Headers & Test Pipe Installation Questions

[PUREVIL]

Wow I haven't posted on Prime much anymore... and this is kind of a stupid question but Im going to ask regardless. I bought a used set of DC Sport headers from another member and they are in great shape, I had them ceramic coated to make them look new again. My question is will I need new gaskets for the headers and test pipes? I think YES is the answer, but my question is where do I order them from? Will the standard NSX exhaust manifold gaskets work? Or do I need to order them from DC Sports? Thanks.

Get OEM gaskets?

Some people reuse them I prefer new. Be sure to torque the nuts down evenly and to the right spec per the manual.

+1, I also bought new nuts since the old ones tend to rust. A small investment.:smile:

be careful not to snap the exhaust mainfold studs when removing the old one.

New OEM gaskets and new nuts check.... but where do I find the torque specs?????

Use high temp, gold anti-sieze on the studs before you install the nuts. It will make your life much easier if you ever have to remove them for a pan gasket or ...?

If all you have is an lb-in torque wrench set it to 300. I just did mine. (Drove it to work this morning. It only took me about 6 weeks to install my headers and exhaust, CV boots etc)
I did mine in three steps, 150, 250, 300.

Not trying to put more work on you but since this has been discussed before, let me add. Check your oil pan gasket very good. Any sign of seepage I suggest installing a new pan gasket. It's very easy during header install but once headers are in place, the header must be removed should the pan start to leak down the road. The gasket is cheap insurance.:smile:

Well mine isn't leaking or seeping, so should I still replace it? Im ordering a few parts from acura like the aforementioned gaskets and nuts, but also new AC gasket cuz that was leaking, wheel well liner cuz mine cracked from my side skirts. So I can have them throw it on there as well.

Ask Larryb. It took me an additional 30 minutes. But mine was starting to seep at 53,000. I think I pd. 30 bucks for it.

those look sweet, but im looking for black wheels this time around and the TE37s are another timeless wheel that I love. But I seen another set of Volks that were black with a red strip and they were badass.
