Am about to replace my decat downpipe with a grp A spec one. Now, I know exhaust wrap is good to maitain heat build up in the engine bay, would it be vworth wrapping it before replacing the old one?

In my opinion, it's a good idea, but, I may be wrong. Are they any disadvatages with this?

It's a good idea due to the fact that hot gases travel faster - therefore by wrapping the downpipe you will maintain higher temperatures within the pipe and hopefully better flow.

The only downside I'm aware of is that there's a chance the pipe can crack if it gets too hot (nearest the turbo). I've wrapped mine though.

Don't think the meaty Stainless Steel will crack. Will defo do the wrap, time to spend more money at demon tweeks!
