No downside so far
Went from stock to this downpipe the install was easy and I did it in my garage. Having tight space made it a little hard but not impossible. It sounds amazing and I love it. It caused an cel after a few km but I haven’t reflashed yet; may also need a new o2 sensor either way pipe was so worth it
