what about DEI silicon spray?

 

I used some of it when I did mine, it came with their kit....**** smokes like crazy the first few times you run it, I got some pretty funny looks sitting at a red light with smoke billowing out from under the hood

 

what does it ACTUALLY do?

 

They say it seals it against water and keeps the fabric from rotting.

 

Thats the one downside to exhaust wrap. I heard it can hold moisture in and cause the exhaust to rust and you wont even know it unless you take the wrapping off.

 

what about SS zip ties?

 

the pipes Kyle KBracing uses should not rust..
