Bellypan near exhaust?
 
A lot of you guys are using cloroplast for belly pans, do you leave the area near the exhaust out? Or cover that part with different material? Or insulate the pipe?

I have seen where people have cut out openings for the exhaust, and put down material. It was not on the actual exhaust piping but the exhaust itself. Others have used metals to make it more durable then chloroplast and do more to protect things, such as the transmission, from anything that goes underneath the vehicle. I'm thinking about doing an Aluminum belly pan for the added protection as being on the highway blocked in to where i could not do anything semi's have blown tires which go underneath and cause transmission bills.

A few people on here have used heavy wire mesh or screen for the places that get up next to the exhaust.

It's not cloroplast or chloroplast... ;)

If you experiment with Coroplast...you will see it might melt when it's within 1" of the exhaust system... ;)

I protected my Coroplast with some aluminum flashing. :D

Also, could face or dress the coroplast near heat sources with aluminum foil adhesive tape. At hardware store, comes in rolls like duct tape. Protects the coroplast edge, dissipates heat from any hot spots.

Also, you could fill the holes cut in coroplast for muffler clearance with aluminum window screen, which lets the holes breathe and vent heat, but still smooths the airflow of the passing slipstream.

At a thickness of 2mil, I'm not sure that would do much. Even aluminum foil would be better than that... ;)

I zip tied some crushed pop cans to the coroplast belly pan right under the muffler and it works just fine. All you want to do is get a couple cm of air between the hot part and the 'plast.

If you don't, it'll just melt a hole. No biggie in my experience, but I wouldn't do it intentionally.

I followed the Honda Insight guy's lead and wrapped my diesel exhaust in fiberglass insulation anywhere it was within 4 inches or less from the coroplast, it worked perfectly. You have to remove the paper backing so all you have is the fiberglass but to my surprise, no melted coroplast. I held it in place with aluminum tape at first and realized the adhesive might let go when it gets hot so I tied it all up with bailing wire. A year and about 2,000 miles later, no problems.

I simply covered the whole bottom, trimming only a small section where the headers came in contact with the coroplast. The result was coroplast melting in 2 other places where the exhaust heat was too much but no biggie, I just had to smell it for a day and then it sorta self trimmed itself. My plan is to buy aluminum flashing (basically a big roll of sheet aluminum that's very inexpensive and can be cut with scissors - hardware stores in the roofing section) and rivet it in as patches for the open sections. I haven't gotten to doing this part for a reeeaaallly long time and one bummer is that in the trimmed sections the heat has caused the coroplast to curl a way from the heat a little bit and made my belly pan a bit less smooth. The flashing will fix this whenever I get to it.

Just use the aluminum foil tape. Like duct tape in application, its thin foil will dissipate any heat from hot spots better than a thicker material.
