For the majority of Saab’s on the road, maximizing the stock turbo hot side is the perfect turbo upgrade.
For the outlet this means dramatically reduced dance pressure and turbulence by removing the choke point where the wastegate renters the exhaust path. Doing this modification brings the outlet opening from approximately 2.25” I.D. up to 3.0” I.D. providing a 30% increase.
Additional custom porting to match your needs are no problem.
