A few months ago I installed the fujitsubo legalis-R and jic y-pipe on my 2006 Z It is a pretty quiet setup and it took out a lot of the 'hollow' tone that is characteristic of the stock Z exhaust note and it made everything a little deeper. Then about a month afterwards I installed a JWT Popcharger and what I have noticed is that the overall sound is still a bit deeper than stock but now there is a little of the 'hollow' tone again. It's kind of weird how that happened and it actually sounds pretty cool (especially at WOT) but anyway, just a weird thing I noticed.

Anyone else notice this with the fujitsubo or any other exhaust systems?

 

popcharger helps you hear the engine through the intake. the stock airbox is sound-deadening...

If you don't like it, the 2006 airbox is almost as good as the popcharger...

 

I really do like the sound of my setup....especially when I open it up while driving next to a wall or jersey barrier....sounds like a race car I guess that hollow tone is characteristic of this engine.

 

Racecar, BWAAAAAAA!
