Thermal shield for cats looking for dimensions

[72hemi]

Ok so I am looking at installing some thermal shields on my catalytic converters and was wondering if anyone knows the dimensions of the stock cats on a gen 2 coupe and if anyone has used this product from Thermo-Tec? Being that this product is 24 inches by 40 inches I think one would be enough, but I want to place only one order, so if I need two I want to know that up front.

Dont know about that stuff but i bought some exhaust wrap from Roe Racing for Gen 3 side exhaust bc the other we tried was getting sills too hot and the Roe Racing stuff worked awsome. Went from not being able to touch side sills after run to laying my hand on em. It was as soft white wrap that used a sort of steel type zip tie to secure. Just a thought for ya

72, that product you are looking at is designed to reflect radiant heat. This would be installed on the inside of your sill and would need a gap between it and the cat in order to effectivly relect the radiant heat away from the sill.

If you are looking for a wrap type insulation then you have a couple options that i know of:
1. Header/Exhaust Wrap like - http://www.heatshieldproducts.com/p...d-header-heat-wrap/premium-exhaust-wrap/34/19
2. A mat type wrap like - http://www.heatshieldproducts.com/p...ps/heatshield-armor-exhaust-heat-shield/47/37

I personally would not wrap a cat with anything for two reasons:
1. Cats are designed to work at a certain temp. Overheating can cause failure. Wraping a cat will cause it to run hotter.
2. With a stock cat there is barely any airspace as it is between it and the factory sills reflective insulation. Wrappnig it would fill up the gap between it voiding the reflective abilities of the the stock insulation and inhibiting air flow around the cat.

If you dont have hi-flow cats i suggest going that direction.

The problem I have with adding hi-flow cats is it seems they don't last as long as the factory units and cost over $400. I am repainting my side sills this weekend and I want to keep the cats from burning the paint again.
