"Flashpaks" are pretty sweet. I thought about doing them on my '95 SSEi. If you do do them make sure you do them right. There are kits out there that you can get that will help control the flame. The trick with these kits is you rev your engine to usually 3000rpm or higher and then throw a switch. IT cuts fuel to a cylinder and allows the fuel to collect in the tail pipe where it is ignited by another plug. If you still have a catalytic converter on your car it is highly recommended that you don't do this. The fuel will collect in the Cat and could possibly ignite there instead of at the tips. You would also go thru Cats quite quickly.
Long story short, I think they would look alright. Not quite as nice as on an old Studebaker but nicer than if they were on a Camary.
