This twin scroll edition features a ball-bearing cartridge, billet compressor wheel , and 10cm2 housing. Thanks to the billet compressor wheel the overall weight of the wheel is lighter than competing turbochargers and allows for maximum airflow throughout the unit with the help of point milling on each blade. A unique wheel and blade design, featuring a 20% larger wheel with 17% longer blades than the factory turbocharger. In addition, the GTX2971 features a port and polished exhaust housing to minimize exhaust flow turbulence. All hardware is included with purchase.
Catered to the die-hard Subaru fans! The twin scroll turbo is an efficient way to replace or upgrade your current twin scroll set up on your Subaru. With the rarity of twin-scroll turbo applications, we have created yet another direct bolt-on system, this time for the 2002-2007 WRX and 2004-2018 STi. The GTX2971 is already an efficient turbo but now paired with a complete twin-scroll system, spool time is dramatically decreased!
The Twin Scroll High Flow Catless Downpipe features larger diameter piping with ported flanges for a quicker and faster exhaust air flow compared to the standard OEM downpipe. Each downpipe is constructed of SUS304 grade stainless steel that gives it shine and durability that will last for years to come. Installation is a snap! The downpipe will fit like your OEM downpipe and comes with all the necessary hardware and gaskets.
The Twin Scroll Equal Length Headers feature a lost wax finish with 3-1 connectors and a smooth inner surface for the best air flow. A stable & effective connection s made by the slip joint bracket and air leakage is avoided by the 3 bolt flange design up-pipe.
All in all the entire system will bolt together without any issues and make way for quick installation, having all components sit in their stock locations in the engine bay.
