There is 4 inches of fiberglass insulation in between it and the coro. So.. 4 inches.

This is the closest I've gotten to doing a Kammback A little cleaner separation and I still have full visibility out my rear allowing for little interior side mirrors. If I do anything else it will be a full boat tail!

Nice work! Aren't you worried about the exhaust pipe melting the plastic?

I wrapped it in fire retardant fiber glass. I ended up adding some venting in the rear as the summer temps require better air flow, and it can cause issues with the gas tank becoming a safety hazard if the temps go to high.

My coroplast under panelling gets within 2 inches of my muffler and I have had no problems with plastic melting in 9 years and almost 200,000 miles of driving. Coroplast is made of polypropylene, which has a melting point of 266 degrees F.

A few questions...

-What exact type of fiberglass are you using?
-Is it going to retain moisture?
-Pics?

I ask because you might find some issues with it retaining a lot of moisture and causing advanced corrosion on your exhaust piping (and possibly the body of the vehicle itself). This will also keep a lot more heat on your exhaust piping, which has it's ups and downs (though I'm not really clear on the downs, honestly. A bit of research might be needed here).

I think you meant: Fire Retardant.

(lol, reminds me of this..)

Nice one man, hope you don't mind me copying you again!

Hopefully I'll get time to do mine this weekend. I can already feel a small difference in the length of coast just from the wheel skirts, so I think with a full belly pan I might see a big increase in the "glides"

I have everything but the plastic, and I can get pallet-sized heavy duty plastic sheets for 2 bucks each, so I'll be another 6 bucks into modding at that point.
Planning on doing a 3-piece pan, with a couple of inches of overlap and a small gap for fluid drain at each section (in case I hit high water, my area floods alot).

I'll post pics of the finished product. I posted the wheel skirt addition here somewhere the other day

White faced batt insulation. I checked on moisture after a few drives during heavy rainfall and it was damp but not soaked so I didn't worry about it after that. After having it on for a while it seemed to be retaining more moisture, so i think a better solution is needed.
