I am getting ready to pick up my IX GSR and was wondering what the quietest performance exhaust for the Exo is. I will probably keep the cat. converter but replace the O2 housing and downpipe.

What quiet cat back exhausts are out there that still flow well?

 

RS-r exmag, Greddy SP2, Fujitsubo (legalis), Apexi worldsport /noir. And just about any other exhaust system out there with a big drum and/or long/big and multiple resonators. The greddy is the cheapest along with the Apexi I think.

 

Just stay Stock if you don't want to be loud.

 

fujitsubo

 

fujitsubo rmo1A and legalis, rsr exmag is quiet too

you can go to fujitsubo's site to listen to a clip

 

the quieter, the more restriction, the less power...

thats y i went with a cutout.. then eventually put the electric kit on there.. i can open it when i want to drive aggresive. and close it when i dont want any attention and want the appearance of a stock car...

cheers!

 

Don't listen to Clay Aiken. Fujitsubo RM01A. does neck down to 2.5" but it will give you performance and quiet.

 

This thread should help you. Still haven't figured out why the original poster was banned. Maybe he knew to much...

well i got the hks hi power and its really quiet and looks really good,

 

i think the hks carbon ti is quiet

 

any ti exhaust will be louder then the others.

 

Might wanna check out California based companies like works, vishnu, etc.
Due to their stricter regulations, a lot of these companies make quiet exhausts.
Some of them even made to look like a stock exhaust.

 

Isn't the term "quiet" pretty subjective? Maybe if people made soundclips or something...that would work.

 

Fujitsubo RM01A !! Sounded almost like stock! I went from perrin to RM01A and its day and night difference!!

 

The one that came with the car is pretty quiet.
