Open Header?
I heard that running an open header, meaning with out any cats can damage your motor. Is that true? Im thinking of getting a test pipe, but i dont wanna do it if it will cause problems.
any information will help.

Edit: I already have the Kamikaze Header with Downpipe installed.

Well, an "open header" usually means that you have no exhaust bolted to it. And yes it can hurt your engine by means of cold air getting up into the engine after shutting it off, thus resulting in a burned vavle. But with straight exhaust bolted on, your ok... I have RRM header with test pipe and and axle back and I'm good.

OPEN HEADER is exactly what it says open at the end of the header with nothing else attached. Running a test pipe to the header will not allow cold air back flow, which cause warp or burn your valves. Getting a test pipe is a good idea.

if you do have to drive with an "open" header make sure you ease out of the throttle, this will not allow a sudden gulp of cold air back in.
best advice, do not drive with open headers on a regular basis daily driver

Even race cars with no mufflers or cats run piping from the headers.

Dyno showing HP and Tq
Torque
HP difference
My point is don't restrict the exhaust. Don't believe the whole "You need back pressure to create Torque"
