The factory uppipe contains a flex section that collapses over time and a catalytic converter that restricts exhaust flow before it reaches the turbine wheel. The Cobb uppipe removes both restrictions, improving exhaust gas flow to the turbine and reducing the heat buildup that the factory flex section traps.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0737\/9029\/2257\/files\/ed4cefae09ffb1bb88775ff26d09e9ea.jpg?v=1776397687\" alt=\"Cobb Stg 2+ Drivetrain Pkg w\/ Weighted Shift Knob - Black Knob \/ Black Lockout - 2004-2021 Subaru STI 6MT\" style=\"width:100%;max-width:100%;margin:20px 0;border-radius:4px;\"\u003e\n\n\u003ch4\u003e\u003cstrong\u003eBetter Flow to the Turbine Wheel\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eReducing restriction in the uppipe directly improves how quickly exhaust gas reaches the turbine wheel on the Subaru.

Based in Austin, Texas, Cobb built their reputation on the Accessport — the most widely used Subaru ECU tuning device on the market — and expanded that into a full ecosystem of intake, exhaust, drivetrain, and engine bay accessories engineered specifically for the platforms they support. Every Cobb product is developed in-house and validated on their own test vehicles before it reaches customers. Subispeed carries the full Cobb catalog because their engineering standards and platform-specific development process consistently produce parts that work exactly as advertised.\u003c\/p\u003e\n\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eYear\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eNotes\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e2004-2014\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eSti\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e2004-2021\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eWrx Sti\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"COBB","offers":[{"title":"Default Title","offer_id":45712246079574,"sku":"COBB215X02P-W-BK-KNOB-BK-LOCKOUT","price":147.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/0411\/1190\/files\/71nbqik9iyps_ef3a3e8a-88a1-480a-9860-399004d2f630.jpg?v=1788778919","url":"https:\/\/truegearus.com\/products\/cobb-stg-2-drivetrain-pkg-w-weighted-shift-knob-black-knob-black-lockout-2004-2021-subaru-sti-6mt-1jm4tm","provider":"TrueGear","version":"1.0","type":"link"}
