The APEXi Down Pipe is the pipe on turbo vehicles that connects the turbine exhaust housing to the catalytic converter. Although short in length, the APEXi downpipes provide incredible amounts of power because the piping diameter is enlarged so early on the exhaust system. This enlargement in diameter results in a dramatic increase in exhaust flow capacity as well as a significant reduction of back pressure. The GT spec Down Pipes are constructed of fully polished SUS 304 stainless steel.
For maximum exhaust flow and increased turbo spool up, HKS offers Off-Road down pipes and front pipes for race use. Each 75mm mandrel down pipe and front pipe is a bolt on application that will mount to the stock turbo and to HKS turbo upgrade kits.
Injen Technology Forced Induction Parts offer additional performance for the turbo charged vehicles. Downpipes are carefully engineered and tested to offer some of the best aftermarket upgrades in the market.
High quality down pipe for maximum turbo performance. The down pipe is a critical component in turbo machines and TANABE TURBINE TUBES increase torque by increasing the flow of compressed exhaust gas form the engine. The powerful down pipe enhances turbo performance dramatically by quickly increasing torque from low to high revs and was developed and refined through TANABE"s years of participating in racing. A mount hole is conveniently added for optional installation of an exhaust temperature sensor. For users who want sharp exhaust response and full range power from turbo engines. Best when combined with a TANABE MEDALION series exhaust system.
