| Complete Exhaust For 86-92 Turbo II |
Part Number 16425 |
| This complete exhaust system is 3" out of the turbo, 3" Pre-silencer, then splits into two 2.375-inch pipes into the two mufflers. The system is constructed of 100% stainless steel, with stainless packing in pre-silencer. Mufflers and tips are polished stainless. |
| HP increase is approximately 32% (a 59HP increase) on a 1987 Turbo II. Boost increase is 4-6 psi. Fuel cut controller is required to prevent fuel shut-off to rear rotor due to the increase in boost pressure seen by the factory computer. |
| Fuel Cut Controller | |
| The Fuel Cut Controller allows the Turbo II to run at higher-than-stock turbo boost pressures without experiencing pre-programmed rear rotor fuel cutoff. The Fuel Cut controller essentially deceives the ECU (computer) into thinking the boost is not as high as it actually is. Consequently, the stock boost gauge no longer displays accurate boost pressure. Boost gauges can be found here. | |
