Thanks for the info guys
.
I have seen the OE resonator, I agree it's not small in size but what I meant is its ability to deaden sound...I heard that it isn't great but then again that is only from info I've read on this forum and I have no real world experience.
Thanks for the sound clip ZuZu, I found your video a while back on YT and I thought "I'd be happy with that!". I wasn't aware it was with an N55 mid-pipe (with Y-pipe) though so that is good news, I can only imagine with my BMW PE it will sound a little more aggressive
