Just got new dual exhaust put on and the guy at the shop said to spray hi temp paid inside the muffler, let it sit for 2 hours and repeat the process. He also said to clean it with brake wash and silicone spray. Does this sound right? I might of mixed it up

 

What the ****...

 

to stop rust im guessing?

 

On the inside of the pip...where it's hot as hell and going to be coated in carbon no time flat.......I dont' get it.

 

Sounds like a ferry tail to me.

 

What is a good idea is to put some antiseize on the places you clamp the pipes together so you can take them apart later.
