I think you could Only remove it to install a aftermarket one... if you got an aftermarket one and wrapped it I think you are OK but I agree that it is gray

 

There is nothing to say you can't wrap a header. Don't know why you would want to though - just makes the header crack sooner.


I have never ever seen a heat shield on an ST Civic and there is one on the stock manifold. That being said - I've never looked at the one on the S. Does it attach the body or directly to the header?

 

The rule referenced on the previous page is talking about "exhaust heat shields' which to me means body heat shields - the S doesn't have any of these as far as I know - maybe just above the cat.

On many cars - there are metal shields bolted to the body in the exhaust tunnels.

AFAIC - the heat shield that is attached directly to the manifold is an integral part of it and replacement of the manifold with an aftermarket header does not require a heat shield.

 

True, heat wrap does wear out the header quicker. Been there done that. However, wrapping significantly lowers under hood temps, from what I've experienced. Between dyno runs I lost about 10 whp with the OEM setup, so I'm just trying to find ways to combat heat within STR allowances.

The heat shield in question is only attached to the OEM header. I'd like to remove it and try to wrap the OEM header. With how cheap OEM headers can be purchased in the classifieds, maybe it would be worth it to tolerate the accelerated wear in order to decrease temps. Just thinking out load.

TheNick, I snagged this quote of yours from a different thread in the R&C forum. Maybe you could elaborate a bit more?

I had been thinking about trying to cram a MicroSquirt Module into the stock AP1 ECU case. It would take some amount of testing to determine how best to keep OBD2 happy. Just a thought....

 

My original thoughts were the MS in parallel too. But from what I understand - there isn't enough room to do it inside the box. Then you'd also have to figure out a way to keep the feedback loop intact for the injectors and ignition without using dummy resistors. That is way over my head - I'm not an electronics guy - I'm a 3phase power guy.


edit - I've also been told that the MS doesn't support the stock cam/crank sensors.

 

Anyone have any experience with some lightweight pillowball upper mounts/top hats?


Had the car on the scales last night and was pleasantly surprised. So I'm starting to drum up solutions to all the "loose ends" for next year. The stock upper top hats are pretty heavy - so I'm looking from some lighter aluminum ones.

The only ones I seem to be able to find are the Tein's - but all the pictures I've found on Google are for the MacStrut versions that are camber plates.

 

tein makes a pillowball mount, and AST does too.

 

Motons come with them
