SC: Yes, out the exhaust pipe. I personally don't think you'd be able to see them, though. The ALS combustion should be happening before the turbo in the exaust manifold if you want to get the desired effect. I'd think the turbo and long length to the back of the car would cause you not to see the ALS flames themselves.
But any fuel not burned by the ALS or by regular combustion may light off in the exhaust pipe and cause flames to shoot out the exhaust.

Yeah, ALS doesnt shoot that many flames normally, but it also depends on how high you set it: you can set to to be around 5 PSI (good for fast road or track) or like 15 PSI or more (for rally) 
From inside the car, mild ALS sounds like you're driving over small gravel (small stones hitting the wheelarches and the underside of the car). When you come out of a hairpin and floor it, the car steps sideways immediately Quite an experience

I guess if you have a full exhaust, ALS flames might be less likely seen. In my case, when I was using ALS on my Talon, I had a shorty pipe off the turbo dumping immediately below the engine. You'd see that sucker. :-) Set ALS to 10-15 degrees ATDC and watch it light up. Not so bad on the turbo for drag racing purposes, but kills 'em quick on a road course or rally.

So I hear everywhere, Speedlimit, and I guess it's generally true or it's information from when turbos werent as good as they are nowadays.
However, the Evo turbos just seem to last forever. My rally team have run a whole season or maybe even 2 with one turbo! And my friends who run ALS on road Evos have no turbo problems...

FWIW, the EGTs measured in my exhaust manifold while running ALS were "only" 1650F or so. Not too absurd if you're worried about melting turbine housings or wheels or whatever. I run 1600 or very close to it for extended periods of time down the drag strip, so short burst from ALS probably isn't going to kill the turbo.
Sorry to be so off topic. That car just inspires tech racing discussions.
