Has anyone here installed them? Thoughts?

Thank you.

Yes, I had these DP's installed on my car almost immediately after purchase because I wanted the great sound by doing this. You will get a much better sound but will eventually set codes. And, the only way to fix that problem is to do a custom tune.

So you must have gotten catless downpipes to replace the primary cats and therefore set off the codes? I am looking for just secondary cats delete which should not set off codes as they are behind the o2 sensors, right?

I have secondary catless pipes, definitaly added some volume, but honestly interior sound is barely any higher, also yes no check engine light

For sound, I guess I might as well get x-pipes then.

For best back for the buck just remove resonator and do straight pipes. X pipe will be better but nothing compared to straight pipe. Performance wise straight pipe is better for turbos as well. There can be a big debate over x and straight and I have tried both and would do straight over X any day.
