Muffler delete 4.8i sport

Hey guys, so to day I did my muffler delete, after Mpact and Bimmerfest I saw a couple of X5's that sounded sweet so I pull the trigger...at first I was going to do the X pipe mod but our trucks come with an H pipe from factory, so thought about resonator and Muffler delete but after talking to a few people and watching some YouTube videos that option would have been too loud for my taste.
So I when with just the muffler delete and man...what a difference! At idle is just a bit louder than stock and as well, but when you put the hammer down WOW! Is a nice deep tone.

Here is a video of it, will put drive by's later let me know what you think

Nice sound.

The music is unnecessary background noise.

Sounds good. I did the same thing on my 550 but I get some droning around 1500 - 2000 RPM. Do you get any droning?

Thanks man! Did you remove anything else other than the muffler? I was told by leaving the resonators in place would prevent some of that unwanted droning, if is bad you may want to look into the Magnaflow 40 series. They have a nice deep tone. So far I am happy with it, but like anything it can get old quick. If I get tired of it I may go that route myself.

Put some sound clips of yours if you can, I would like to hear it.

I only cut out the two rear mufflers and installed quad tips. The cats and the resonators are intact. I might further tweak it to include mufflers like you recommended or I may go back to stock mufflers if it becomes my wife's daily driver.

I tried recording it, but it just didn't sound good on my iPhone playback. I'll try again.

Yeah man that's what's cool about this when you get tired, just go back to stock and that's it. No need to spend a couple thousand on an exhaust system, when really all you want is more noise lol , put the vids up here, when you get a chance .
