2008-2021 Subaru WRX STI / 2008-2014 Subaru WRX Downpipe Upgrade by MAPerformance

When the turbo compresses exhaust gas, its forced through a narrow OEM downpipe on its way through your exhaust system. This narrow pipe creates back pressure & reduces exhaust flow leaving your car short of its true power potential. MAPerformance has crafted the perfect solution to unleash this power and is proudly offering it to the eager 15+ Subaru STI market.

Designed to last a lifetime, the MAPerformance Subaru Downpipes are available with a high flow catalytic converter.

Built in-house from 3" mandrel bent 304SS piping our semi-divided head pipe maximizes exhaust flow and helps to eliminate unwanted boost creep. Utilizing a thick 1/2" stainless steel turbo outlet flange, high-quality interlocking lined stainless steel flex section and sporting an additional O2 bung, this STI downpipe has been designed to outperform & outlast our competitor's offerings at a price point that won't break the bank.

Mating our MAPerformance Subaru WRX / STI Downpipe to an OEM factory exhaust or aftermarket exhaust is a breeze. Simply select the option you'd like in the drop downs above and we will include all the necessary hardware.

Too Tight but It Works
It doesn't really sit on very well to be honest, it tends to sit TOO tight in my opinion. Taking it off can be a hassle but at least it gets the job done, durability is good, finish is great, obviously easy to use.

Perfect fit
This product was a perfect fit on our 2009 BMW 328i. It was alittle difficult connecting the hose at the bottom because my husband has big hands but I was able to help tighten the screw Due to my smaller hand size Overall very good product and fast delivery
