New exhaust has surface rust?

[BigRAWesty]

Was only going to wrap manifold, and dump. And then run a Bennie on the turbo.

Every bolt i take out i put never seize on. wouldn't hurt but as 4bye4 said the heat from the exhaust will dry out any moisture.

Do You mean beanie, if so If had mine on for well over a year now
Ive found no down sides to it just positives only. Thermal dynamics oh yeah

Thanks for all the replies and just thought I'd update.

It took about 3hrs of knuckle-busting to remove the factory exhaust and an hour to get the new one in. Probably should have washed the underside first but I didn't and ended up with plenty of dirt and dust dropping into my face.

I didn't reinstall the heatshield around the dump pipe because I'll need to take it off again soon: one of the bolt holes in the flange that joins to the turbo won't let a factory bolt fit into it so I'll need to resize the hole a bit or find a stubbier bolt, and the pyro bung (1/8 npt) is too small for the VDO EGT thermocouple fitting (1/4 nptf) so I'll need to get the VDO bung welded on or find a new fitting.
I figure I'll look more into the heatshield / wrap / turbo beanie once the dump pipe is all sorted.

Also, the larger diameter of the exhaust meant it was now high enough to touch the dangling wiring for a reversing light I added a while back. The fuse for the dash/OBD II/etc was blowing and I couldn't figure out why! Spent some time under the Patrol to look for any wiring I might have knocked loose from fitting the exhaust, and eventually found the reversing light wiring sitting on the top of the exhaust and the insulation had melted through and the wire was touching!

All in all the small (but noticeable) change in low-rev responsiveness is nice for the RD28. The exhaust note is nice and even though it's quite loud under throttle, I like it. I can get some audio/video if anyone's interested.
It was a cheaper exhaust (http://www.factorydirect4x4exhausts....ler-with-pyro/) and the quality is what I'd expect for the price range, so we'll see how it fares over the next few months.
