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.

Running the Catted DP with a Tomei on my 2020 STI and honestly I’ve never heard a louder Subaru then now so fair warning 😂
Other then that great quality! The welds are perfect, fast shipping,!
I also bought the stage 2 map but ended up not being able to use it and they were very good to work with on getting me a refund
Purchased the catted version of this down pipe for my 19 STI and couldn’t be happier. Adding this to the MAP intake already installed and going to the MAP stage 2 tune made it feel like a completely different car. I still have a factory catback and this set up does not drone a bit while cruising on the highway. Great for some that don’t want their car too loud.
Great product and really well made ! I bought this along with the MAP Cold Air intake for my 2018 STI to get the stage 2 Map that comes included. The car sounds great and drives faster for sure! Deeper rumble and definitely would recommend.
No issues with install. Directions are spot on. I've had this down pipe for over 1k miles with the Stg2 map. The power band in the mid range has improved and it has a nice sound. Would highly recommend!!!! Awaiting plans for stg3 from MAP. I would like to see a heat shield for this down pipe to reduce under hood temps.
Very nice downpipe all the welds were gorgeous. Everything lined up except for the support bracket. Definitely made my ets catback louder than it already is.
