I finally did it and I guess I was the test dummy on the site...and i have to say I AM SO HAPPY I DID IT!
Today I had the intention on swapping RPI exhausts with my old 530i, but the shop told me that it was not possible since I have 2.5 inch piping on the RPI and 3 inch piping on my stock exhaust. SOOO, I decided why not remove all the resonators, and thats exactly what I did. After 4 hours and $400 later, I opened this beast up on the roads and boy was i impressed. It has such a deep growl but nothing too loud. It was just a couple of notches louder than the stock exhaust but nothing too big. I was expecting something louder but overall, I am extremely happy with my decision.
Let me know if you guys have any questions but the video should speak for itself
Removed: 2 Cylinder Resonators and 1 rectangular resonator

He first said he could not do it and then he said even if he was able to do it it would create a lot of "back pressure" and would not sound right...I chose the cheapest way possible and would have gone with magnaflow if it were the same price as doing this little mod

Audio and light cant really be captured real time from a recorder, what you see and hear as far as both these go is a good mile away from reality.
As for the sound we hear when he lets go of the gas,thats the noise that was canceled by the resonator before, by having noise waves intercept each other, since the resonator is gone now - The waves intercept but dont cancel each other out and instead create that popping sound.
Personally, I am going to meet up with Jashy to see how it is in Person![Hyper](https://5series.net/forums/images/smilies/imported/hyper.gif)
Really looking forward to it,
Nice Mod !
