Thread: Paint, exhaust heat question, side exit exhaust

Tweet

I have an '49 chevy with a viper V-10 in it. I am having the exhaust exit through the side of the running boards, about 6 ft behind the engine. How do i keep the tips from burning the paint? theres about a half inch of separation between the top of the tip and the bottom of the running board, so i figure heat tape or that aluminized heat shielding material (common on new cars) could go between there and shield it. But where the tip exits the running board theres not much room to create separation, what else could i do? I could get about 1/8 inch separation around it max, but it would then look sloppy. Suggestions?IMG_0898.JPG

You need to think about the heat also melting any rubber on top of the running boards to.
You will have to come up with some sort of heat shielding all around the opening...top & the sides to prevent the heat from damage.

I decided to make them "dummy" exhausts. Im going for the look, i know its not the highest desired option, but i plan on driving this, so no point in burning up the paint. Im going to have some exhaust go out it, using a Y pipe with a smaller hole (3 inch pipe, 1 inch hole, or louvers) and the full exhaust dump to the ground infront of the tires, straight out the Y. Ill make the Y pipe. It'll get a little heat, but i think i can do it so it has little to no heat transfer and make it "paint safe"

I'd put some louvers over the side hole and have the whole exhaust dump out the back. I think that look would be cool and if you ever had a car with exhaust that came out the side, you know what you're in for. The sound is loud and you can't hear yourself think in the car........been there so I know...........just my 2cents
Post some pics of this car.........I would really like to see this

A quality ceramic coating such as Jet Hot will lower the pipe temps significally plus it gives the pipes a very nice appearance. Read this to see what other people think about the coating.

yup, what Mike said on the coating!!! Works great, especially if they're coated inside and out!!! Did a set of fenderwell headers with it, lowered the temp a bunch!

My next question is... What is a safe temp to NOT burn the paint? that stuff over on the corvette forum said he dropped 200 degrees. I am going to drive this before i paint it, so i can get a temp and decide at that point to modify if needed. Either coat it or make them dummys.
