The first Japanese catback for 3IS to date by the way. What do You guys think?

 

More pics. Racing look )

 

There's an axle back in the FS section. I really wished they went with a different tip :/

 

I admire that they went with the H pipe. However I think the cat-back is heavier than ark's.
BTW any dyno numbers ?

 

They are showing an exhaust on a NX, but I don't see it on their site. Where is this?

 

RWD only big ****in surprise

 

Hmm it reads "rice" to me

 

any plans on axle back?

 

They say "YES".

 

I like the tips better on the GS, NX and RC. Can't find any sound clips for anything other than the RC though.
