installed cti header/dp now ticking?
sorry im like spamming threads everywhere but theres alot going on with my car at once haha.
so as most of you know i have installed my cti header/dp. at first it was all good but now that im like 2 months in, ive been hearing a "ticking" loudest when cold, but doesnt completely go away. spoke to my local tech and he says it MAY be the flexpipe. tmrw ima try and get a video for you guys so ull know exactly what im talking about, but anyone have any opinions?
its def exhaust related.

Same thing happened to me with my CTI header. I doubt its your flex pipe. Grab a 13mm socket and 13mm open end wrench and go torque your header nuts down some more.
What happens is that even though they were probably torqued down all the way, the expansion caused by heating up then cooling down every time you drive your car causes the nuts to back out little by little.
This shouldn't happen since the nuts our cars come with are a prevailing torque design and are supposed to keep themselves locked in place due to having a slightly oblong (triangluar actually) shape. I think they should only be used once then swapped out for new ones.
Take a look at this pic, you'll see what I mean:
*click the pic for an extreme close up*
The dark ones are factory nuts, and the new looking ones are from the hardware store. Both prevailing torque designs, just with a different shape and obviously different amounts of wear.
If you continue to have to tighten them down to the point where it gets annoying, you may want to consider going to the hardware store and picking up some new nuts AND lock washers to keep them in place semi-permanently.
If you do decide to get new nuts, I would advise you also torque down your header studs with an E7 socket before installing them.

I actually found these on ebay, but Fastenal.com and some hardware stores should have them. I tried home depot but they didnt have nuts with the base like the ones in the pic. Sorry dont remember the torque spec. Will check in the morning.
I had the same problem with mine..
I had a ticking noise from initial installation. But I have never ridden in a 4 banger with a header so I thought it was normal.
Now that I got the flange fixed and tightened down it does not make any more noise.
