I own a 99 GSX and have the HKS HI power system it sounds really good at WOT and a pretty deep throaty rumble. Not too loud but not too quiet. I do believe it just says HKS HI POWER but im not possitive. It looks real nice and performs just as good I would definitly recommend this system. Good luck

is it 2.5 or 3"? I heard that it's 2.5 inch for downpipe...

i got the hi-power exhaust and i love it....perfect tone......i have the 3 inch and i believe it necks down to 2.5' maybe even 2.25' where it hooks up to the cat......in order to by pass this problem you can go to a muffler shop and have them cut the necked down part of the exhaust and weld on straight some piping that accomodates your desired inches for the downpipe or hi-flow cat you plan to use to eliminate all restrictions
