MAPerformance exhaust 2015-2021 WRX/STI

The estimated shipping was 10-14 days but it arrived in 6 days. I own a 2019 WRX and this is the first mod on the car. The exhaust gave my car a deep time with a refined sound. I did a lot of research before purchasing this exhaust and I couldn’t be happier. The exhaust roars when you step on it, but it isn’t too loud. The burnt tips look absolutely beautiful as well. This is exactly what I was looking for. Thank you MAP!

Exhaust

Looks great and my husbands car sounds awesome, the only complaint he had was that there were some clamps missing and we just had to go buy those.

Perfect sound for the WRX!!

The MAPerformance exhaust with mufflers is the perfect sound level for anyone who is looking for that quiet sound when cruising, but yet roar when you step on it!! Especially paired with the MAPerformance J-pipe!!

Makes me feel like I'm in "stealth" mode. Although I did ended up purchasing the muffler deletes as well for the cat-back so that I can swap them out for the weekend cruise, or just to make some more noise with my Burble map.

Don't let the v-band clamps and connectors scare you away from purchasing this exhaust.

I was skeptical at first, but now I actually LIKE the fact that the system utilizes v-bands and clamps. Gives you more room for adjustability, easily remove axle-backs AND eliminate the use of gaskets.

High quality, as always from MAPerformance, highly recommended!!
