Hello out there, i just bought a CTR EP3 From 2003, its fully stock but got a K&N filter. I am gonna buy a DC sport manifold and Buddyclub Exhaust to it, but i was thinking if im gonna do that could the car then run badly without buying a new ECU and map it? could it run fine without doing anything to it after installing exhaust and manifold???? .. Cheers

You should be fine, i dont think it could be dangerous running this setup without any fuel management.
But for sure it is better to get your car tune

Okay thanks! What setup could etc be dangerous for the engine?

sir_2002

Running cam or being force induction could probably be dangerous i think (witout tune off course) ?!
But anyways why you would'nt buy an engine management ?
Your going to get better gain than just adding exhaust and intake to your car

With just a filter, header and exhaust I wouldn't worry at all. If you are going for power gains you obviously won't get the full potential of those parts unless properly tuned for them. But those are very minimum mods and not huge gains.

When you start messing with intake manifolds, injectors, cams, forced induction, or anything more major you definitely will not want to do it without properly tuning for them.
