1. I did the research here and other sites but haven't really found anyone using these with 350zs. But my question is there an alternative to this muffler that will work with the350's stock exhaust system? By the way if you havent heard of them before they are just electronic volume controlled mufflers. Where I'm at too much attention isn't good so something like this would be great. Also if anyone have a recommendations for a catback exhaust system that isn't loud till higher rpms I'm willing to check them out too.

 

Fujitsubo is one of the quieter options.

 

Nismo catback which is actually made by Fujitsubo.
Just wondering,who sells Varex in the U.S.?
I've read about these remote control/butterfly mufflers in Australia.

 

apexi makes spring loaded dampers for the exh tips for 120 mm tips.. search for those. maybe a good option.. mechanical w a spring.

 

Most quality systems are this way. Even the Motordyne Shockwave is pretty quiet until you stomp on it.

Nismo S-Tune and Fujitsubo systems are also fairly quiet systems, more free flowing than stock but barely any louder. They are the same design, they are not both made by Fujitsubo.

 

Which one are you referring to?

 

The Nismo and the Fuji.

 

They also make this silencer.

 

Actually, I believe they don't but I contacted the site and they're willing to ship.

 

Actually that's pretty much exactly what I was looking for, I was only looking for a quieter exhaust because I wasn't seeing any 350z exhaust systems with butterfly valves to quiet them down if need be. so I'll just go with this and probably some other exhaust. Thanks for the help

 

Wow, someone invented a way to completely block up the exhaust, where can i buy one!!! :/
