Has Anyone Used Heat Wrap Around Their Ehhaust (Inside Rocker Panels)?

[GARY J]

I am trying to think of ways to reduce inside temperatures. I was wondering if anyone has wrapped thier exhaust system with header wrap all the way back past the passenger compartment. It seems that this would really reduce the heat radiating from the cat and muffler under the side sill. Summit racing sells 2" x 50' for $70 and it is rated to 2000 degrees. Can anyone think of any down sides? I'm just trying to perfect the car. Thanks.

You're asking for problems. Heat has to go somewhere so it will affect anything downstream. Some wrap to the cat and found the cat melting inside or the plastic where your door latches melting.

Replace cats with high flow or none.

I would think that the heat would come out of the exhaust tip, into the air behind the car...

Be careful, you may need high flow cats to handle the heat, and insulate anything unwrapped that touches the metal.

I've wrapped other vehicles with success from front to back - both reducing drone and keeping the heat within the exhaust which reduced heat soak into the car/engine bay.

Pipe life will reduce.

I've done that & it's been on almost a year with no problems. I don't have the cats on. I did it to prevent side sill blistering & reduce temps. So far so good! Only problem is the smell until it gets broken in!

one of our GTS guys wrapped his JH headers on his venom, no problems upto the cats. Baz wrapped his RT exhaust after the hi-flow cats just recently, he posted some pics

Any tight wrap will keep moisture = smell and system corrosion.

My right side sill was warm enough (with high-flow cats) so female passengers complained couple of times. I decided to run my own project. Went to Home Depot and bought air vent pipe (round shape) and three clamps. Cut the metal duct big enough to surround the cats and Borla muffler in such a way that there is an air duct through the entire sill. You need to have it smaller in front and bigger in the back so watch out, or have two separate shorter duct pieces. Covered both sides of the duct by 1300/1500 degree F VHT paint. You have to bake the sill somehow – see instructions for the VHT paint – I used Viper exhaust. It was mounted and covered by original heat shield. I admit that this was a mess to do due to a very tight space in the sill. Three people were needed to push the sill back into the place. But, the heat is reduced substantially. Still for a stop and go traffic the sill heats up (no air flow) but at the moment you roll consistently it cools down. I plan to do the same with my left sill before installing Roe S/C.

Good luck.

Roe racing sells side sill insulation.

I just bought some with my new exhaust package and it should do the trick (not yet installed)

Get rid of the cats if you don't get sniffed. Bruce

If you noticed something common here everyone who tried to wrap this didn't have a stock system. They had highflow cats or none.

Wrap a stock system and you'll melt the cat and plug it. Do it right and replace or remove the cat and then consider if wrapping it is necessary. I bet not once you try it without those OEM cats.

My cats are not stock. Neither are my mufflers.

The Roe product sounds interesting...anyone ussing it?? Sounds like a sleeve or wrap for the entire length of exh. under the sill.
