Probably a bad idea on a non-turbo

While a turbo engine likes to see as little back-pressure as possibvle after the turbo, normally-aspirated engines need some exhaust back-pressure to stop the mixture from going straight out the exhaust at lower RPM (the turbo provides this back-pressure on a turbo car). A straight-through exhaust would give you very poor driveability with loss of torque at low RPM. You would be better off looking for an exhaust that is specifically tuned for a normally-aspirated engine.
The 3" systems offered for sale for the 9000 will only fit the turbo engines, so far as I know.
