My Resonator Delete (Pic + Sound Clip)

jjhan85 · 09-16-2007, 08:55 PM

i don't think thats a problem really...but i also don't think its a leak.

anyone know what this is?

jadeddjay · 10-24-2007, 11:12 AM

is there any power/tq loss or gain when you delete the resonator?

wo0t604 · 12-16-2008, 11:59 PM

hmm just a question...
kinda newbish i guess
does the e92 328i have resonators? i read somewhere that it doesn't..
was thinkin of this option to bring up a better tone without deleting the muffler or buying a new one...

E90330iS · 12-18-2008, 03:59 PM

it does, 335i coupes dont

Hi All,

Well, I have just come home from getting mine deleted today, it cost $100.

I stuck my head underneath to take a look at their workmanship and I have noticed that they have used a tad smaller diameter pipe that original which I don't think that's a big drama as the E90 pipes are huge anyway, but what I have noticed that instead of putting the 'Y' junction at the point of cutting the two engine pipes just as it went into the original resinator, they have extended the duel piping and placed the 'Y' junction where the end of the resinator would have been.

Effectively this has lengthened the two egine pipes by about 2 feet.

Does anyone believe this will be an issue ?

i doubt there's any issue.

how does it sound?

KkSc · 03-14-2009, 02:21 AM

haha...i did my resonator delete a week ago, and it makes the sound more deep!!

blue2fire · 03-24-2009, 08:56 PM

Sounds good. Very throaty.

Fritzables · 03-25-2009, 03:18 AM

G'Day Shragon,

It sound pretty good indeed. Not too loud but you can hear a sting when it all starts to resonate and as blue2fire say's - it sounds a lot more throatier.

Once I get the headers on I will have to re-evaluate as I am expecting a major increase in noise.

Fritzables.

shragon · 03-25-2009, 10:16 PM

thanks for the responses blue2fire and fritzables! do you notice any drone in the cabin?

lazyassand1balla24 · 03-25-2009, 11:06 PM

sounding good

Fritzables · 03-26-2009, 01:53 AM

Yea, I guess it's the only drawback. At first I thought it was more than excessive but one soon gets used to it and I no longer notice it.

To be truthful, mine will only drone at one small RPM range which I haven't taken notice of.

I'll tell ya what, I have some really goo audio gear so I will take it for a drive and create an 'mp3' with driving normally and driving with the drone present - both windows up and down.

Still sounds awesome though......

Pete

shragon · 03-27-2009, 01:49 AM

awesome, sounds good pete!

E90 ANdy · 04-12-2009, 06:42 PM

does any one know the diameter of the twin pipes of a 325/328/330? also... the diameter of the single pipe that is connected to the resonator... im looking to put a Y-pipe and extend the twin pipes. thanks!!

Fritzables · 04-12-2009, 07:27 PM

E90 ANdy,

Just went and meassured the resinator inlet/outlet dimensions on my old one (as I kept in case I ever wish to stick it back on) and the specs are:

Outlet: 66mm
Inlets: 50mm

These are inside diameters.

Okay cool, so basically 2x 2.25in o/d pipes to a 2.5in o/d y-pipe would work?

Thank you very very much for looking for me

Fritzables · 04-12-2009, 09:13 PM

Ok E90 ANdy,

I meassured the inlets as being 52mm OD which makes sense as it's 1mm tube but as the cut was made very close to the weld on the outlet it was difficult to atain the correct dimension.

I got 70mm OD, so seeing it's 1mm tube then I would be pretty confident it will be around 68-69mm OD.

As long as the ID is right then the outer can be anything I'm guessing. :-)

Let me know if i needa make any changes. im looking to buy some parts to make this

thanks for all the help! i hope this helps anyone who wants to do the resonator delete also! The BMW performance exhaust doesnt have a resonator.. why should we???

Fritzables · 04-13-2009, 01:38 AM

Look'n good, I was going to mention to place the actual 'Y' towards the rear, which effectively lengthens the engine pipes. This gives more low down torque.

I have a 323i which has the same pipe as the 325i.

It's a pretty simple mod for a muffler shop and only cost me $50 to get done

I have kept a close look at the welds over time and all seems good.

Go for GOLD E90 ANdy!!!!!

how does it sound with the resonator delete? any deeper? i just want a slightly louder exhaust note because my car is SUPER quiet :/

Fritzables · 04-13-2009, 02:26 AM

I have a REMUS rear muffler which are quiet in character and that's one of the reasons why I deleted the resonator.

Yes, much deeper and has a crackle when you get up around 6,000, but still very European.

There is an increase in cabin noise (drone) but this only occurs under certain conditions. I no longer notice it. I was going to get an audio clip organised to illustrate what the cab sounds like - but I have fallen into the 'SLACK' department for this week at least.

The note isn't loud at all and sounds great - just right I believe. Will be interested in your feedback actually.

Fritzables.
