

 

thanks for the tips guys.

I looked into the problem some more ... the extra noise is coming from underneath the front end of the car. ..

couple months ago, I had my shifter bushing replaced w/ those urethane ones .. i'm thinking when the cat was dropped, it wasn't installed properly or some sort of gasket went bad?

 

That or the flex pipe broke when them cat bolts were gettin snapped

Those 4th gens are getting pretty old now, so you will start to see a lot of the same stuff us 3rd gen owners deal with daily...

Enjoy.

 

Exhaust leek?

 

yeah most def. an exhaust leak around the cat area ... the extra noise iscoming from there.
