{"title":"2015-2021 WRX Downpipes","description":"\u003cp\u003eThe downpipe is the highest-impact exhaust modification you can make to a turbocharged 2015-2021 WRX. 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.

Above all, this 2015-2021 WRX downpipe provides a significant torque improvement in the low end and across the entire power band.

This allows uninterrupted exhaust flow from the 3.5\" 4-bolt exhaust flange all the way through the 3.0\" downpipe. The engineers also created two different transmission-specific brackets, for the 6-speed manual and CVT, to mount the downpipe to the transmission. Because the engineers know that 2015-2021 WRX owners commonly like to add wideband O2 gauges, they included an additional O2 sensor bung and plug in an ideal location for aftermarket wideband sensors!\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eTo top it off, the 2015-2021 WRX downpipe includes new turbine housing studs and nuts (which commonly strip), a new turbo outlet gasket, a new 3” 2-bolt flange gasket, and all stainless steel hardware, so you don’t have to worry about rust.
