Hi Guys,
Im from South Africa. Driving a 2005 Honda S2000.
Just added a K&N filter. Now want to upgrade the exhaust system.
Going with 3" pipes 4 into 2,then when coming to the OEM tail pieces, they look smaller than 3".
Are there other tail pieces that look like OEM that have a 3inch opening or if i use the standard tail pieces will it reduce power gains?

Im not too clued up on mods for the S2k or mechanics in general so help would be really appreciated.

Thanks!
