you really don't NEED 3" exhaust until you get into the 500-550+ RWHP range.
no matter which headers you get, the Corsa is going to sound great with them. Corsa has ZERO drone.
you have a few options:
ARH short kit - $1400
Kooks headers - $1350
Stainless Works - $1250
those are the 3 i would pick from, i personally have the ARH headers, cats and x-pipe with magnaflow comp series axle back exhaust.
if i had to do it all over again, i would have bought the corsa exhaust, then one of the 3 headers above. they all are equal in quality. just be aware if you choose stainless works, to buy the kit that fits the OEM cat-back, not the 3" connections to fit their exhaust.
