Wondering how much louder the Nismo exhaust is compared to stock.

 

Do a search for Nismo Clip. You should see something from Konverter. He did like 3 or 4 video clips.

 

I did listen to the clips of the different exhaust types, but could not tell too much of a difference. Only that some cars did backfire more than others.

I guess the best was the comparason that Konverter did with the dB meter on the dyno.
