You'll get engine noise more than exhaust, unless you have an exhaust leak. More sound deadening seems to be in order

 

Yep, consider a 05/06 sedan muffler as it has bigger muffler can. You'll be able to find used mufflers dirt cheap on this site, but you'll also need the 05/06 exhaust hanger which costs $45 new.

 

Get some of these, they are only $0.11





If I was old, I would find a stock sedan mid-pipe for sale on the forum and cut out the resonator. Then I'll go to a muffler shop so they install it to current mid-pipe, so you would have 2 stock resonator's inline of each other. If that don't work, than I guess the bigger 05/06 muffler.

 

+1 on the 05/06 muffler. The stock resonator on the early sedans are so big I don't think two would fit under the car. Also, like Mike@RiversideInfiniti said you might just be hearing engine noise. If you trader your stock intake tube for a Z-tube, go back to stock. If all that doesn't help, try this: https://g35driver.com/forums/audio-v...adening-g.html

 

Every time someone tries to make a VQ35 quieter, God kills a kitten.

 

Nope, not engine noise. It's the muffler.

 

Not quieting the engine. Quieting the muffler. FYI- they are on opposite sides of the car.

 

get a 05 or 06 stock muffler which is bigger than the 03 and 04's. This may quiet it down some more.
