To Flash or NOT to Flash?

So I am done with all the bolt-on power mods that I wanted to put on my M3 the only mod left to do is a flash. At this point I am sure that I want to go with the ESS catless flash. my question is for those who have the flash was it worth the money, is there any notable power gains or did you flash just because you wanted to get rid of the cel and remove the top speed governor?
I am on the fence because I still have my stock xpipe with cats attached and can reinstall myself for emission within the next two years, I have done 172mph so I'm not sure about the limited top speed of my M3 yet (I know the M3 is supposed to be governed at 155 but mine is not); don't see myself doing more than 180mph with the M3, I don't care to extend the rev limit as I feel it is ok stock. So guys talk me into or out of doing this mod . Also for those of you who did not go with the flash chime in. Also is there a need to go one step colder plugs I had to do this with my Flashed G35.

I'm not a huge info based guy but I have the ESS direct flash tune and I love it. By no means does it make the car feel like its supercharged or anything like that but you definitely do feel the difference.

Agreed with CCL16M3. Also have a Challenge Street (stock primaries intact) and Remus Sport with the ESS tune. Not sure how much the exhaust mods add to the mix as I did it all at the same time. I likie none the less. The only thing I miss is the sound of the cats warming up. I guess the exhaust makes up for that...

I'm waiting for my ESS tuned files as we speak. Will start a thread with impressions after some time behind the wheel.

I purchased another stock xpipe off someone because I did not want to cut mine, then I had a custom test pipe welded to the xpipe. I like this setup better than an aftermarket xpipe because you still retain the secondary cats that do not restrict power, the exhaust smell is toned down alot in my opinion when compared to another M3 with aftermarket xpipe with cat delete and you save money, most xpipes are over $1000 not worth it there are no power gains from an xpipe.
