Product Description


The "TB Developments Restrictor Plate" is used to add a turbulence into the exhaust system to combat boost creep often associated when fitting De-cats and Full Exhaust system that are a "little" to free flowing when using the OEM turbochargers.

Tested to add enough back pressure to allow a safe boost increase when used injunction with an aftermarket boost controller, yet still giving better power gains than if the catalytic converter was retained. Also tested to have no negative effects on power/torque or spool but allowing a manageable boost level.

These are essential for a J-Spec supra running decats and BPU modifications.
