Hi
Don't forget that HKS also make the Drager 2 exhaust. This is a nice alternative to the Hiper Muffler.
This slightly different in styling and allows for a sound reducing insert to be placed in the tail pipe (but nobody does:-)
Caution ; We've seen a couple of is200's with a dual path/exit exhaust system fitted. The pipe work is not mandrel bent, the pipe diameters are very small, the collectors and mufflers are not a hi flow design. Make sure you know what you are buying before you part with your cash ;-)
