I went with Corsa. Every time I head the ATAKs, I always thought they sounded louder.
As for the quad tips. I was going to get them but after seeing the 2018 pictures with quads... I hope that I can just swap the lower part of the bumper for much less a Roush valance.
Both are amazing sounding systems! The Borla will give you more of a deeper tone as the Corsa will have a more Raspy sounds. Both sound amazing, but it will really depend on your preference. Let us know if we can help out at all or if you need any pricing.
