Unknown Exhaust Header

[invader166]

I did a bit of an impulse buy today and got this 2nd hand exhaust manifold/header at a bargain price. Can someone identify it? It's definitely a 4-2-1 design.

I plan on installing it, but not sure if it'll fit the OEM heat shield. Any ideas? Will I have to heat wrap it? Or should I just install it as is and pray it doesn't overheat my engine bay? :iono:

Don't know who the manufacturer is, but in regards to the heat shield, you will be fine to go without it. Just keep your engine bay free of leaves. Most aftermarket headers cannot be run w/ the oem heat shield and are fine

Thanks for the response! By leaves do you mean flammable materials?

Also, with a bit more research, it looks like what I've got on my hands is a Weapon R header. The tag must have fallen off somehow.

Looks to be. On yours, you can see the ghost of the tack welds used to affix the tag and they are in the exact spot Weapon R places it.

yup, just keep any flammable debris from building up inside your engine bay. Likely not a problem for someone who is installing their own header as the chances are high that you inspect the engine bay quite often. But most day to day drivers rarely look inside their engine bay and if they park under a tree they can build up a lot of crap inside there.

I've noticed no excess heat or any issues since installing my DC header which is heat shield free. When you're finished the install just make sure you re install the O2 sensor bracket to the back of the valve cover, this will keep the wire from melting on the header

Cool! Thanks for the tips! I'll keep them for reference when installing it. :thumbsup:

However, isn't your DC header ceramic coated? I thought that that type of coating reduces the radiant heat from the exhaust gasses passing through. Mine is just plain stainless (no coating at all I don't think) hence better heat transfer properties, and a warmer engine bay.

Yes it is ceramic, but that being said it still gets crazy hot

Awesome! Can't wait to hear how this baby sounds!!:thumbup:

I've run my ceramic coated DC header for years without the heat shield. No issues.
