I don't know if the supplier is reliable.
They end up around $1500 imported. So could I expect that these meet the strict Japanese rules and their quality is perfect? If so, they're worth to me.

What do you think?
SARD has been in the motor racing world for years and well known in the Japanese aftermarket products.
Many teams/shops are developing their own branded parts using the material supplied through SARD, just like the shop's own branded racing radiator using the core supplied from Koyo Rad.

Probably the first choice for the aftermarket metal CAT in Japan because of covering so many different makes/models with certificate for MOT at expensive but not unrealistic price tag.
So from that point, reliable and good choice.

As all aftermarket CATs with Japan MOT certificate are designed and tested based on standard engine, I don't know how it will perform or the durability with your FI application but at least Bruno seems to be happy for his application.
The product itself were installed on many NSX in Japan and no negative feedback on 'Minkara' website (the largest car forum in Japan).

The main pipe diameter is 60mm In/Out so please check against your header and exh backbox spec.
OEM manifold/exh backbox are twin tube structure so internal diameter is smaller than what you can see.

I think some UK owners/ex-owners used rhdjapan in the past.

Not sure Marc deals with SARD products but try contacting him at Mita Motorsports (Japan).
Very reliable (I exchange info with him as well) and he is the vendor on Prime under the name SpeedyPartsJapan.
Used to be known as theNSXshop with good feedback on Prime.

Depending on the delivery method used, it may take many days before even leaving Japan.
In June, placed order using Japan Post EMS and my package stayed in Japan for 10 days before finally getting the slot on the flight.
FedEx, UPS, DHL, etc are at extra cost but much faster.
