I heard the Fujitsubo's taper like hell. Is that true? I remember someone hacking up his Fujitsubo and finding this big ole' taper inside.

 

I have this catback along with dp and test pipe and its very quiet. Even while going WOT the car is very quiet and stealthy.

I switched from a helix catback to the fujitsubo rm01a and I did notice a little loss of power on the butt-dyno but the reduction in noise was worth it for me.

This catback would most probably need an exhaust shield on the rear bumper otherwise you get that black crap on your rear bumper but this could be avoided if you put on the jdm bumper.

 

Looks good.
