Rattle Noise after installing Header
Posted: Fri Apr 25, 2014 6:02 am
I just recently installed the GWR ceramic street header. Before this install, I already had the GWR midpipe and Q muffler and also MS CAI. I did not have any rattles until after I installed the header.
The noise is not very loud. I can't hear it during idle. Only momentarily when I blip the throttle. It only happens during engaging the clutch on first gear. After that I don't hear it. I hear it the most in parking lots where I am going slow and probably engaging the clutch a few times.
I would describe the sound similar to that of a diesel. Almost sounds like a rattle in the engine. Of course it is not that loud and only occurs for a moment when I engage the clutch.
The fact that I didn't have the noise before makes me think that it's not the midpipe or exhaust? I'm not sure what part of the header it could be. There are only two connection points. One to the engine and one to the midpipe. I'm pretty sure I torqued these to the proper settings. I looked under the car and the exhaust doesn't appear to be touching anything. I suppose I can tighten things up to see what happens.
I do notice the noise less when the car is cold. It seems the noise is more prevalent once the car is warmed up. Is it possible that there is something going on with the cat in the street header?
Does anyone have any ideas?
