I used 16 gauge for everything but my downpipe in my first two exhausts, clean the welds and spray with that zinc in a can and never had an issue with rust, or pipes rotting at all.
I dont see it being an issue at all, my next exhaust will probably have aluminized piping in it again too.

The problem with aluminized steel piping is that it is thin and it melts. It's so thin that the exhaust will resonate and make lots of noise. I have some aluminized piping in my exhaust system currently. One section, which is about 2 feet long, and just before the axle, has a big triangle shaped spot about 10 inches long where the pipe had started to melt, quite impressive, really.

Very good info, thanks guys. I ordered 12 feet (more than enough) 304 stainless steel 3" piping from a local company to finish the exhaust off. Good thing I asked, I didn't realize that the rotary heat could even melt the aluminized steel.

Straight from RB's website:
"Racing Beat's Road Racing Header is the first step in building a serious racing exhaust system. The engine-to-pipe flange is flame cut from 1/2-inch thick flat steel. Like all of the headers we manufacture, the Road Racing Header is constructed with 2-inch O.D. mild steel tubing, .120-inch inch wall thickness, and mandrel-bends throughout."
To the OP:
Also, the OEM exhaust system is not made of SS, is made out of steel.

^ Yea how thin? 16g aluminized steel tubing is what I'm currently using on my NA 20b. I had an intake leak and my headers were glowing red hot at idle on more than one occasion. Seems to be holding up so far. I plan on upgrading the steel later when I re-engineer my header.

16G to thin? If i fired up my innovate lm1 i could probably pull hours worth of dataloggs with postturbine temps of 1800+*
Only thing that melted in that exhauyst was the core to my randomtec cat, everything else survived. i even had the downpipe wrapped.

I'm still gonna wrap it though.
May I ask, why aluminum?

How thin? RB uses .120

16 gauge works just fine, have used it for years with no problems.
This is on a N/A, but N/A have hotter exhaust than turbos.
Hell my HEADERS were 16 gauge steel for a long time... no problems!
