Exhaust.. help me decide!

[90 accord]

i cant decide between the Corksport Turbo Back Exhaust, and the CP-e Turbo Back Exhaust. The Corksport will be around $350 cheaper but doesnt seem to have nearly the same amount of research the CP-e piece has.. i was unable to find any 'oem' information on the corksport piece, whereas the CP-e unit has tons of it. the full CP-e TBE has netted nearly 30 hp and 40 tq at the wheels..pretty damn impressive IMO what do you guys think?

corksport piece: CORKSPORT "Power Series" MS3 Turbo Back Exhaust System

CP-e piece: CPE Mazdaspeed3 TurboBack Exhaust System
MazdaSPEED3 3" Cat-Back Exhaust
MazdaSPEED3 3" Downpipe

the CP-e sounds better and makes more power

both look about the same

id say go with the CP-e
