And I have had the HKS Sport 85 mm cat back for a year now and love it, great product, great welds, no install problems, the sport has same 85 mm pipe but with a traditional muffler and single tip, cuts down inside noise significantly compared to hi power, flow is still great, but under 3k its insanely quiet, above 3k sounds just like the high power but doesnt pop and spudder when you let off the gas.
I picked mine up online from an hks vender jsc speed for about 400 bucks, zero issues and alot of compliments on the pipe. IIRC the above guy needs to remeasure his pipe, the hi power is generally a 75 mm pipe with a 85 mm tip on it, my sport is 10mm bigger pipe going to the muffler, probably to account for the back pressure this muffler has. so if you were going to go turbo you would already have a pipe that is over 3 inches, just hack the muffler off and add a fart cannon if thats what you want.
I almost got the hi power till I realized nobody was rocking the sport and that generally the straight thru mufflers all sound very simular and fucking loud, so thats when I looked at megan type 2 which has reports of the packing burning out , the apex noir which is spendy, and the brm magna flow setup which I have driven a 240 with and its fucking loud and has grunt, for a daily I thought it was a bit too much but sounds better than all others Ive heard, so I gave hks sport a try, it has the low tone of the brm with out the resonince sounds.
Alot of info here, just giving my 2 cents, I have had a straight pipe, a resonated drifter art of ryo exhaust, a pencil tip fart cannon and now the hks sport,,, maybe I am getting old but this doesnt get me pulled over nor does it sound too quiet when I give it gas.
All testing done on a 98 without a cat, if you put the cat on the other exhaust systems prolly sound awesomely quiet too
