Alright i have quite a few questions for anyone who wants to answer.
Im trying to build an NA motor for my Ralliart. So far im looking at parts from road race motorsports. A new down pipe , exhaust , cold air intake, and piggyback ECU are all on the list. Problem is they dont have headers for the car yet. Another problem is the down pipe is only 2.25" in diameter. The tuners in sport compact car (for those of you who read) are havin trouble with back pressure created by the 2.25" downpipe they have on the car with their turbo setup. If i decide to turbo later, willi i have to worry about this? And does anyone know if anyone makes new headers for the Ralliart?
Thanks, Cam

 

I read that nobody's making headers for the RA yet because the stock exhaust manifold is already a fairly efficient tube header. While it may be on their list of things to develop eventually, it's not near the top of it.
