Hi, I have a 2003 g35 Sedan and I wanted to know what I could do (for cheap) to upgrade my exhaust and make it a little bit throatier and maybe crackle a bit. Lately, for some reason, I've heard very very tiny crackles once I let off the accelerator which I love. Is there any way to amplify these? Down pipe? Y-pipe? I'm not sure what the best option would be. Thanks!

 

Change the factory resonator to an appropriate sized Magnaflow or Dynomax resonator.

Is your exhaust rusty? The crackles could be rust pinholes in the exhaust system.

 

Thanks for the reply! I'll look into that. I think you're right about the holes, I do believe I have an exhaust leak.
