Greddy Cat-back

Hi..i was thinking of buying a Greddy cat-back...i was wondering which Greddy catback (Evo, SP...) will fit my 97 LX...most of the cat-back i saw from Greddy only fits the EX type..anybody have any idea?...i'm thinking of getting the SP2 in June for 450 bucks

Oh by the way...how is the noise level of Greddy? I dont want anything real loud and disturbing..is there a silencer available for any of the Greddy exhaust?
