I just installed DC Ceramic headers on my 2006 Xb today. Part #: SHC4401 from DC. Supposedly no one has had any problems with them on an 06, but here's the problem I'm having.
The install went fine and it is snug against the exhaust manifold, but when the header goes down to meet the down/cat pipe there is a donut that fits on the end which is in good shape no cracks/etc (this car has 900mi on it)and that forms the seal along with the spring loaded bolts. But no matter how many times we reseated everything (4x to be exact) I still have a leak. And its definately more pronounced under throttle/WOT.
Does anyone have any suggestions on how to fix this? I can't go around with that leak, while it's not going to cause any major issues, I'd like it to perform properly and give me a proper sound. The only difference is that in the stock header there's a bracket which bolts it to the frame which keeps the assembly rigid, but on the DC headers it does not have that. I'm wondering if I could somehow seal it with some flexible high-temp silicone just to close the leak?
Any help would be greatly appreciated.
Thanks!
