2015 - 2020 Subaru STI Downpipe 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 2015 - 2020 STI Downpipes are available with a high flow race catalytic converter, an optional GESI cat.

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 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.

Great product I just got it installed. Exactly what I wanted in a product. Thank you

What you would expect!

MAP has done great with their in-house products. Quality is second-to-none and helps achieve that nice tone to your exhaust note (depends on what exhaust you run with). I have a pro-tune and couldn't be more pleased!

Throaty and deep exhaust, quicker spool

The downpipe is well made and sturdy, no problems with fitment. When used with the MAP Stage 2 OTS tune, the car pulls just a little harder than the MAP Stage 1 OTS, but spools about 500 rpm quicker. Exhaust note is more boomy and clear, and the catback really trumpets on WOT. Very happy with this!
