Its bolted to the exhaust manifold and all the exhaust gas is routed through it. you would have to try to find a header or exhaust manifold the was built for that car and not designed to run the turbo. Even if you were able to do this you would still have to have someone advance the timing back to where it should be for a natuarlly aspirated engine and re program the computer / change fuel enjector sizes to get the air fuel ratio back to ideal. (running without the turbo would cause your engine to run rich with fuel and cause engine fouling problems not to mention poor fuel economy.)
