Hey guys,

did a search and just foudn that it's 'OK' to remove heat shield while installing long tubes/midlengths. But couldn't find more in depth explanations giving us more of a peace of mind on how removing heat shield would really 'not harm' the car part the shield was meant to protect from the start.

Please elaborate guys! Because right now one side of my headers are touching/grazing the heat shield and I am given two options by my tech, a) remove the heat shield or b) bend the header pipe a few degrees to avoid the heat shield.

I searched and learned that option A is 'OK' but would be great if i can find a more in depth explanation on how its ok to run car without heat shield!

Thanks

Remove the heat shield it should be fine. I removed mine to install the headers, I couldn't get the passenger side on without removing it.

Wow, what headers do you guys have that you need to do that?

dleung22

but aren't the heat shield there for a reason? lol its a long shot but is there possibility something can over heat?

my car is a right hand drive car so i don't have much choices in headers. I am currently installing Innotech IPE with full Akrapovic Evo system.

Should get the car back tomorrow/day after!

Heard MHP longtubes have to remove heat shield also.

I've checked the temps around that mount with a IR temp gun and its minor. Im running MHP.

wow! nice!!

No manufacturer gratuitously installs heat shields. The manufacturer puts them there for a reason. I regularly see 127F off of the pavement in the summer. No way would I take a heat shield off...but it's JMHO, no more than that.

Over 20,000 miles hundreds and hundreds of 1/4 passes sometimes 50+ a day, couple of full road course days and zero ill effects from removing mine

I had mine LTH ceramic coated which did help in under hood heat reduction. Heat shield also wouldn't fit.

this is pretty good proof that a heat shield is not going to kill your car .

Have mine ceramic coated too(inside and outside). Definitely helps to dissipate heat. I remember I had to change an O2 sensor immediately after a dyno run and I was able to put my hand directly on the collector.

The ill effect I can think of is that over time, it may affect the paint near the area. You can always apply the stick-on heat shielding for peace of mind.

dodger63

The heat shields in question cover the engine mounts, I beloved they are there more cause of the primary cats but you guys can still talk all day about this I'm going to go out and drive mine around

Merc63

I just hammered it all the way to the tire shop. Getting new rears put on AGAIN.

Abyways, the exhaust is room temp after 10 mins and stuff around the headers is not hot. So I felt around the mount with the shield off to see how it was effected and the top of the mount near the exhaust is a warm... But the base of the mount on the block damn near burned my hand off. The block holds a lot of heat and transfers it up to the mount I'd say more then the exhaust.

Is this the new badge of courage? Are you going to beat my driving 18k miles in 11 weeks last year?

dodger63

18,000 miles in 11 weeks. Not in the 63 thanks, just saying I think we are fine with out the sheilds agree disagree its all good

Sincity

Then you will not be able to stick anything to shield it. That, IMO, is a good enough of reason to keep the shield. The radiating heat could prematurely destroy the hard rubber/hydraulic mount. Like BHAMG said, it is there for a reason.

dodger63

Well ill keep you updated if anything happens in time

Sincity

I wonder if it will fail before the other one? But like you guys say, "You gotta pay if you want to play."

dodger63

What not following,?

JohnnyUte

What about using header wrap in the specific area? I know some people have certain grips against wrap, but if it means protecting the engine mount then I may be willing to use it in a limited area. I use it in my Mustang to protect the hydraulic clutch (which prematurely gave way due to excessive heat) and haven't had any issues since. Remember, just because something hasn't happened doesn't mean it won't.

Sincity

I wonder if the unshielded mount will fail sooner than the shielded mount? I am assuming that only one heatshield is removed in this particular application.

vessproms

just remove it, its fine

hey everyone, picked my car up yesterday and WOW sounds great.
Bass is really wild, but with catless headers i think the akrapovic's bass is amplified, it is borderline drone.
But even though I am running catless it is still tolerable and i would say 'civilized'. Will make a thread later on and post a video but really, videos do not do it any justice.

However, just some questions, at the moment i am not running a tune, is it safe to drive my car short term? I know the car's AFs are different now due to headers and etc. and my engine is running lean now. I am planning to send the ECU in for tune early next week but wanted a peace of mind that car will be OK to drive safely for the next short while!

Thanks!
