Invidia Subaru WRX and STi Bell Mouth Downpipe. Invidia's all new downpipe is a great way to start adding Horse Power and Torque gains. This system was tested in turbo magazine. When combined with the cat-back section, HP gains were seen up to 60+ at the wheels with engine managment. The downpipe is constucted of 304 stainless steel with a large bellmouth will ensure longevity while enhancing power by freeing wastegate gaskets. 3in" mandrel bent and bolts up to any catback or stock unit.
Only one O2 bung. If you need two, purchase part number HS02SW1DPO.
High quality part, great fitment and really helps wake up the car. Definitely a must buy and a great price. I opted in for the upgraded grimmspeed gaskets and they were great too
Welds are super clean, feels very high quality. The install was relatively simple as well. Excellent turbo noise! Very much worth the money! Also shipping was very quick!
The downpipe fit perfectly in my 2006 sti and paired with an invidia n1 catback, it really woke the car up and it sounds amazing! Good performance gains and a great sound.
Excellent quality downpipe for my 2002 WRX. Good quality welds, and it fits tightly to the body so that if your car is lowered, like mine, there's a lower chance of scraping on stuff. I paired this with a turboXs catback, and the exhaust note is amazing with tons of turbo spool with a nice deep rumble. I highly recommend this combo.
