I'm looking for the same thing you are! More power to the wheels, and a nice sound! Still not sure if I even need a header, since the intake/exhaust manifold is one piece. Maybe just need a new ECU piggyback, and high flow cat converter. I think the pipe from cat back is already atleast 2.5 inces(correct me if im wrong). Anyways im sure they won't come out with these parts until the Si is officially released in Dec. They wouldn't like an EX speeding past a new Si. :driving: :driving:Phun Siz said:Sounds like it could be a good Xmas.
I'm ready to do something with my EX Coupe M/T. LOVING it! I have about 1700 miles over 3 weeks.
Would love to do an ECU, intake and exhaust. For me, something that empasizes the low-mid range where I spend 95% of the time.
I'd like to find out how the stock EX rates. How restrictive is the intake flow? How restrictive is the stock exhaust? If I am not going turbo/blower (yet) then is piping ok with a replacement muffler? And do I understand correctly that the intake/exhaust manifold is some kind of one piece unit that feeds direct to the cat? That sounds like it's going to be an added expense if you want to do headers.

Yeah, if the pipe is 2.25+ then don't need it any bigger unless you are boosting. I'm not sure what the '06 EX has.~racnjsn04~ said:Still not sure if I even need a header, since the intake/exhaust manifold is one piece.

Maybe "they" won't, but I would.~racnjsn04~ said:Anyways im sure they won't come out with these parts until the Si is officially released in Dec. They wouldn't like an EX speeding past a new Si. :driving: :driving:
