{"title":"2008-2014 WRX STI Downpipes","description":"\u003cp\u003eThe downpipe is the highest-impact exhaust modification you can make to a turbocharged 2008-2014 WRX STI. It replaces the restrictive factory pipe — and on most applications the factory catalytic converter — directly behind the turbo, unlocking the power gains that a tune can then take advantage of. Expect this to be the foundation of any Stage 2 build.\u003c\/p\u003e\n\u003cp\u003eThe key choice is catted versus catless. Catted downpipes keep a high-flow catalytic converter: less smell, less smoke, and a much easier time at inspection, at the cost of a few horsepower versus catless. Catless downpipes maximize flow but produce a strong exhaust smell at idle and will not pass emissions testing anywhere it is required. Be honest about your local requirements before choosing.\u003c\/p\u003e\n\u003cp\u003eConstruction details matter here because the downpipe lives in the hottest, tightest part of the engine bay. Look for thick-wall stainless steel, a proper flex section or donut gasket to absorb engine movement, and clean welds around the turbo flange. A poor-fitting downpipe causes boost leaks and rattles that are miserable to chase after the fact.\u003c\/p\u003e\n\u003cp\u003eA downpipe requires a tune — running one on the stock calibration risks boost creep and lean conditions. Plan the tune before you buy. Every downpipe in this collection is confirmed for the 2008-2014 WRX STI turbo flange and chassis routing.\u003c\/p\u003e","products":[{"product_id":"invidia-high-flow-cat-w-extra-02-bung-downpipe-subaru-wrx-2008-2014-sti-2008-2019","title":"Invidia [08-14 WRX, 08-21 STI] High Flow Cat w\/ Extra 02 Bung Downpipe","description":"\u003cp\u003eInvidia offers both catted and catless divorced style downpipes that are designed with a separator plate between the turbine and wastegate exhaust streams.
