Will my new HKS hi power exuaust work on my stock gsr? the pipe size is 55(mm), what is the regular pipe size for a gsr exhaust and will i be able to install this myself?

 

yes it bolts up right to the catalytic convertor. i installed one and a set of comptech headers on my bone stock 2001 gsr with no problems.....make sure you have a lift....its a pain in the *** without one...its a sweet exhaust though...great choice

 

do u have any sound clip? I like my Apexi N1

 

I heard the hks hi power on a gsr recently, it's quiet when driving in 5th gear. But when you downshift or take off from first sounds deep but not loud.

 

yeah....the hks hi power is the epitamy of rice

 

the HKS hi-power is pretty much the same as N1 I think. some kid in my area has hi-power on his 95 LS. sounds pretty deep.
