MadDad(TM) Dual-Outlet Quad: $1099

BMW86 · 12-07-2010, 01:52 AM

Looks like a nice design and I agree with splitting the airflow sooner. The cutout doesn't seem like a big deal either.

Is there any plans for a whisper version? If so, realistically how long?
Will there be other tip options available? Possibly more like the 1M?
I would also like to hear this on a fully catless setup.
Can you confirm zero drone, with/without catless setup.

+1 on a whisper version please...i prefer quiet and subtle.
Also, will this fit an N55.

This won't be a "Whisper" series exhaust. Its being done as a Street series. It should be quiter than the single outlet Street series do to the exhaust flow being split and will still use the custom inner baffling that was created for the Street series. If anything we "might" add a small muffler, more of a resonator(which is a small muffler) if needed. Sound testing will tell the story.

It should be plug and play for a 2011. The 2011 uses the same axleback section as the 2008-2010's.

That's just all best guesses right now and anyone that's followed some other threads know its all a moving dart board, but right now February is what I think, I'll keep thread updated as things progress.

Any chance of doing this in the center exiting Icarbon Diffuser? I think that looks a LOT better.

Maybe at some point. I know there is no way to satisfy eveyone with the first offering. We looked the the center outout and just though that it doesn't look as tidy as it does on a wider M3. It is all opinion of course I know there will be plenty of folks that would say otherwise, but for now its the mirror setup.

I'd imagine if there was earlier news we'd here it.

Excited as well.

Rich, subscribed! do you know what the weight comparison is from the single outlet dual vs. double outlet quad? Also, I LOVE my black tips on my whisper series...is this going to be an option?

So I am assuming those of us with cats/midpipes only need axle back section to convert to quad. look fwd to hearing how it sounds

I believe he did mention at one point black tips would be an option. Interesting in hearing the weight comparison when available as well.

*Edit: He mentioned in the opening thread "* You'll be able to order with the standard polished stainless steel double walled tips or have the tips black ceramic coated."

I love it!

maddad · 01-17-2011, 06:46 PM

Hi guys,

I know I have not posted in a while. We should be getting back on track in the next two weeks. We are planning on having our pre-production test unit in the next 3-4 weeks. I'll post actual weight as soon as I get the pre-prod unit.

Thanks for the update Rick. The HPF quad exhaust will be out shortly too but the design seems quite different to yours. I look forward to hearing more sound clips of this piece when it's finalised. I'm leaning towards your setup.

1-2MANY · 01-25-2011, 03:41 PM

Can't wait for for info and pics/vids. Very interested!

Orlin · 01-25-2011, 03:50 PM

looks good but I think it will be a little too loud for my taste.

A whisper quad exhaust with mufflers would be great but its downside is it would add a bit of extra weight. This quad exhaust is on my short list so long as there is ZERO drone

I wonder how it would sound with a full catless turbo back

I reckon it will sound awesome but being a street series exhaust it will be loud. I am unsure if it will be too loud for me as everyone has different taste. I cant wait to hear it though!

Why would a quad have zero drone?
