Default What size is the hks hi-power exhaust?

Hey guys ive been curious as to what size (mm) the hks hi-power exhaust is? When I read the descriptions on the sites that sell them they just say they vary from 55-95mm.

The Hi-Power made for the S2000 has 60MM piping and 96MM tips.

Other models for other cars have as small as 55MM piping, but not the s.

isnt the stock exhaust about 61mm? why would hks make an exhaust smaller and more restrictive than stock? and wouldnt i just be hurting myself using a 63mm test pipe with the 60mm hks exhaust? (bottleneck)

I have no idea how big the stock exhaust system is, but I do know that the Hi-Power is not meant for any gains.

single 70mm FTW!

even tho im rocking the Apexi WSII..

I occasionaly wonder if I should keep the mufflers and change the 63mm piping to 70mm, cause my exhaust sounds daaamn good.
