Angle Mounted Cat-back Exhausts

I have a D16Y8...and i was planning on buying a HKS HI-POWER or a Apex'i N1....but i heard that the canister is angled (yuck). I was wondering if there is a way to straighten it.

(the S2000 on the HKS website has the Hi-power straight..how??)



IF now....can you list some other GREAT Exhaust Systems that have a STRAIGHT design



THANKS
