I just removed all three resonators and added an x-pipe. I'll post some vids later. Sound great but I think it's still too quiet.

How's the sound at cruising speed with the top down? Any "droning?"

I'd love a more aggressive sound in town, but I spend too much time on the road to live with noise at speed.

No droning at all. It's a very mild increase in sound even at WOT. I installed the x-pipe up where the 2 canisters go and it gives you a little higher pitched note a WOT. On the highway there is no noticeable change in exhaust note, none.

I've been driving around with the top down all day and only hear a difference pulling away from a stop (and only with a heavy throttle), at WOT and when blipping for downshifts/heal-and-toe. The car does rev up faster and throttle blipping is a lot faster.

I need to drive under a few bridges to really get an idea of how loud the new setup is.

On a side note, I took a look at the resonators and was surprised to see they are basically a straight through design with perforated holes in the pipes as they pass through the resonators. So they are less restrictive than I expected.

Just figured I add in my 2 cents two months back ordered a eisenmann race mufflers installed really no change in sound wtf $3000 still sounds like stock, yesterday went to exhaust shop to have first resonator deleted and x pipe added in, picked up car still no change in sound wtf, called shop back asked them to delete final resonator before mufflers they did sound is better but still pretty quite no drone quite at idle. I was really worried about making this car sound like a rice burner but it is very hard too I guess my advice to anyone would be don't worry about deleting resonators if u are keeping the mufflers I'll try to post up some sound clips

Did mine yesterday boys! Did the x pipe toward the front. Sounds amazing! Still have the stock mufflers. Plan on changing those eventually too.

Yorgi, You once suggested you were going to do a dyno run before and after modifying your exhaust. Did you?

What I think I'm reading is that there's not much difference in sound even after removing two sets of resonators. It would be interesting to see what the torque curve looks like before/after.

That was my plan before I started working 12 hour days. Things are crazy at work so I've given up on the dyno idea.

I don't think I'll have time to dyno the Dianan intake either which I really want to do.

I did a quick video pre-delete of the car starting and reving. I'll do a second post-delete video starting/reving, in-car, drive-by under load and also in an underpass (I'm using a high-end Rode mic so this should give a good idea what the update really sounds like)

I did my first underpass rip today and it sounded pretty good. More like an M6 than a 650i and about as loud as an AMG C63. So loud but not annoying.

I haven't done any kind of test, but after removing just the front 2 "can" resonators I could definintely tell the throttle has a little more "punch" to it. I still have to remove the "box" resonator to see if that adds anything further.

If you are running the BimmerApp on your phone press and hold on a post until you see a menu (there is also a menu icon in the top right) Choose more/open in Safari (or your andriod browser) to get the full version of the forums.

On the iPhone I did not see a way to upload pics stored on the phone so you will need to first host pics on a site like photobucket.

Once you have the pics hosted copy the host site link to the pic and paste it into the prompt after clicking on the "post image" icon (mountain range).

You can also email pics on the phone to yourself then upload these from a desktop/laptop.

i try your set up
because you don't have back presure so your low end is no good but high speed might me good
i try all kind of set up on my car. so you might want to put x-pipe to give you back presure


well i'm thinking about to buy oem m6 muffler or just x-pipe set up with no muffler and 4" dual tip
does any body have x-pip with oem m6 muffler on the car?
i love to hear sound b 4 i buy

thank you

Hey guys, check out this clip. Its the magnaflow exhaust with the resonators deleted. Sounds nice! Still has a higher pitch!

Greco, That sounds extremely good.
I am trying to get mine scheduled for next week. Resonator delete (all three), Tru-X pipe
(2.25") from Magnaflow in place of the two front resonators, retaining stock exhaust.
Do you still have stock intake?

Thx,
