HKS Exhaust Q

Recommended Posts

HKS USA - which is no longer trading - used the name Hiper for their exhausts. HKS Japan use the name Silent Hi-Power.

 

HKS USA exhausts had different part numbers to HKS Japan and the exhaust designs were different.

 

31019-AT005 is the correct part number for the HKS (Japan) Silent Hi-Power for the Supra.

thanks Nic, found that when I googled it; they both looked the same but called hiper muffler in the US!

 

Surprised it is a hell of a lot cheaper to get it here versus the UK! Murraymotorsport again !

One more q, the decat pipes the supra are mainly 2.5 inch ; should you be running 3 inch pipes?

 

I think the his comes with a 2.5 to 3 inch adapter?

 

With the j-spec stock turbos it doesn't really make any difference as you need to fit a restrictor ring either way. The flange on the exhaust is the same whichever size you go with.

I cant find any information on the HKS decat pipe (AKA Mid-pipe) (Other than the Part Number-- HKS-3103-RT006) is this 3" or 2.5"?

 

Better getting the Blitz midpipe over this one because it is larger and 100% stainless steel?

 

All these Mid-pipes should mate up to the HKS Slient hi power system?
