I will do only downpipes first then decide if I want to remove the stock resonator. I will post vids after. My hope would be in the next month or two. ARM has a catless downpipe for crazy cheap, but they do not have any bracket for the pipe. That means the exhaust front is hanging on the downpipe which is now hanging on the turbo v-band. I am not sure if I am comfortable with that or not. I am still debating that.

The only thing is that if you do downpipes in the future, this will be obnoxiously loud.
I did this on my modified M50i . OPFs out, replaced the cats with two 200cell ones. Damn, it'a loud and a little bit drony at 3-4k rpms. Sounds like the concept M8 Competition on youtube.
I will reinstall only the OEM mid-resonators

That is exactly why I am keeping those resonators for now.

So I have a 50i and was planning on doing this exact thing, delete resonator and install straight pipes. Just curious, if you and other don't mind sharing what they paid for to do that? I'm in NY and I'm looking at pricing with some shops. Also, is that stainless steel? Does it make a difference stainless or not?

Thanks

I got my resonator delete done at joeys diagnostics on Hylan Blvd in Staten Island, paid around 200-250
They are a specialty muffler shop so i'm sure you can find cheaper if you wanted

Did you do x or straight?

And it could be me or maybe the 2nd video you sent was from further away but the first video you shared of the cold start sounds way different than this last one. Is it me? Just sounds more subdued on the initial start for some reason.

The 2nd video I had the car running an hour prior. The first video it cooled off overnight so it had a much louder start up
I did straight pipe resonator delete

I've been seriously thinking about doing this since the very first post.

Seriously concerned about DRONE inside the cabin at highway speeds. Rather than going straight pipe or X-pipe.... I was actually thinking about doing an old-school H-pipe instead, and shooting for that "muscle car" sound. Same concerns though..... Drone.

Honestly I dont notice any drone, then again im always in sports plus manually shifting city or highway so I wouldn't really notice it.
