CATALYTIC CONVERTER HEAT SHIELD KIT - NEW

[@matteofabrizio409]

Great production value on these videos. Shame they don't have more views.

I just wrapped my cat with this stuff but, I missed the part about leaving a gap. It is part of the downpipe and in a tight spot so it would involve removing several parts to redo it. How big of an issue is it? This is an aftermarket high flow full stainless steel downpipe/cat, it should be able to take the heat without severe corrosion. Do you know of examples where this was done? If so what happened? There is a small gap, but more like 1/4-1/2" not the 2-3" recommended.

[@Heatshieldproducts]

We recommend a gap so the pipes can breathe. On a CAT you just don't want to heat up the elements too much and have them go bad prematurely. We have not heard of anyone doing the install without a subtantial gap.

@@Heatshieldproducts Thanks for the quick reply! I think I will be okay, I have seen where other vendors selling aftermarket high flow cats are also wrapping them completely. Also I have seen some stock cats fully covered with a heat shield, the difference is most of those (but not all) have a small air gap between the shield and inner wall. I think the vast majority of the cat heat goes out the exhaust and the cats are supposed to be good to over 2000 degrees. I don't see how a wrap will cause it to run anywhere near that hot. Cats run super hot like that when there is a substantial air leak up stream, and if that happens they will melt with or without the shield. I think the bigger concern would be the outer casing corroding from excess heat and moisture. I neglected to mention that this is the second time I wrapped this cat with your product. I did it 2-3 years ago while it was on the car but could only reach and cover certain parts of it (about half). I had to take it out to do other work and decided to redo it better with a fresh piece since I had full access. The one thing I noticed is when I removed the half wrap the inner insulation was damp and even had mold/mildew in it. That is when it dawned on me what was happening, the space between the shield and cat gets extremely hot, but when you turn the car off and it starts to cool that big a temp differential will cause it to suck in air and moisture as it cools. With this wrapped tightly that moisture remains trapped until the next time you start the car and it boils away, only to come back next time you turn off the car. This makes a lot of sense why wraps can cause premature corrosion on headers, cats, and even exhaust pipes, it is not just the added heat from the shield insulation keeping the heat in (which is what you want it to do), it is the constant exposure to higher heat and then constant moisture that can cause increased corrosion. I have wrapped headers before and experienced this excessive corrosion myself however, I think this really applies to steel and low quality stainless parts. I think a high quality 304 stainless steel can handle the added heat and moisture no problem. I think I am okay (we will see) because the part that was already covered for the past three years looks fine, slightly discolored but no significant corrosion. Had it been a cheap low quality stainless or even worse steel/cast iron, I think that would have caused a lot of corrosion. I think the general rule might be to to limit direct contact heat shield wraps on parts that are prone to corrosion. In those cases use something with an air gap to let it breath is a good idea. Wrapping stuff up tight is great for heat management, space, and possibly even performance (in theory), but you want to make sure that what you are covering (including the welds) is a good high quality corrosion resistant material. If not you want to use a heat shield with a small air gap (like most OEM's do), so it can breath. This is my theory anyway, what do you think?

@@ericmichel3857 You are spot on with the quality of metal. Poor stainless-steel or thin steel can lead to problems if you insulate it and do not leave room for the metal to breathe. Good luck with you project. Sounds like you are in the right path. Thank you for your purchases. We appreciate it.

[@murrayirvin3177]

Glad I found this. I have an old Mercedes and the heat shield behind the cat is rusty. I was going to wrap the whole cat.

[@2slofouru]

1-how would wrapping all around cause an issue with a stainless aftermarket cat? 2- I have a drive axle boot below mine, so need to protect the top and bottom. I just wrapped mine with ceramic wool and some stainless mesh. Maybe I should make two separate pads and leave some gaps on each side.

Y’all need to use safety wire pliers makes life so easy

[@coleblezard6628]

What temp is it rated for? I have a 2006 dodge sprinter and the cat is known to reach insane temps. Currently can’t step on the floor above it because it burns so hot.

[@Heatshieldproducts]

Thank you for your comment. A couple of things here... To answer your question. The Bio Cool material will take 1800F constant so you will be good here. To really cure the issue of your floor boards you will want to do a combination of CAT Armor and Sticky Shield. Sticky Shield is a stick-on heat shield that you can place above your CAT(s) between the heat source and the floor. This will really knock down the heat. Feel free to comment below if you have any additional questions. Thanks.

How about the serial number for the after market cat? Most likely the cars that has cats in between the radiator and the engine? Smog Tech doesn't pass cats with wrap specially if serial number are covered.

[@Heatshieldproducts]

Regarding this product we recommend you only cover half the CAT. It is also easily removed if necessary for inspections.

[@djolecar88]

Is it waterproof? My cat is on the bottom exposed to the elements.

[@Heatshieldproducts]

Water does not and will not hurt the insulating material. We did a test on KZbin Shorts which you can find in the link below. We dunk the Armor in a bucket of water and then heat it up. kzbin.infoxaZYXwzwLTw?feature=share Be sure to follow the instructions when installing the CAT Armor.

@@Heatshieldproducts Awesome! Thanks for the response. Things like that mean a lot, I'll make sure I buy your product. Thanks.

@@djolecar88 Thank you. You can also use our tech line and web contact if you want to ask a question from a live person. Ha Ha.

[@charlesmarrione587]

Glad I found you guys. I'm getting ready to replace the cats on my car. How would I wrap a catylitic converter that is in between the engine and radiator? Also, between the engine and firewall? Great video by the way. I subscribed to your channel.

[@Heatshieldproducts]

Thank you for your comment and your subscription Charles. When "wrapping" your cats with our Cat Armor be sure to never cover more than 60% of a catalytic converter. Over insulation may cause shortened lifespan of catalytic converter. With that out of the way... for all applications you need to determine where you want to reduce heat and cover that section of the cat. Normally you are looking for important components you want to protect near or around the cat. Once you have that determine you can install the Cat Armor. If you need additional help please send us an email through our website with pictures and your additional questions. www.heatshieldproducts.com/contact/

[@efalang2228]

Smog tech fail my friends car because of that, said that is covering the serial number of that after market cat. It was also in between the radiator and engine. They never mention how to wrap it with serial expose for smog purposes.

[@rockmonstr185]

Why isnt the glove guy wearing gloves?!?!?!

[@Heatshieldproducts]

Great question... We definitely recommend you wear gloves when handling Heatshield Armor.

Music is absolutely awful, and Shane is not your best demonstrator. Incomplete description. Just holding it up doesn't describe the process.
