Default Heat Wrap Question,

I've checked around the forum, but no luck on what I want to know. I bought this downpipe from a friend that sold his car. I just finished heat wrapping my headers and just getting to this.


******That net/filter-like looking thing right before the cat. It's flexible and I don't think any piping is under it. Is it a good idea to heat wrap over it? or just leave it be?**********

I'll be coating it with Ceramic then heat wrap

Just leave it unwrapped you don't need the wrap any further then that.

That portion is known as a "flex pipe." You really only need to wrap down to the bend of the pipe, if you want you can go clear to the end. Honestly makes no difference.

I thought so too, saw a lot of people wrap just down to about there. Thank you so much for the help.

If you're coating it, dont worry about heat wrap. If you still want to heat wrap, as has been said, only go to the bend. Anything after that and you're asking for it to fall apart.

You only need to wrap before the turbo.

to the bend! after that road debris will start to tear it up and it'll fray and fall apart and so on. If you're ceramic coating it though I don't know if I'd even worry about it.

Don't wrap the flex section, it can cause it to fail prematurely
