I installed mine and noticed that the o2 bung is just bearly touching the heatshield under the car. Is this normal? I think this is where the vibration is comming from at certain RPM's. Im thinking of putting a piece of header wrap behind it. What do you guys think I should do?

 

how do you like the headers any diffrence??

 

give it a shot i did yhe same thing on my TP...and / or trim a litle bit of the heat shield to clear some space..it should work...i had same issue but on my test pipe instead, its rubbing a bit and makes a rubbing sound on a certain lower rpm, so i trim that portion thats rubbing and i wrap it with heat wrap...its all good now....good luck....

 

This header is only for the AP1 I have it on my AP2 it rattles the hell outta me lots of vibration

 

i have the header installed for like 8 months now and it have never rattled or vibrated!!!!! i have an AP2 2005.

 

the header didnt gained much but it weights a lot less that the stock one. my car gained only 1whp over stock. before header the car had AEM V2 intake and a homemade testpipe no tuning done on it. it was on a dynojet with temp at almost 90 degrees.

 

I'd like to see the dyno.

Here's my dyno sheet with the megan header. Before and after

 

my header wont even install because the bung is in under body. ive ordered new bung online and will having a shop weld it in a better position for me. im not gonna mess around with it.

 

More info plz
